Cough, barking: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

Aspiration of foreign body.

Partial obstruction of the upper airway first produces sudden hoarseness, and then a barking cough and inspiratory stridor. Other effects of this life-threatening condition include gagging, tachycardia, dyspnea, decreased breath sounds, wheezing and, possibly, cyanosis.

Epiglottiditis.

 Epiglottiditis is a life-threatening disorder that has become less common since the use of influenza vaccines. It occurs nocturnally, heralded by a barking cough and a high fever. The child is hoarse, dysphagic, dyspneic, and restless and appears extremely ill and panicky. The cough may progress to severe respiratory distress with sternal and intercostal retractions, nasal flaring, cyanosis, and tachycardia. The child will struggle to get sufficient air as epiglottic edema increases. Epiglottiditis is a true medical emergency.

Laryngotracheobronchitis (acute).

Also known as viral croup, laryngotracheobronchitis is most common in children between ages 9 and 18 months and usually occurs in the fall and early winter. It initially produces a low to moderate fever, a runny nose, a poor appetite, and an infrequent cough. When the infection descends into the laryngotracheal area, a barking cough, hoarseness, and inspiratory stridor occur.

As respiratory distress progresses, substernal and intercostal retractions occur along with tachycardia and shallow, rapid respirations. Sleeping in a dry room worsens these signs. The patient becomes restless, irritable, pale, and cyanotic.

Spasmodic croup.

 Acute spasmodic croup usually occurs during sleep with the abrupt onset of a barking cough that awakens the child. Typically, he doesn't have a fever, but may be hoarse, restless, and dyspneic. As his respiratory distress worsens, the child may exhibit sternal and intercostal retractions, nasal flaring, tachycardia, cyanosis, and an anxious, frantic appearance. The signs usually subside within a few hours, but attacks tend to recur.

Cough, productive: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

Actinomycosis.

 Actinomycosis begins with a cough that produces purulent sputum. A fever, weight loss, fatigue, weakness, dyspnea, night sweats, pleuritic chest pain, and hemoptysis may also occur.

Aspiration pneumonitis.

Aspiration pneumonitis causes coughing that produces pink, frothy and, possibly, purulent sputum. The patient also has marked dyspnea, a fever, tachypnea, tachycardia, wheezing, and cyanosis.

Bronchiectasis.

The chronic cough of bronchiectasis produces copious, mucopurulent sputum that has characteristic layering (top, frothy; middle, clear; bottom, dense with purulent particles). The patient has halitosis; his sputum may smell foul or sickeningly sweet. Other characteristic findings include hemoptysis, persistent coarse crackles over the affected lung area, occasional wheezing, rhonchi, exertional dyspnea, weight loss, fatigue, malaise, weakness, a recurrent fever, and late-stage finger clubbing.

Bronchitis (chronic).

Bronchitis causes a cough that may be nonproductive initially. Eventually, however, it produces mucoid sputum that becomes purulent. Secondary infection can also cause mucopurulent sputum, which may become blood-tinged and foul-smelling. The coughing, which may be paroxysmal during exercise, usually occurs when the patient is recumbent or rises from sleep.

The patient also exhibits prolonged expirations, increased use of accessory muscles for breathing, barrel chest, tachypnea, cyanosis, wheezing, exertional dyspnea, scattered rhonchi, coarse crackles (which can be precipitated by coughing), and late-stage clubbing.

Chemical pneumonitis.

Chemical pneumonitis causes a cough with purulent sputum. It can also cause dyspnea, wheezing, orthopnea, a fever, malaise, and crackles; mucous membrane irritation of the conjunctivae, throat, and nose; laryngitis; or rhinitis. Signs and symptoms may increase for 24 to 48 hours after exposure, then resolve; if severe, however, they may recur 2 to 5 weeks later.

Common cold.

 When the common cold causes productive coughing, the sputum is mucoid or mucopurulent. Early indications include a dry hacking cough, sneezing, a headache, malaise, fatigue, rhinorrhea (watery to tenacious, mucopurulent secretions), nasal congestion, a sore throat, myalgia, and arthralgia.

Lung abscess (ruptured).

The cardinal sign of a ruptured lung abscess is coughing that produces copious amounts of purulent, foul-smelling, and possibly blood-tinged sputum. A ruptured abscess can also cause diaphoresis, anorexia, clubbing, weight loss, weakness, fatigue, a fever with chills, dyspnea, a headache, malaise, pleuritic chest pain, halitosis, inspiratory crackles, and tubular or amphoric breath sounds. The patient's chest is dull on percussion on the affected side.

Lung cancer.

One of the earliest signs of bronchogenic carcinoma is a chronic cough that produces small amounts of purulent (or mucopurulent), blood-streaked sputum. In a patient with bronchoalveolar cancer, however, coughing produces large amounts of frothy sputum. Other signs and symptoms include dyspnea, anorexia, fatigue, weight loss, chest pain, a fever, diaphoresis, wheezing, and clubbing.

Nocardiosis.

 Nocardiosis causes a productive cough (with purulent, thick, tenacious, and possibly blood-tinged sputum) and fever that may last several months. Other findings include night sweats, pleuritic pain, anorexia, malaise, fatigue, weight loss, and diminished or absent breath sounds. The patient's chest is dull on percussion.

North American blastomycosis.

 North American blastomycosis is a chronic disorder that produces coughing that's dry and hacking or produces bloody or purulent sputum. Other findings include pleuritic chest pain, a fever, chills, anorexia, weight loss, malaise, fatigue, night sweats, cutaneous lesions (small, painless, nonpruritic macules or papules), and prostration.

