Stridor: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

Airway trauma

Local trauma to the upper airway commonly causes acute obstruction, resulting in the sudden onset of stridor. Accompanying this sign are dysphonia, dysphagia, hemoptysis, cyanosis, accessory muscle use, intercostal retractions, nasal flaring, tachypnea, progressive dyspnea, and shallow respirations. Palpation may reveal subcutaneous crepitation in the neck or upper chest.

Anaphylaxis

With a severe allergic reaction, upper airway edema and laryngospasm cause stridor and other signs and symptoms of respiratory distress: nasal flaring, wheezing, accessory muscle use, intercostal retractions, and dyspnea. The patient may also develop nasal congestion and profuse, watery rhinorrhea. Typically, these respiratory effects are preceded by a feeling of impending doom or fear, weakness, diaphoresis, sneezing, nasal pruritus, urticaria, erythema, and angioedema. Common associated findings include chest or throat tightness, dysphagia and, possibly, signs of shock, such as hypotension, tachycardia, and cool, clammy skin.

Anthrax (inhalation)

Initial signs and symptoms are flulike and include a fever, chills, weakness, a cough, and chest pain. The disease generally occurs in two stages with a period of recovery after the initial symptoms. The second stage develops abruptly with rapid deterioration marked by stridor, a fever, dyspnea, and hypotension generally leading to death within 24 hours. Radiologic findings include mediastinitis and symmetric mediastinal widening.

Aspiration of a foreign body

Sudden stridor is characteristic in foreign body aspiration, a life-threatening situation. Related findings include an abrupt onset of dry, paroxysmal coughing; gagging or choking; hoarseness; tachycardia; wheezing; dyspnea; tachypnea; intercostal muscle retractions; diminished breath sounds; cyanosis; and shallow respirations. The patient typically appears anxious and distressed.

Hypocalcemia

With hypocalcemia, laryngospasm can cause stridor. Other findings include paresthesia, carpopedal spasm, and positive Chvostek’s and Trousseau’s signs.

Inhalation injury

Within 48 hours after inhalation of smoke or noxious fumes, the patient may develop laryngeal edema and bronchospasms, resulting in stridor. Associated signs and symptoms include singed nasal hairs, orofacial burns, coughing, hoarseness, sooty sputum, crackles, rhonchi, wheezes, and other signs and symptoms of respiratory distress, such as dyspnea, accessory muscle use, intercostal retractions, and nasal flaring.

Mediastinal tumor

Commonly producing no symptoms at first, a mediastinal tumor may eventually compress the trachea and bronchi, resulting in stridor. Its other effects include hoarseness, a brassy cough, a tracheal shift or tug, dilated neck veins, swelling of the face and neck, stertorous respirations, and suprasternal retractions on inspiration. The patient may also report dyspnea, dysphagia, and pain in the chest, shoulder, or arm.

Retrosternal thyroid

Retrosternal thyroid is an anatomic abnormality that causes stridor, dysphagia, a cough, hoarseness, and tracheal deviation. It can also cause signs of thyrotoxicosis.

Other causes

Diagnostic tests

Bronchoscopy or laryngoscopy may precipitate laryngospasm and stridor.

Treatments

After prolonged intubation, the patient may exhibit laryngeal edema and stridor when the tube is removed. Aerosol therapy with epinephrine may reduce stridor. Reintubation may be necessary in some cases. Neck surgery, such as thyroidectomy, may cause laryngeal paralysis and stridor.

Wheezing [Sibilant rhonchi]: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

Anaphylaxis

Anaphylaxis is an allergic reaction that can cause tracheal edema or bronchospasm, resulting in severe wheezing and stridor. Initial signs and symptoms include fright, weakness, sneezing, dyspnea, nasal pruritus, urticaria, erythema, and angioedema. Respiratory distress occurs with nasal flaring, accessory muscle use, and intercostal retractions. Other findings include nasal edema and congestion; profuse, watery rhinorrhea; chest or throat tightness; and dysphagia. Cardiac effects include arrhythmias and hypotension.