Plague

(Yersinia pestis).  Plague is one of the most virulent acute bacterial infections and, if untreated, one of the most potentially lethal diseases known. Most cases are sporadic, but the potential for epidemic spread still exists. Clinical forms include bubonic (the most common), septicemic, and pneumonic plagues. The bubonic form is transmitted to a human when bitten by an infected flea. Signs and symptoms include a fever, chills, and swollen, inflamed, and tender lymph nodes near the site of the flea bite. Septicemic plague develops as a fulminant illness generally with the bubonic form. The pneumonic form may be contracted from person-to-person through direct contact via the respiratory system or through biological warfare from aerosolization and inhalation of the organism. The onset is usually sudden with chills, a fever, a headache, and myalgia. Pulmonary signs and symptoms include a productive cough, chest pain, tachypnea, dyspnea, hemoptysis, increasing respiratory distress, and cardiopulmonary insufficiency.

Pneumonia.

 Bacterial pneumonia initially produces a dry cough that becomes productive. Associated signs and symptoms develop suddenly and include shaking chills, a high fever, myalgia, a headache, pleuritic chest pain that increases with chest movement, tachypnea, tachycardia, dyspnea, cyanosis, diaphoresis, decreased breath sounds, fine crackles, and rhonchi.

Mycoplasma pneumonia may cause a cough that produces scant blood-flecked sputum. Typically, however, a nonproductive cough starts 2 to 3 days after the onset of malaise, a headache, a fever, and a sore throat. Paroxysmal coughing causes substernal chest pain. Patients may develop crackles, but generally don't appear seriously ill.

Psittacosis.

 As psittacosis progresses, the characteristic hacking cough, nonproductive at first, may later produce a small amount of mucoid, blood-streaked sputum. The infection may begin abruptly, with chills, a fever, a headache, myalgia, and prostration. Other signs and symptoms include tachypnea, fine crackles, chest pain (rare), epistaxis, photophobia, abdominal distention and tenderness, nausea, vomiting, and a faint macular rash. Severe infection may produce stupor, delirium, and coma.

Pulmonary coccidioidomycosis.

 Pulmonary coccidioidomycosis causes a nonproductive or slightly productive cough with a fever, occasional chills, pleuritic chest pain, a sore throat, a headache, backache, malaise, marked weakness, anorexia, hemoptysis, and an itchy macular rash. Rhonchi and wheezing may be heard. The disease may spread to other areas, causing arthralgia, swelling of the knees and ankles, and erythema nodosum or erythema multiforme.

Pulmonary edema.

When severe, pulmonary edema, which is a life-threatening disorder, causes a cough that produces frothy, bloody sputum. Early signs and symptoms include exertional dyspnea; paroxysmal nocturnal dyspnea, followed by orthopnea; and coughing, which may be nonproductive initially. Others include a fever, fatigue, tachycardia, tachypnea, dependent crackles, and a ventricular gallop. As the patient's respirations become increasingly rapid and labored, he develops more diffuse crackles and a productive cough, worsening tachycardia and, possibly, arrhythmias. His skin becomes cold, clammy, and cyanotic; his blood pressure falls; and his pulse becomes thready.

Pulmonary embolism.

Pulmonary embolism is a life-threatening disorder that causes a cough that may be nonproductive or may produce blood-tinged sputum. Usually, the first symptom of a pulmonary embolism is severe dyspnea, which may be accompanied by angina or pleuritic chest pain. The patient experiences marked anxiety, a low-grade fever, tachycardia, tachypnea, and diaphoresis. Less-common signs include massive hemoptysis, chest splinting, leg edema and, with a large embolus, cyanosis, syncope, and jugular vein distention. The patient may also have a pleural friction rub, diffuse wheezing, crackles, chest dullness on percussion, decreased breath sounds, and signs of circulatory collapse.

Pulmonary tuberculosis (TB).

 Pulmonary TB causes a mild to severe productive cough along with some combination of hemoptysis, malaise, dyspnea, and pleuritic chest pain. Sputum may be scant and mucoid or copious and purulent. Typically, the patient experiences night sweats, easy fatigability, and weight loss. His breath sounds are amphoric. He may have chest dullness on percussion and, after coughing, increased tactile fremitus with crackles.

Silicosis.

 A productive cough with mucopurulent sputum is the earliest sign of silicosis. The patient also has exertional dyspnea, tachypnea, weight loss, fatigue, general weakness, and recurrent respiratory infections. Auscultation reveals end-inspiratory, fine crackles at the lung bases.

Tracheobronchitis.

Inflammation initially causes a nonproductive cough that later — following the onset of chills, a sore throat, a slight fever, muscle and back pain, and substernal tightness — becomes productive as secretions increase. Sputum is mucoid, mucopurulent, or purulent. The patient typically has rhonchi and wheezes; he may also develop crackles. Severe tracheobronchitis may cause a fever of 101° to 102° F (38.3° to 38.9° C) and bronchospasm.

Other causes

Diagnostic tests.

Bronchoscopy and pulmonary function tests (PFTs) may increase productive coughing.

Drugs.

 Expectorants increase productive coughing. These include ammonium chloride, calcium iodide, guaifenesin, iodinated glycerol, potassium iodide, and terpin hydrate.

Respiratory therapy.

Intermittent positive-pressure breathing, nebulizer therapy, and incentive spirometry can help loosen secretions and cause or increase productive coughing.

Acute respiratory failure in COPD: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

ARF may develop in patients with COPD as a result of any condition that increases the work of breathing and decreases the respiratory drive. Such conditions include respiratory tract infection (such as bronchitis or pneumonia). The most common precipitating factor is bronchospasm, or accumulating secretions secondary to cough suppression. Other causes of ARF in COPD include:

❑ central nervous system (CNS) depression — head trauma or injudicious use of sedatives, opioids, tranquilizers, or oxygen (O₂)

❑ cardiovascular disorders — myocardial infarction, heart failure, or pulmonary emboli

❑ airway irritants — smoke or fumes

❑ endocrine and metabolic disorders — myxedema or metabolic alkalosis

❑ thoracic abnormalities — chest trauma, pneumothorax, or thoracic or abdominal surgery.

The incidence of ARF increases markedly with age and is especially high among people age 65 and older.

Infant respiratory distress syndrome: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Although airways and alveoli of a neonate’s respiratory system are present by 27 weeks’ gestation, the intercostal muscles are weak and the alveolar capillary system is immature. The premature neonate with IRDS develops widespread alveolar collapse due to a lack of surfactant, a lipoprotein pres-ent in alveoli and respiratory bronchioles. Surfactant lowers surface tension and helps prevent alveolar collapse. This surfactant deficiency results in widespread atelectasis, which leads to inadequate alveolar ventilation with shunting of blood through collapsed areas of lung, causing hypoxemia and acidosis.

IRDS occurs almost exclusively in neonates born before 37 weeks’ gestation (in 60% of those born before the 28th week). The incidence is greatest in the 1,000 to 1,500 g birthweight group. Infants of diabetic mothers, those born by cesarean delivery, second-born twins, infants with perinatal asphyxia, and those delivered suddenly after antepartum hemorrhage are more commonly afflicted.

Respiratory syncytial virus infection: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

The organism that causes RSV is transmitted from person to person by respiratory secretions and has an incubation period of 4 to 5 days. Antibody titers seem to indicate that few children younger than age 4 escape contracting some form of RSV, even if it's mild. In fact, RSV is the only viral disease that has its maximum impact during the first few months of life (incidence of RSV bronchiolitis peaks at age 2 months). School-age children, adolescents, and young adults with mild reinfections are probably the source of infection for infants and young children.

This virus occurs in annual epidemics during the late winter and early spring in temperate climates and during the rainy season in the tropics. It can also be seen in immunocompromised adults, especially patients with bone marrow transplants.

Severe acute respiratory syndrome: Causes
(Professional Guide to Diseases (Eighth Edition))

SARS is caused by the SARS-associated coronavirus (SARS-CoV). Coronaviruses are a common cause of mild respiratory illnesses in humans, but researchers believe that a virus may have mutated, allowing it to cause this potentially life-threatening disease.

Close contact with a person who’s infected with SARS, including contact with infectious aerosolized droplets or body secretions, is the method of transmission. Most people who contracted the disease during the 2003 outbreak contracted it during travel to endemic areas. However, the virus has been found to live on hands, tissues, and other surfaces for up to 6 hours in its droplet form. It has also been found to live in the stool of people with SARS for up to 4 days. The virus may be able to live for months or years in below-freezing temperatures.

This disorder causes coughing that produces pink, frothy, possibly purulent sputum. The patient also has marked dyspnea, fever, tachypnea, tachycardia, wheezing, and cyanosis.

Asthma (acute)

A severe asthma attack, which can be life-threatening, may produce tenacious mucoid sputum and mucus plugs. Such an attack typically starts with a dry cough and mild wheezing, then progresses to severe dyspnea, audible wheezing, chest tightness, and a productive cough. Other findings include apprehension, prolonged expiration, intercostal and supraclavicular retraction on inspiration, accessory muscle use, rhonchi, crackles, flaring nostrils, tachypnea, tachycardia, diaphoresis, and flushing or cyanosis. Attacks commonly occur at night or during sleep.

Bronchiectasis

The chronic cough of this disorder produces copious mucopurulent sputum that has characteristic layering (top, frothy; middle, clear; bottom, dense with purulent particles). The patient has halitosis: His sputum may smell foul or sickeningly sweet. Other characteristic findings include hemoptysis, persistent coarse crackles over the affected lung area, occasional wheezing, rhonchi, exertional dyspnea, weight loss, fatigue, malaise, weakness, recurrent fever, and late-stage finger clubbing.

Bronchitis (chronic)

The cough associated with chronic bronchitis may be nonproductive initially; eventually, however, it produces mucoid sputum that becomes purulent. Secondary infection can also cause mucopurulent sputum, which may become blood tinged and foul smelling. The cough, which may be paroxysmal during exercise, usually occurs when the patient is recumbent or rises from sleep.

The patient also exhibits prolonged expiration, accessory muscle use, barrel chest, tachypnea, cyanosis, wheezing, exertional dyspnea, scattered rhonchi, coarse crackles (which can be precipitated by coughing), and late-stage clubbing.

Chemical pneumonitis

This disorder causes a cough with purulent sputum. It may also cause dyspnea, wheezing, orthopnea, fever, malaise, crackles, laryngitis, rhinitis, and mucous membrane irritation of the conjunctivae, throat, and nose. Signs and symptoms may increase for 24 to 48 hours after exposure, then resolve; in severe pneumonitis, however, they may recur 2 to 5 weeks later.

Common cold

The common cold may cause a productive cough with mucoid or mucopurulent sputum, but it usually starts with a dry, hacking cough, sore throat, sneezing, rhinorrhea, and nasal congestion. Headache, malaise, fatigue, myalgia, and arthralgia may also occur.