Aspiration of a foreign body

Partial obstruction by a foreign body produces sudden onset of wheezing and possibly stridor; a dry, paroxysmal cough; gagging; and hoarseness. Other findings include tachycardia, dyspnea, decreased breath sounds and, possibly, cyanosis. A retained foreign body may cause inflammation leading to fever, pain, and swelling.

Aspiration pneumonitis

With aspiration pneumonitis, wheezing may accompany tachypnea, marked dyspnea, cyanosis, tachycardia, fever, productive (eventually purulent) cough, and pink, frothy sputum.

Asthma

Wheezing is an initial and cardinal sign of asthma. It’s heard at the mouth during expiration. An initially dry cough later becomes productive with thick mucus. Other findings include apprehension, prolonged expiration, intercostal and supraclavicular retractions, rhonchi, accessory muscle use, nasal flaring, and tachypnea. Asthma also produces tachycardia, diaphoresis, and flushing or cyanosis.

Bronchial adenoma

Bronchial adenoma, an insidious disorder, produces unilateral, possibly severe wheezing. Common features are chronic cough and recurring hemoptysis. Symptoms of airway obstruction may occur later.

Bronchiectasis

Excessive mucus commonly causes intermittent and localized or diffuse wheezing. A copious, foul-smelling, mucopurulent cough is classic. It’s accompanied by hemoptysis, rhonchi, and coarse crackles. Weight loss, fatigue, weakness, exertional dyspnea, fever, malaise, halitosis, and late-stage clubbing may also occur.

Bronchitis (chronic)

Bronchitis causes wheezing that varies in severity, location, and intensity. Associated findings include prolonged expiration, coarse crackles, scattered rhonchi, and a hacking cough that later becomes productive. Other effects include dyspnea, accessory muscle use, barrel chest, tachypnea, clubbing, edema, weight gain, and cyanosis.

Bronchogenic carcinoma

Obstruction may cause localized wheezing. Typical findings include a productive cough, dyspnea, hemoptysis (initially blood-tinged sputum, possibly leading to massive hemorrhage), anorexia, and weight loss. Upper extremity edema and chest pain may also occur.

Emphysema

Mild to moderate wheezing may occur with emphysema, a form of chronic obstructive pulmonary disease. Related findings include dyspnea, malaise, tachypnea, diminished breath sounds, peripheral cyanosis, pursed-lip breathing, anorexia, and malaise. Accessory muscle use, barrel chest, a chronic productive cough, and clubbing may also occur.

Pulmonary coccidioidomycosis

Pulmonary coccidioidomycosis may cause wheezing and rhonchi along with cough, fever, chills, pleuritic chest pain, headache, weakness, malaise, anorexia, and macular rash.

Pulmonary edema

Wheezing may occur with pulmonary edema, a life-threatening disorder. Other signs and symptoms include coughing, exertional and paroxysmal nocturnal dyspnea and, later, orthopnea. Examination reveals tachycardia, tachypnea, dependent crackles, and a diastolic gallop. Severe pulmonary edema produces rapid, labored respirations; diffuse crackles; a productive cough with frothy, bloody sputum; arrhythmias; cold, clammy, cyanotic skin; hypotension; and thready pulse.

Tracheobronchitis

Auscultation may detect wheezing, rhonchi, and crackles. The patient also has a cough, slight fever, sudden chills, muscle and back pain, and substernal tightness.

Wegener’s granulomatosis

Wegener’s granulomatosis may cause mild to moderate wheezing if it compresses major airways. Other findings include a cough (possibly bloody), dyspnea, pleuritic chest pain, hemorrhagic skin lesions, and progressive renal failure. Epistaxis and severe sinusitis are common.

Stridor: Medical causes
(Professional Guide to Signs & Symptoms (Fifth Edition))

Airway trauma

Anaphylaxis

Anthrax, inhalation

Initial signs and symptoms are flulike and include fever, chills, weakness, cough, and chest pain. The disease generally occurs in two stages with a period of recovery after the initial symptoms. The second stage develops abruptly with rapid deterioration marked by stridor, fever, dyspnea, and hypotension generally leading to death within 24 hours. Radiologic findings include mediastinitis and symmetric mediastinal widening.