Emphysema

This disorder causes a chronic productive cough with scant mucoid, translucent, grayish white sputum that can become mucopurulent. Patients with emphysema are typically thin and have the characteristic pink or red complexion (“pink puffer” appearance). They may also exhibit increased accessory muscle use, tachypnea, grunting expirations through pursed lips, diminished breath sounds, exertional dyspnea, rhonchi, barrel chest, anorexia, and weight loss. Clubbing is a late sign.

Legionnaires’ disease

This disorder causes a cough that produces scant mucoid, nonpurulent and, possibly, blood-streaked sputum. Prodromal signs and symptoms typically include malaise, fatigue, weakness, anorexia, diffuse myalgia, and possibly diarrhea. Within 12 to 48 hours, the patient develops a dry cough and a sudden high fever with chills. Many patients also have pleuritic chest pain, headache, tachypnea, tachycardia, nausea, vomiting, dyspnea, crackles, mild temporary amnesia, disorientation, confusion, flushing, mild diaphoresis, and prostration.

Lung abscess (ruptured)

The cardinal sign of a ruptured lung abscess is a cough that produces copious amounts of purulent, foul-smelling and, possibly, blood-tinged sputum. A ruptured abscess can also cause diaphoresis, anorexia, clubbing, weight loss, weakness, fatigue, fever with chills, dyspnea, headache, malaise, pleuritic chest pain, halitosis, inspiratory crackles, and tubular or amphoric breath sounds. The patient’s chest is dull on percussion on the affected side.

Caused by Yersinia pestis, plague is one of the most virulent and, if untreated, most lethal bacterial infections known. Most cases are sporadic, but the potential for epidemic spread still exists. Clinical forms include bubonic (the most common), septicemic, and pneumonic plagues. The bubonic form is transmitted to man from the bite of infected fleas. Signs and symptoms include fever, chills, and swollen, inflamed, and tender lymph nodes near the site of the fleabite. Septicemic plague may develop as a complication of untreated bubonic or pneumonic plague and occurs when plague bacteria enter the bloodstream and multiply. The pneumonic form can be contracted by inhaling respiratory droplets from an infected person or inhaling the organism that has been dispersed in the air through biological warfare. The onset is usually sudden with chills, fever, headache, and myalgia. Pulmonary signs and symptoms include a productive cough, chest pain, tachypnea, dyspnea, hemoptysis, increasing respiratory distress, and cardiopulmonary insufficiency.

The patient may also have a pleural friction rub, diffuse wheezing, crackles, chest dullness on percussion, decreased breath sounds, and signs of circulatory collapse.

Pulmonary tuberculosis

This disorder causes a mild to severe productive cough along with some combination of hemoptysis, malaise, dyspnea, and pleuritic chest pain. Sputum may be scant and mucoid or copious and purulent. Typically, the patient experiences night sweats, easy fatigability, and weight loss. His breath sounds are amphoric.

Respiratory acidosis: Causes
(Handbook of Diseases)

Respiratory acidosis can result from airway obstruction or parenchymal lung disease, which interferes with alveolar ventilation, or from chronic obstructive pulmonary disease (COPD), asthma, severe adult respiratory distress syndrome, chronic bronchitis, large pneumothorax, extensive pneumonia, or pulmonary edema.

Hypoventilation compromises excretion of carbon dioxide produced through metabolism. The retained carbon dioxide then combines with water to form an excess of carbonic acid, decreasing the blood pH. As a result, the concentration of hydrogen ions in body fluids, which directly reflects acidity, increases.

In addition, several factors predispose the patient to respiratory acidosis:

❑ Drugs: Narcotics, anesthetics, hypnotics, and sedatives decrease the sensitivity of the respiratory center.

❑ Central nervous system (CNS) trauma: Medullary injury may impair ventilatory drive.

❑ Chronic metabolic alkalosis: Respiratory compensatory mechanisms attempt to normalize pH by decreasing alveolar ventilation.

❑ Neuromuscular disease (such as myasthenia gravis, Guillain-Barré syndrome, and poliomyelitis): Failure of respiratory muscles to respond properly to respiratory drive reduces alveolar ventilation.

Respiratory distress syndrome: Causes
(Handbook of Diseases)

Although the airways and alveoli of a neonate’s respiratory system are present by the 27th week of gestation, the intercostal muscles are weak and the alveoli and capillary blood supply are immature. In respiratory distress syndrome, the premature neonate develops widespread alveolar collapse because of lack of surfactant, a lipoprotein present in alveoli and respiratory bronchioles.

Surfactant normally lowers surface tension and aids in maintaining alveolar patency, preventing collapse, particularly at end expiration. But a deficiency results in widespread atelectasis, which leads to inadequate alveolar ventilation with shunting of blood through collapsed areas of lung, causing hypoxia and acidosis.

Respiratory syncytial virus infection: Causes
(Handbook of Diseases)

Antibody titers seem to indicate that few children younger than age 4 escape contracting some form of RSV, even if it’s mild. In fact, RSV is the only viral disease that has its maximum impact during the first few months of life (incidence of RSV bronchiolitis peaks at age 2 months).

This virus creates annual epidemics that occur during late winter and early spring in temperate climates and during the rainy season in the tropics. The organism is transmitted from person to person by respiratory secretions and has an incubation period of 4 to 5 days. Those at higher risk include infants who are exposed to tobacco smoke, attend day-care centers, live in crowded conditions, or have school-age siblings.