Aspiration of a foreign body

Sudden stridor is characteristic in this life-threatening situation. Related findings include abrupt onset of dry, paroxysmal coughing, gagging or choking, hoarseness, tachycardia, wheezing, dyspnea, tachypnea, intercostal muscle retractions, diminished breath sounds, cyanosis, and shallow respirations. The patient typically appears anxious and distressed.

Epiglottiditis

With this inflammatory condition, stridor is caused by an erythematous, edematous epiglottis that obstructs the upper airway. Stridor occurs along with fever, sore throat, and a croupy cough.

Hypocalcemia

With this disorder, laryngospasm can cause stridor. Other findings include paresthesia, carpopedal spasm, and positive Chvostek’s and Trousseau’s signs.

Inhalation injury

Laryngeal tumor

Stridor is a late sign and may be accompanied by dysphagia, dyspnea, enlarged cervical nodes, and pain that radiates to the ear. Typically, stridor is preceded by hoarseness, minor throat pain, and a mild, dry cough.

Laryngitis (acute)

This disorder may cause severe laryngeal edema, resulting in stridor and dyspnea. Its chief sign, however, is mild to severe hoarseness, perhaps with transient voice loss. Other findings include sore throat, dysphagia, dry cough, malaise, and fever.

Mediastinal tumor

Commonly producing no symptoms at first, this type of tumor may eventually compress the trachea and bronchi, resulting in stridor. Its other effects include hoarseness, brassy cough, tracheal shift or tug, dilated neck veins, swelling of the face and neck, stertorous respirations, and suprasternal retractions on inspiration. The patient may also report dyspnea, dysphagia, and pain in the chest, shoulder, or arm.

Retrosternal thyroid

This anatomic abnormality causes stridor, dysphagia, cough, hoarseness, and tracheal deviation. It can also cause signs of thyrotoxicosis.

Thoracic aortic aneurysm

If this aneurysm compresses the trachea, it may cause stridor accompanied by dyspnea, wheezing, and a brassy cough. Other findings include hoarseness or complete voice loss, dysphagia, jugular vein distention, prominent chest veins, tracheal tug, paresthesia or neuralgia, and edema of the face, neck, and arms. The patient may also complain of substernal, lower back, abdominal, or shoulder pain.

Other causes

Diagnostic tests

Bronchoscopy or laryngoscopy may precipitate laryngospasm and stridor.

Respiratory distress occurs with nasal flaring, accessory muscle use, and intercostal retractions. Other findings include nasal edema and congestion, profuse watery rhinorrhea, chest or throat tightness, and dysphagia. Cardiac effects include arrhythmias and hypotension.

Aspiration of a foreign body

Partial obstruction by a foreign body produces sudden onset of wheezing and possibly stridor; a dry, paroxysmal cough; gagging; and hoarseness. Other findings include tachycardia, dyspnea, decreased breath sounds, and possibly cyanosis. A retained foreign body may cause inflammation leading to fever, pain, and swelling.

Aspiration pneumonitis

In this disorder, wheezing may accompany tachypnea, marked dyspnea, cyanosis, tachycardia, fever, a productive (eventually purulent) cough, and frothy pink sputum.

Asthma

Blast lung injury

Wheezing is a common symptom of this condition, which is characterized by hypoxia and respiratory difficulty. The forceful blast wave that follows an explosive detonation can cause serious lung injury, including hemorrhage, contusion, edema, and tearing. In addition to wheezing, patients may exhibit chest pain, dyspnea, cyanosis, and hemoptysis. The diagnosis is confirmed by chest X-rays that show a classic “butterfly” pattern.

Bronchial adenoma

This insidious disorder produces unilateral, possibly severe wheezing. Common features are a chronic cough and recurring hemoptysis. Symptoms of airway obstruction may occur later.