Reinfection is common, producing milder symptoms than the primary infection. School-age children, adolescents, and young adults with mild re-infections are probably the source of infection for infants and young children.

Cough, barking: Medical causes
(Alarming Signs and Symptoms: Lippincott Manual of Nursing Practice Series)

Partial obstruction of the upper airway first produces sudden hoarseness, and then a barking cough and inspiratory stridor. Other effects of this life-threatening condition include gagging, tachycardia, dyspnea, decreased breath sounds, wheezing and, possibly, cyanosis.

Epiglottiditis.

As respiratory distress progresses, substernal and intercostal retractions occur along with tachycardia and shallow, rapid respirations. Sleeping in a dry room worsens these signs. The patient becomes restless, irritable, pale, and cyanotic.

Spasmodic croup.

Cough, productive: Medical causes
(Alarming Signs and Symptoms: Lippincott Manual of Nursing Practice Series)

Actinomycosis begins with a cough that produces purulent sputum. Fever, weight loss, fatigue, weakness, dyspnea, night sweats, pleuritic chest pain, and hemoptysis may also occur. Aspiration pneumonitis causes coughing that produces pink, frothy, and possibly purulent sputum. The patient also has marked dyspnea, fever, tachypnea, tachycardia, wheezing, and cyanosis. A severe asthma attack, which can be life-threatening, may produce mucoid, tenacious sputum and mucus plugs. Such an attack typically starts with a dry cough and mild wheezing, and then progresses to severe dyspnea, audible wheezing, chest tightness, and a productive cough. Other findings include apprehension, prolonged expirations, intercostal and supraclavicular retraction on inspiration, accessory muscle use, rhonchi, crackles, flaring nostrils, tachypnea, tachycardia, diaphoresis, and flushing or cyanosis. Attacks commonly occur at night or during sleep. The chronic cough of bronchiectasis produces copious, mucopurulent sputum that has characteristic layering (top, frothy; middle, clear; bottom, dense with purulent particles). The patient has halitosis; his sputum may smell foul or sickeningly sweet. Other characteristic findings include hemoptysis, persistent coarse crackles over the affected lung area, occasional wheezing, rhonchi, exertional dyspnea, weight loss, fatigue, malaise, weakness, recurrent fever, and late-stage finger clubbing. Bronchitis causes a cough that may be nonproductive initially. Eventually, however, it produces mucoid sputum that becomes purulent. Secondary infection can also cause mucopurulent sputum, which may become blood-tinged and foul-smelling. The coughing, which may be paroxysmal during exercise, usually occurs when the patient is recumbent or rises from sleep.

The patient also exhibits prolonged expirations, increased use of accessory muscles for breathing, barrel chest, tachypnea, cyanosis, wheezing, exertional dyspnea, scattered rhonchi, coarse crackles (which can be precipitated by coughing), and late-stage clubbing. Chemical pneumonitis causes a cough with purulent sputum. It can also cause dyspnea, wheezing, orthopnea, fever, malaise, and crackles; mucous membrane irritation of the conjunctivae, throat, and nose; laryngitis; or rhinitis. Signs and symptoms may increase for 24 to 48 hours after exposure, and then resolve; if severe, however, they may recur 2 to 5 weeks later.

Cough, barking: Medical causes
(Signs & Symptoms: A 2-in-1 Reference for Nurses)

Aspiration of foreign body

Partial obstruction of the upper airway caused by aspiration of foreign body first produces sudden hoarseness, then a barking cough and inspiratory stridor. Other effects of this life-threatening condition include gagging, tachycardia, dyspnea, decreased breath sounds, wheezing and, possibly, cyanosis.

Epiglottiditis

Epiglottiditis, a life-threatening disorder, has become less common since the use of influenza vaccines. It occurs nocturnally, heralded by a barking cough and a high fever. The child is hoarse, dysphagic, dyspneic, and restless and appears extremely ill and panicky. The cough may progress to severe respiratory distress with sternal and intercostal retractions, nasal flaring, cyanosis, and tachycardia. The child will struggle to get sufficient air as epiglottic edema increases. Epiglottiditis is a true medical emergency.

Laryngotracheobronchitis (acute)

Also known as viral croup, acute laryngotracheobronchitis is most common in children between 9 and 18 months old and usually occurs in the fall and early winter. It initially produces low to moderate fever, runny nose, poor appetite, and infrequent cough. When the infection descends into the laryngotracheal area, barking cough, hoarseness, and inspiratory stridor occur.

As respiratory distress progresses, substernal and intercostal retractions occur along with tachycardia and shallow, rapid respirations. Sleeping in a dry room worsens these signs. The patient becomes restless, irritable, pale, and cyanotic.

Spasmodic croup

Acute spasmodic croup usually occurs during sleep with the abrupt onset of a barking cough that awakens the child. Typically, he doesn’t have a fever but may be hoarse, restless, and dyspneic. As his respiratory distress worsens, the child may exhibit sternal and intercostal retractions, nasal flaring, tachycardia, cyanosis, and an anxious, frantic appearance. The signs usually subside within a few hours, but attacks tend to recur.

Cough, productive: Medical causes
(Signs & Symptoms: A 2-in-1 Reference for Nurses)

Aspiration pneumonitis

Aspiration pneumonitis causes coughing that produces pink, frothy, possibly purulent sputum. The patient also has marked dyspnea, fever, tachypnea, fatigue, chest pain, halitosis, tachycardia, wheezing, and cyanosis.

Asthma (acute)

A severe asthma attack, which can be life-threatening, may produce mucoid, tenacious sputum and mucus plugs. Such an attack typically starts with a dry cough and mild wheezing, then progresses to severe dyspnea, audible wheezing, chest tightness, and a productive cough. Other findings include apprehension, prolonged expirations, intercostal and supraclavicular retraction on inspiration, accessory muscle use, rhonchi, crackles, flaring nostrils, tachypnea, tachycardia, diaphoresis, and flushing or cyanosis. Attacks commonly occur at night or during sleep.

Bronchiectasis

The chronic cough of bronchiectasis produces copious, mucopurulent sputum that has characteristic layering (top, frothy; middle, clear; bottom, dense with purulent particles). The patient has halitosis: His sputum may smell foul or sickeningly sweet. Other characteristic findings include hemoptysis, persistent coarse crackles over the affected lung area, occasional wheezing, rhonchi, exertional dyspnea, weight loss, fatigue, malaise, weakness, recurrent fever, and late-stage finger clubbing.

Bronchitis (chronic)

Chronic bronchitis causes a cough that may be nonproductive initially. Eventually, however, it produces mucoid sputum that becomes purulent. Secondary infection can also cause mucopurulent sputum, which may become blood-tinged and foul-smelling. The coughing, which may be paroxysmal during exercise, usually occurs when the patient is recumbent or rises from sleep.

The patient also exhibits prolonged expirations, increased use of accessory muscles for breathing, barrel chest, tachypnea, cyanosis, wheezing, exertional dyspnea, scattered rhonchi, coarse crackles (which can be precipitated by coughing), and late-stage clubbing.

Chemical pneumonitis

Chemical pneumonitis causes a cough with purulent sputum. It can also cause dyspnea, wheezing, orthopnea, fever, malaise, and crackles; mucous membrane irritation of the conjunctivae, throat, and nose; laryngitis; or rhinitis. Signs and symptoms may increase for 24 to 48 hours after exposure, then resolve; if severe, however, they may recur 2 to 5 weeks later.

Common cold

When a common cold causes productive coughing, the sputum is mucoid or mucopurulent. Early indications of the common cold include a dry, hacking cough, sneezing, headache, malaise, fatigue, rhinorrhea (watery to tenacious, mucopurulent secretions), nasal congestion, sore throat, myalgia, and arthralgia.

Legionnaires’ disease

Legionnaires’ disease causes a cough that produces scant mucoid, nonpurulent, possibly blood-streaked sputum. Prodromal signs and symptoms typically include malaise, fatigue, weakness, anorexia, diffuse myalgia and, possibly, diarrhea. Then, within 48 hours, the patient develops a dry cough and a sudden high fever with chills. Many patients also have pleuritic chest pain, headache, tachypnea, tachycardia, nausea, vomiting, dyspnea, crackles, mild temporary amnesia, disorientation, confusion, flushing, mild diaphoresis, and prostration.

Lung abscess (ruptured)

The cardinal sign of ruptured lung abscess is coughing that produces copious amounts of purulent, foul-smelling, possibly blood-tinged sputum. A ruptured abscess can also cause diaphoresis, anorexia, clubbing, weight loss, weakness, fatigue, fever with chills, dyspnea, headache, malaise, pleuritic chest pain, halitosis, inspiratory crackles, and tubular or amphoric breath sounds. The patient’s chest is dull on percussion on the affected side.

Lung cancer

One of the earliest signs of bronchogenic carcinoma is a chronic cough that produces small amounts of purulent (or mucopurulent), blood-streaked sputum. In a patient with bronchoalveolar cancer, however, coughing produces large amounts of frothy sputum. Other signs and symptoms include dyspnea, anorexia, fatigue, weight loss, chest pain, fever, diaphoresis, wheezing, and clubbing.

Plague

Signs and symptoms of plague, caused by the bacterium Yersinia pestis, include fever, chills, and swollen, inflamed, and tender lymph nodes near the site of the flea bite. Septicemic plague develops as a fulminant illness generally with the bubonic form. The onset of the pneumonic form is usually sudden with chills, fever, headache, and myalgia. Pulmonary signs and symptoms include productive cough, chest pain, tachypnea, dyspnea, hemoptysis, increasing respiratory distress, and cardiopulmonary insufficiency.

Pneumonia

Bacterial pneumonia initially produces a dry cough that becomes productive. Associated signs and symptoms develop suddenly and include shaking chills, high fever, myalgia, headache, pleuritic chest pain that increases with chest movement, tachypnea, tachycardia, dyspnea, cyanosis, diaphoresis, decreased breath sounds, fine crackles, and rhonchi.

Pulmonary edema

Severe, pulmonary edema is a life-threatening disorder that causes a cough that produces frothy, bloody sputum. Early signs and symptoms of pulmonary edema include exertional dyspnea; paroxysmal nocturnal dyspnea, followed by orthopnea; and coughing, which may be nonproductive initially. Others include fever, fatigue, tachycardia, tachypnea, dependent crackles, and ventricular gallop. As the patient’s respirations become increasingly rapid and labored, he develops more diffuse crackles and a productive cough, worsening tachycardia and, possibly, arrhythmias. His skin becomes cold, clammy, and cyanotic; his blood pressure falls; and his pulse becomes thready.