Bronchiectasis

In this disorder, excessive mucus commonly causes intermittent and localized or diffuse wheezing. Characteristic findings include a chronic cough that produces copious amounts of foul-smelling, mucopurulent sputum; hemoptysis; rhonchi; and coarse crackles. Weight loss, fatigue, weakness, exertional dyspnea, fever, malaise, halitosis, and late-stage clubbing may also occur.

Bronchitis (chronic)

This disorder causes wheezing that varies in severity, location, and intensity. Associated findings include prolonged expiration, coarse crackles, scattered rhonchi, and a hacking cough that later becomes productive. Other effects include dyspnea, accessory muscle use, barrel chest, tachypnea, clubbing, edema, weight gain, and cyanosis.

Bronchogenic carcinoma

Chemical pneumonitis (acute)

Mucosal injury causes increased secretions and edema, leading to wheezing, dyspnea, orthopnea, crackles, malaise, fever, and a productive cough with purulent sputum. The patient may also have signs of conjunctivitis, pharyngitis, laryngitis, and rhinitis.

Emphysema

Mild to moderate wheezing may occur in this form of chronic obstructive pulmonary disease. Related findings include dyspnea, tachypnea, diminished breath sounds, peripheral cyanosis, pursed-lip breathing, anorexia, and malaise. Accessory muscle use, barrel chest, a chronic productive cough, and clubbing may also occur.

Inhalation injury

Early findings include hoarseness and coughing, singed nasal hairs, orofacial burns, and soot-stained sputum. Later effects may include wheezing, crackles, rhonchi, and respiratory distress.

Pneumothorax (tension)

This life-threatening disorder causes respiratory distress with possible wheezing, dyspnea, tachycardia, tachypnea, and sudden, severe, sharp chest pain (often unilateral). Other findings include a dry cough, cyanosis, accessory muscle use, asymmetrical chest wall movement, anxiety, and restlessness. Examination reveals hyperresonance or tympany and diminished or absent breath sounds on the affected side, subcutaneous crepitation, decreased vocal fremitus, and tracheal deviation.

Pulmonary coccidioidomycosis

This disorder may cause wheezing and rhonchi along with cough, fever, chills, pleuritic chest pain, headache, weakness, malaise, anorexia, and macular rash.

Pulmonary edema

This life-threatening disorder may cause wheezing, coughing, exertional and paroxysmal nocturnal dyspnea and, later, orthopnea. Examination reveals tachycardia, tachypnea, dependent crackles, and a diastolic gallop. Severe pulmonary edema produces rapid, labored respirations; diffuse crackles; a productive cough with frothy, bloody sputum; arrhythmias; cold, clammy, cyanotic skin; hypotension; and a thready pulse.

Pulmonary embolus

Diffuse, mild wheezing rarely occurs in this disorder, which is characterized by dyspnea, chest pain, and cyanosis.

Pulmonary tuberculosis

In late stages, fibrosis causes wheezing. Common findings include a mild to severe productive cough with pleuritic chest pain and fine crackles, night sweats, anorexia, weight loss, fever, malaise, dyspnea, and fatigue. Examination reveals dullness on percussion, increased tactile fremitus, and amphoric breath sounds.

Respiratory syncytial virus (RSV)

Infected individuals commonly develop wheezing and other symptoms within 4 to 6 days of exposure to this virus. Healthy adults and children older than age 3 usually have mild cases of RSV and experience wheezing along with other common cold-like symptoms of runny nose, cough, and low-grade fever. In children ages 3 and younger, high-pitched expiratory wheezing can accompany a severe cough, rapid breathing, and high-grade fever. RSV is the primary cause of lower respiratory tract infection in infants, who may develop pneumonia or bronchiolitis. Infection-control practices help prevent the spread of this virus, which can be inactivated by disinfectants or soap and water. A vaccine is being researched for this common condition that affects most children by age 2.

Thyroid goiter

This disorder may produce no symptoms, or it may cause wheezing, dysphagia, and respiratory difficulty related to a compressed airway.