Pulmonary embolism

Pulmonary embolism is a life-threatening disorder that causes a cough that may be nonproductive or may produce blood-tinged sputum. Usually, the first symptom of a pulmonary embolism is severe dyspnea, which may be accompanied by angina or pleuritic chest pain. The patient experiences marked anxiety, a low-grade fever, tachycardia, tachypnea, and diaphoresis. Less common signs include massive hemoptysis, chest splinting, leg edema and, with a large embolus, cyanosis, syncope, and distended neck veins. The patient may also have a pleural friction rub, diffuse wheezing, crackles, chest dullness on percussion, decreased breath sounds, and signs of circulatory collapse.

Pulmonary emphysema

Pulmonary emphysema causes a chronic productive cough with scant, mucoid, translucent, grayish white sputum that can become mucopurulent. The patient is thin and has the characteristic “pink puffer” appearance with weight loss, increased accessory muscle use, tachypnea, grunting expirations through pursed lips, diminished breath sounds, exertional dyspnea, rhonchi, barrel chest, and anorexia. Clubbing is a late sign.

Pulmonary tuberculosis

Pulmonary tuberculosis causes a mild to severe productive cough along with some combination of hemoptysis, malaise, dyspnea, and pleuritic chest pain. Sputum may be scant and mucoid or copious and purulent. Typically, the patient experiences night sweats, easy fatigability, and weight loss. His breath sounds are amphoric. He may have chest dullness on percussion and, after coughing, increased tactile fremitus with crackles.

Silicosis

A productive cough with mucopurulent sputum is the earliest sign of silicosis. The patient also has exertional dyspnea, tachypnea, weight loss, fatigue, general weakness, and recurrent respiratory infections. Auscultation reveals end-inspiratory, fine crackles at the lung bases.

Tracheobronchitis

With tracheobronchitis, inflammation initially causes a nonproductive cough that later — following the onset of chills, sore throat, slight fever, muscle and back pain, and substernal tightness — becomes productive as secretions increase. Sputum is mucoid, mucopurulent, or purulent. The patient typically has rhonchi and wheezes; he may also develop crackles. Severe tracheobronchitis may cause a fever of 101° to 102° F (38.3° to 38.9° C) and bronchospasm.

Other causes

Diagnostic tests

Bronchoscopy and pulmonary function tests may increase productive coughing.

Drugs

Expectorants, of course, increase productive coughing. These include guaifenesin, potassium iodide, and terpin hydrate.

Respiratory therapy

Intermittent positive-pressure breathing, nebulizer therapy, and incentive spirometry can help loosen secretions and cause or increase productive coughing.

Cough, productive: Medical causes
(Nursing: Interpreting Signs and Symptoms)

Actinomycosis.Actinomycosis begins with a cough that produces purulent sputum. A fever, weight loss, fatigue, weakness, dyspnea, night sweats, pleuritic chest pain, and hemoptysis may also occur.

Aspiration pneumonitis.Aspiration pneumonitis causes coughing that produces pink, frothy and, possibly, purulent sputum. The patient also has marked dyspnea, a fever, tachypnea, tachycardia, wheezing, and cyanosis.

Bronchiectasis.The chronic cough of bronchiectasis produces copious, mucopurulent sputum that has characteristic layering (top, frothy; middle, clear; bottom, dense with purulent particles). The patient has halitosis; his sputum may smell foul or sickeningly sweet. Other characteristic findings include hemoptysis, persistent coarse crackles over the affected lung area, occasional wheezing, rhonchi, exertional dyspnea, weight loss, fatigue, malaise, weakness, a recurrent fever, and late-stage finger clubbing.

Bronchitis (chronic).Bronchitis causes a cough that may be nonproductive initially. Eventually, however, it produces mucoid sputum that becomes purulent. Secondary infection can also cause mucopurulent sputum, which may become blood-tinged and foul-smelling. The coughing, which may be paroxysmal during exercise, usually occurs when the patient is recumbent or rises from sleep.

The patient also exhibits prolonged expirations, increased use of accessory muscles for breathing, barrel chest, tachypnea, cyanosis, wheezing, exertional dyspnea, scattered rhonchi, coarse crackles (which can be precipitated by coughing), and late-stage clubbing.

Chemical pneumonitis.Chemical pneumonitis causes a cough with purulent sputum. It can also cause dyspnea, wheezing, orthopnea, a fever, malaise, and crackles; mucous membrane irritation of the conjunctivae, throat, and nose; laryngitis; or rhinitis. Signs and symptoms may increase for 24 to 48 hours after exposure, then resolve; if severe, however, they may recur 2 to 5 weeks later.

Common cold.When the common cold causes productive coughing, the sputum is mucoid or mucopurulent. Early indications include a dry hacking cough, sneezing, a headache, malaise, fatigue, rhinorrhea (watery to tenacious, mucopurulent secretions), nasal congestion, a sore throat, myalgia, and arthralgia.

Lung abscess (ruptured).The cardinal sign of a ruptured lung abscess is coughing that produces copious amounts of purulent, foul-smelling and, possibly, blood-tinged sputum. A ruptured abscess can also cause diaphoresis, anorexia, clubbing, weight loss, weakness, fatigue, a fever with chills, dyspnea, a headache, malaise, pleuritic chest pain, halitosis, inspiratory crackles, and tubular or amphoric breath sounds. The patient's chest is dull on percussion on the affected side.

Lung cancer.One of the earliest signs of bronchogenic carcinoma is a chronic cough that produces small amounts of purulent (or mucopurulent), blood-streaked sputum. In a patient with bronchoalveolar cancer, however, coughing produces large amounts of frothy sputum. Other signs and symptoms include dyspnea, anorexia, fatigue, weight loss, chest pain, a fever, diaphoresis, wheezing, and clubbing.

Nocardiosis.Nocardiosis causes a productive cough (with purulent, thick, tenacious, and possibly blood-tinged sputum) and fever that may last several months. Other findings include night sweats, pleuritic pain, anorexia, malaise, fatigue, weight loss, and diminished or absent breath sounds. The patient's chest is dull on percussion.

North American blastomycosis.North American blastomycosis is a chronic disorder that produces coughing that's dry and hacking or produces bloody or purulent sputum. Other findings include pleuritic chest pain, a fever, chills, anorexia, weight loss, malaise, fatigue, night sweats, cutaneous lesions (small, painless, nonpruritic macules or papules), and prostration.

Plague(Yersinia pestis).The pneumonic form of plague may be contracted from person-to-person through direct contact via the respiratory system or through biological warfare from aerosolization and inhalation of the organism. The onset is usually sudden with chills, a fever, a headache, and myalgia. Pulmonary signs and symptoms include a productive cough, chest pain, tachypnea, dyspnea, hemoptysis, increasing respiratory distress, and cardiopulmonary insufficiency.

Pneumonia.Bacterial pneumonia initially produces a dry cough that becomes productive. Associated signs and symptoms develop suddenly and include shaking chills, a high fever, myalgia, headache, pleuritic chest pain that increases with chest movement, tachypnea, tachycardia, dyspnea, cyanosis, diaphoresis, decreased breath sounds, fine crackles, and rhonchi.

Mycoplasma pneumonia may cause a cough that produces scant blood-flecked sputum. Typically, however, a nonproductive cough starts 2 or 3 days after the onset of malaise, a headache, a fever, and a sore throat. Paroxysmal coughing causes substernal chest pain. Patients may develop crackles, but generally don't appear seriously ill.

Psittacosis.As psittacosis progresses, the characteristic hacking cough, nonproductive at first, may later produce a small amount of mucoid, blood-streaked sputum. The infection may begin abruptly, with chills, a fever, a headache, myalgia, and prostration. Other signs and symptoms include tachypnea, fine crackles, chest pain (rare), epistaxis, photophobia, abdominal distention and tenderness, nausea, vomiting, and a faint macular rash. Severe infection may produce stupor, delirium, and coma.

Pulmonary coccidioidomycosis.Pulmonary coccidioidomycosis causes a nonproductive or slightly productive cough with a fever, occasional chills, pleuritic chest pain, a sore throat, a headache, backache, malaise, marked weakness, anorexia, hemoptysis, and an itchy macular rash. Rhonchi and wheezing may be heard. The disease may spread to other areas, causing arthralgia, swelling of the knees and ankles, and erythema nodosum or erythema multiforme.

Pulmonary edema.Severe, pulmonary edema, which is a life-threatening disorder, causes a cough that produces frothy, bloody sputum. Early signs and symptoms include exertional dyspnea; paroxysmal nocturnal dyspnea, followed by orthopnea; and coughing, which may be nonproductive initially. Others include a fever, fatigue, tachycardia, tachypnea, dependent crackles, and a ventricular gallop. As the patient's respirations become increasingly rapid and labored, he develops more diffuse crackles and a productive cough, anxiety, restlessness, worsening tachycardia and, possibly, arrhythmias. His skin becomes cold, clammy, and cyanotic; his blood pressure falls; and his pulse becomes thready.

Pulmonary embolism.Pulmonary embolism is a life-threatening disorder that causes a cough that may be nonproductive or may produce blood-tinged sputum. Usually, the first symptom of a pulmonary embolism is severe dyspnea, which may be accompanied by angina or pleuritic chest pain. The patient experiences marked anxiety, a low-grade fever, tachycardia, tachypnea, and diaphoresis. Less-common signs include massive hemoptysis, chest splinting, leg edema and, with a large embolus, cyanosis, syncope, and jugular vein distention. The patient may also have a pleural friction rub, diffuse wheezing, crackles, chest dullness on percussion, decreased breath sounds, and signs of circulatory collapse.

Pulmonary tuberculosis (TB).Pulmonary TB causes a mild to severe productive cough along with some combination of hemoptysis, malaise, dyspnea, and pleuritic chest pain. Sputum may be scant and mucoid or copious and purulent. Typically, the patient experiences night sweats, easy fatigability, and weight loss. His breath sounds are amphoric. He may have chest dullness on percussion and, after coughing, increased tactile fremitus with crackles.

Silicosis.A productive cough with mucopurulent sputum is the earliest sign of silicosis. The patient also has exertional dyspnea, tachypnea, weight loss, fatigue, general weakness, and recurrent respiratory infections. Auscultation reveals end-inspiratory, fine crackles at the lung bases.

Tracheobronchitis.Inflammation initially causes a nonproductive cough that later—following the onset of chills, a sore throat, a slight fever, muscle and back pain, and substernal tightness—becomes productive as secretions increase. Sputum is mucoid, mucopurulent, or purulent. The patient typically has rhonchi and wheezes; he may also develop crackles. Severe tracheobronchitis may cause a fever of 101° to 102° F (38.3° to 38.9° C) and bronchospasm.

Other causes

Diagnostic tests.Bronchoscopy and pulmonary function tests (PFTs) may increase productive coughing.

Drugs.Expectorants increase productive coughing. These include ammonium chloride, calcium iodide, guaifenesin, iodinated glycerol, potassium iodide, and terpin hydrate.

Respiratory therapy.Intermittent positive-pressure breathing, nebulizer therapy, and incentive spirometry can help loosen secretions and cause or increase productive coughing.