Tracheobronchitis

Auscultation may detect wheezing, rhonchi, and crackles. The patient also has a cough, a slight fever, sudden chills, muscle and back pain, and substernal tightness.

Wegener’s granulomatosis

This disorder may cause mild to moderate wheezing if it compresses major airways. Other findings include a cough (possibly bloody), dyspnea, pleuritic chest pain, hemorrhagic skin lesions, and progressive renal failure. Epistaxis and severe sinusitis are common.

The patient may also report dyspnea, dysphagia, and pain in the chest, shoulder, or arm.

Thoracic aortic aneurysm

If a thoracic aortic aneurysm compresses the trachea, it may cause stridor accompanied by dyspnea, wheezing, and a brassy cough. Other findings include hoarseness or complete voice loss, dysphagia, jugular vein distention, prominent chest veins, tracheal tug, paresthesia or neuralgia, and edema of the face, neck, and arms. The patient may also complain of substernal, lower back, abdominal, or shoulder pain.

Other causes

Diagnostic tests

Bronchoscopy or laryngoscopy may precipitate laryngospasm and stridor.

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

Anaphylaxis

Anaphylaxis is an allergic reaction that can cause tracheal edema or bronchospasm, resulting in severe wheezing and stridor. Initial signs and symptoms of anaphylaxis include fright, weakness, sneezing, dyspnea, nasal pruritus, urticaria, erythema, and angioedema. Respiratory distress occurs with nasal flaring, accessory muscle use, and intercostal retractions. Other findings include nasal edema and congestion; profuse, watery rhinorrhea; chest or throat tightness; and dysphagia. Cardiac effects include arrhythmias and hypotension.

Aspiration of a foreign body

Partial obstruction by a foreign body produces sudden onset of wheezing and possibly stridor; a dry, paroxysmal cough; gagging; and hoarseness. Other findings include tachycardia, dyspnea, decreased breath sounds, and possibly cyanosis. A retained foreign body may cause inflammation leading to fever, pain, and swelling.

Aspiration pneumonitis

With aspiration pneumonitis, wheezing may accompany tachypnea, marked dyspnea, cyanosis, tachycardia, fever, productive (eventually purulent) cough, and pink, frothy sputum.

Asthma

Bronchial adenoma

Bronchial adenoma is an insidious disorder that produces unilateral, possibly severe wheezing. Common features are chronic cough and recurring hemoptysis. Symptoms of airway obstruction may occur later.

Bronchiectasis

With bronchiectasis, excessive mucus commonly causes intermittent and localized or diffuse wheezing. A copious, foul-smelling, mucopurulent cough is classic. The cough is accompanied by hemoptysis, rhonchi, and coarse crackles. Weight loss, fatigue, weakness, exertional dyspnea, fever, malaise, halitosis, and late-stage clubbing may also occur.

Bronchitis (chronic)

Bronchogenic carcinoma

Obstruction from bronchogenic carcinoma may cause localized wheezing. Typical findings include a productive cough, dyspnea, hemoptysis (initially blood-tinged sputum, possibly leading to massive hemorrhage), anorexia, and weight loss. Upper extremity edema and chest pain may also occur.

Chemical pneumonitis (acute)

With acute chemical pneumonitis, mucosal injury causes increased secretions and edema, leading to wheezing, dyspnea, orthopnea, crackles, malaise, fever, and a productive cough with purulent sputum. The patient may also have signs of conjunctivitis, pharyngitis, laryngitis, and rhinitis.

Emphysema

Inhalation injury

Wheezing may eventually occur with inhalation injury. Early findings include hoarseness and coughing, singed nasal hairs, orofacial burns, and soot-stained sputum. Later effects are crackles, rhonchi, and respiratory distress.

Pneumothorax (tension)

Tension pneumothorax, a life-threatening disorder, causes respiratory distress with possible wheezing, dyspnea, tachycardia, tachypnea, and sudden, severe, sharp chest pain (often unilateral). Other findings include a dry cough, cyanosis, accessory muscle use, asymmetrical chest wall movement, anxiety, and restlessness. Examination reveals hyperresonance or tympany and diminished or absent breath sounds on the affected side, subcutaneous crepitation, decreased vocal fremitus, and tracheal deviation.

Pulmonary coccidioidomycosis

Pulmonary coccidioidomycosis may cause wheezing and rhonchi along with cough, fever, chills, pleuritic chest pain, headache, weakness, fatigue, sore throat, backache, malaise, anorexia, and an itchy, macular rash.

Pulmonary edema

Wheezing may occur with pulmonary edema , a life-threatening disorder. Other signs and symptoms of pulmonary edema include coughing, exertional and paroxysmal nocturnal dyspnea and, later, orthopnea. Examination reveals tachycardia, tachypnea, dependent crackles, and a diastolic gallop. Severe pulmonary edema produces rapid, labored respirations; diffuse crackles; a productive cough with frothy, bloody sputum; arrhythmias; cold, clammy, cyanotic skin; hypotension; and thready pulse.

Pulmonary tuberculosis

In late stages, fibrosis causes wheezing. Common findings include a mild to severe productive cough with pleuritic chest pain and fine crackles, night sweats, anorexia, weight loss, fever, malaise, dyspnea, and fatigue. Other features are dullness to percussion, increased tactile fremitus, and amphoric breath sounds.

CULTURAL CUE:Those living in Appalachian regions have a 50% higher mortality from tuberculosis than the national average. They also have a higher incidence of pneumonia, influenza, and black lung disease. The higher rate of respiratory tract diseases may be related to the high-risk occupations of the region, such as those in the mining, timber, and textile industries.

Thyroid goiter

Thyroid goiter may not produce symptoms, or it may cause wheezing, dysphagia, and respiratory difficulty related to a compressed airway. The neck will appear swollen and distended.

Tracheobronchitis

Auscultation of the patient with tracheobronchitis may detect wheezing, rhonchi, and moist or coarse crackles. The patient also has a cough, slight fever, sudden chills, muscle and back pain, and substernal tightness.

Stridor: Medical causes
(Nursing: Interpreting Signs and Symptoms)

Airway trauma.Local trauma to the upper airway commonly causes acute obstruction, resulting in the sudden onset of stridor. Accompanying this sign are dysphonia, dysphagia, hemoptysis, cyanosis, accessory muscle use, intercostal retractions, nasal flaring, tachypnea, progressive dyspnea, and shallow respirations. Palpation may reveal subcutaneous crepitation in the neck or upper chest.

Anaphylaxis.With a severe allergic reaction, upper airway edema and laryngospasm cause stridor and other signs and symptoms of respiratory distress: nasal flaring, wheezing, accessory muscle use, intercostal retractions, and dyspnea. The patient may also develop nasal congestion and profuse, watery rhinorrhea. Typically, these respiratory effects are preceded by a feeling of impending doom or fear, weakness, diaphoresis, sneezing, nasal pruritus, urticaria, erythema, and angioedema. Common associated findings include chest or throat tightness, dysphagia and, possibly, signs of shock, such as hypotension, tachycardia, and cool, clammy skin.

Anthrax (inhalation).Initial signs and symptoms of anthrax are flulike and include fever, chills, weakness, cough, and chest pain. The disease generally occurs in two stages with a period of recovery after the initial symptoms. The second stage develops abruptly with rapid deterioration marked by stridor, fever, dyspnea, and hypotension generally leading to death within 24 hours. Radiologic findings include mediastinitis and symmetric mediastinal widening.

Hypocalcemia.With hypocalcemia, laryngospasm can cause stridor. Other findings include paresthesia, carpopedal spasm, and positive Chvostek's and Trousseau's signs.

Inhalation injury.Within 48 hours after inhalation of smoke or noxious fumes, the patient may develop laryngeal edema and bronchospasms, resulting in stridor. Associated signs and symptoms include singed nasal hairs, orofacial burns, coughing, hoarseness, sooty sputum, crackles, rhonchi, wheezes, and other signs and symptoms of respiratory distress, such as dyspnea, accessory muscle use, intercostal retractions, and nasal flaring.

Mediastinal tumor.Commonly producing no symptoms at first, a mediastinal tumor may eventually compress the trachea and bronchi, resulting in stridor. Its other effects include hoarseness, a brassy cough, a tracheal shift or tug, dilated neck veins, swelling of the face and neck, stertorous respirations, and suprasternal retractions on inspiration. The patient may also report dyspnea, dysphagia, and pain in the chest, shoulder, or arm.

Retrosternal thyroid.Retrosternal thyroid causes stridor, dysphagia, cough, hoarseness, and tracheal deviation. It can also cause signs of thyrotoxicosis.

Other causes

Diagnostic tests.Bronchoscopy or laryngoscopy may precipitate laryngospasm and stridor.

Foreign body aspiration.Sudden stridor is characteristic in foreign body aspiration, a life-threatening situation. Related findings include an abrupt onset of dry, paroxysmal coughing; gagging or choking; hoarseness; tachycardia; wheezing; dyspnea; tachypnea; intercostal muscle retractions; diminished breath sounds; cyanosis; and shallow respirations. The patient typically appears anxious and distressed.

Treatments.After prolonged intubation, the patient may exhibit laryngeal edema and stridor when the tube is removed. Aerosol therapy with epinephrine may reduce stridor. Reintubation may be necessary in some cases. Neck surgery, such as thyroidectomy, may cause laryngeal paralysis and stridor.

Wheezing [Sibilant rhonchi]: Medical causes
(Nursing: Interpreting Signs and Symptoms)

Anaphylaxis.Anaphylaxis can cause tracheal edema or bronchospasm, resulting in severe wheezing and stridor. Initial signs and symptoms include fright, weakness, sneezing, dyspnea, nasal pruritus, urticaria, erythema, and angioedema. Respiratory distress occurs with nasal flaring, accessory muscle use, and intercostal retractions. Other findings include nasal edema and congestion; profuse, watery rhinorrhea; chest or throat tightness; and dysphagia. Cardiac effects include arrhythmias and hypotension.

Aspiration pneumonitis.With aspiration pneumonitis, wheezing may accompany tachypnea, marked dyspnea, cyanosis, tachycardia, fever, productive (eventually purulent) cough, and pink, frothy sputum.

Asthma.Wheezing is an initial and cardinal sign of asthma. It's heard at the mouth during expiration. An initially dry cough later becomes productive with thick mucus. Other findings include apprehension, prolonged expiration, intercostal and supraclavicular retractions, rhonchi, accessory muscle use, nasal flaring, and tachypnea. Asthma also produces tachycardia, diaphoresis, and flushing or cyanosis.

Blast lung injury.Wheezing is a common symptom of blast lung injury, which is characterized by hypoxia and respiratory difficulty. The forceful blast wave that follows an explosive detonation can cause serious lung injury, including hemorrhage, contusion, edema, and tearing. In addition to wheezing, patients may exhibit chest pain, dyspnea, cyanosis, and hemoptysis. The diagnosis is confirmed by chest X-rays that show a classic “butterfly” pattern.

Bronchial adenoma.Bronchial adenoma produces unilateral, possibly severe wheezing. Common features are chronic cough and recurring hemoptysis. Symptoms of airway obstruction may occur later.

Bronchiectasis.With bronchiectasis, excessive mucus commonly causes intermittent and localized or diffuse wheezing. A copious, foul-smelling, mucopurulent cough is classic. It's accompanied by hemoptysis, rhonchi, and coarse crackles. Weight loss, fatigue, weakness, exertional dyspnea, fever, malaise, halitosis, and late-stage clubbing may also occur.

Bronchitis (chronic).Bronchitis causes wheezing that varies in severity, location, and intensity. Associated findings include prolonged expiration, coarse crackles, scattered rhonchi, and a hacking cough that later becomes productive. Other effects include dyspnea, accessory muscle use, barrel chest, tachypnea, clubbing, edema, weight gain, and cyanosis.

Bronchogenic carcinoma.Obstruction from bronchogenic carcinoma may cause localized wheezing. Typical findings include a productive cough, dyspnea, hemoptysis (initially blood-tinged sputum, possibly leading to massive hemorrhage), anorexia, and weight loss. Upper extremity edema and chest pain may also occur.

Emphysema.Mild to moderate wheezing may occur with emphysema. Related findings include dyspnea, tachypnea, diminished breath sounds, peripheral cyanosis, pursed-lip breathing, anorexia, and malaise. Accessory muscle use, barrel chest, a chronic productive cough, and clubbing may also occur.

Pulmonary coccidioidomycosis.Pulmonary coccidioidomycosis may cause wheezing and rhonchi along with cough, fever, chills, pleuritic chest pain, headache, weakness, malaise, anorexia, and macular rash.

Pulmonary edema.Wheezing may occur with pulmonary edema, a life-threatening disorder. Other signs and symptoms include coughing, exertional and paroxysmal nocturnal dyspnea and, later, orthopnea. Examination reveals tachycardia, tachypnea, dependent crackles, and a diastolic gallop. Severe pulmonary edema produces rapid, labored respirations; diffuse crackles; a productive cough with frothy, bloody sputum; arrhythmias; cold, clammy, cyanotic skin; hypotension; and thready pulse.

Respiratory syncytial virus (RSV).Individuals infected with RSV commonly develop wheezing and other symptoms within 4 to 6 days of exposure to this virus. Healthy adults and children older than age 3 usually have mild cases of RSV and experience wheezing along with other common cold-like symptoms of runny nose, cough, and low-grade fever. In children ages 3 and younger, high-pitched expiratory wheezing can accompany a severe cough, rapid breathing, and high-grade fever.

Tracheobronchitis.With tracheobronchitis, auscultation may detect wheezing, rhonchi, and crackles. The patient also has a cough, slight fever, sudden chills, muscle and back pain, and substernal tightness.

Wegener's granulomatosis.Wegener's granulomatosis may cause mild to moderate wheezing if it compresses major airways. Other findings include a cough (possibly bloody), dyspnea, pleuritic chest pain, hemorrhagic skin lesions, and progressive renal failure. Epistaxis and severe sinusitis are common.

Other causes

Foreign body aspiration. Partial obstruction by a foreign body produces sudden onset of wheezing and possibly stridor; a dry, paroxysmal cough; gagging; and hoarseness. Other findings include tachycardia, dyspnea, decreased breath sounds and, possibly, cyanosis. A retained foreign body may cause inflammation leading to fever, pain, and swelling.

Tracheitis: Tracheitis - pathophysiology
(The 5-Minute Pediatric Consult)

Epithelial damage from a viral infection or mechanical trauma (endotracheal intubation, surgical procedure) occurs in the trachea at the level of the cricoid cartilage. As a result, the damaged tissue is more susceptible to bacterial superinfection.
Mucosal damage characterized by marked subglottic edema, copious purulent secretions, and a pseudomembrane (mucosal lining, inflammatory products, and bacteria). These changes lead to marked airway obstruction.
Toxic shock syndrome may be a consequence if the infection is associated with toxin-producing strains of Staphylococcus aureus or Streptococcus pyogenes.

Tracheitis - etiology

Bacteria:
- Staphylococcus aureus (most common), group A β-hemolytic streptococcus, Moraxella catarrhalis, and nontypeable H. influenzae
- Pseudomonas aeruginosa, other Gram-negative enteric bacteria have been associated with nosocomial infections.
- Mycobacterium tuberculosis, Mycoplasma pneumoniae, Corynebacterium diphtheria, H. influenzae type B, and respiratory anaerobic bacteria are uncommon pathogens.
Viruses: Influenza, parainfluenza, respiratory syncytial, herpes simplex, and measles viruses have been found with bacterial pathogen(s).
Fungi: Seen with underlying immunodeficiency disorders or chronic steroid use
