Symptoms of Asthma



Symptoms of Asthma: Introduction

The classic hallmark of asthma is wheezing. This is a whistling sound that is created as air is forced through the narrowed airways in the lungs of a person with asthma. It is often heard when a person with asthma exhales, but may also be heard when a person inhales. Some wheezing can be heard by the naked ear, but it is not unusual to need to use a stethoscope to hear it. In severe cases, it may be difficult to hear wheezing because the airway have become so narrowed that there is not enough air moving through them to create the sound.

Other typical symptoms include chest tightness, cough, shortness of breath, anxiety, restlessness, pallor of the skin, and a "retracting" of the muscles that surround and encase the rib cage. When retractions happen, the ribcage appears to be working very hard and the muscles in and above it appear to be "sucking in" with breathing. Early signs of an execration of asthma can be subtle and can include restless, anxiety, and wheezing that cannot be heard by the naked ear. Because it is always best to catch and treat an exacerbation of asthma early, learning to recognize the early symptoms of asthma is an important step on minimizing severe episodes.

Asthma: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

An asthma attack may begin dramatically, with simultaneous onset of many severe symptoms, or insidiously, with gradually increasing respiratory distress. It typically includes progressively worsening shortness of breath, cough, wheezing, and chest tightness or some combination of these signs or symptoms.

During an acute attack, the cough sounds tight and dry. As the attack subsides, tenacious mucoid sputum is produced (except in young children, who don’t expectorate). Characteristic wheezing may be accompanied by coarse rhonchi, but fine crackles aren’t heard unless associated with a related complication. Between acute attacks, breath sounds may be normal.

The intensity of breath sounds in symptomatic asthma is typically reduced. A prolonged phase of forced expiration is typical of airflow obstruction. Evidence of lung hyperinflation (use of accessory muscles, for example) is particularly common in children. Acute attacks may be accompanied by tachycardia, tachypnea, and diaphoresis. In severe attacks, the patient may be unable to speak more than a few words without pausing for breath. Cyanosis, confusion, and lethargy indicate the onset of respiratory failure.

Asthma: Signs and symptoms
(Handbook of Diseases)

An acute asthma attack begins dramatically, with simultaneous onset of severe multiple symptoms, or insidiously, with gradually increasing respiratory distress. Asthma that occurs with cyanosis, confusion, and lethargy indicates the onset of life-threatening status asthmaticus and respiratory failure. Symptoms of bronchial airway obstruction may persist between acute episodes.

Signs and symptoms of asthma include:

  • sudden dyspnea, wheezing, and tightness in the chest
  • coughing that produces thick, clear, or yellow sputum
  • tachypnea, along with use of accessory respiratory muscles
  • rapid pulse
  • profuse perspiration
  • hyperresonant lung fields
  • diminished breath sounds.

    In 1997, the National Heart, Lung, and Blood Institute of the National Institutes of Health identified four levels of asthma severity based on the frequency of symptoms and exacerbations, effects on activity level, and lung function study results: mild intermittent, mild persistent, moderate persistent, and severe persistent.

    Findings for mild intermittent asthma include the following:

  • Symptoms occur less than twice per week.
  • The patient is asymptomatic with normal peak expiratory flow (PEF) between exacerbations.
  • Brief exacerbations (from a few hours to a few days) vary in intensity.
  • Nighttime symptoms occur less than twice per month.
  • Lung function studies show forced expiratory volume in 1 second (FEV1) or PEF greater than 80% of normal values; PEF may vary by less than 20%.

    Findings for mild persistent asthma include the following:

  • Symptoms occur more than twice per week, but less than once per day; exacerbations may affect activity.
  • Nighttime symptoms occur more than twice per month.
  • Lung function studies show FEV1 or PEF greater than 80% of normal values; PEF may vary by 20% to 30%.

    Findings for moderate persistent asthma include the following:

  • Symptoms occur daily.
  • Exacerbations occur more than twice per week and may last for days; exacerbations affect activity.
  • A bronchodilator is used daily.
  • Nighttime symptoms occur more than once per week.
  • Lung function studies show FEV1 or PEF 60% to 80% of normal values; PEF may vary by greater than 30%.

    Findings for severe persistent asthma include the following:

  • Symptoms occur on a continuous basis.
  • Exacerbations occur frequently and limit physical activity.
  • Nighttime symptoms occur frequently.
  • Lung function studies show FEV1 or PEF less than 60% of normal values; PEF may vary by greater than 30%.

    Article Excerpts About Symptoms of Asthma:

    Genes and Disease by the National Center for Biotechnology (Excerpt)

    It is a chronic inflammatory disorder of the airways characterized by coughing, shortness of breath, and chest tightness. A variety of "triggers" may initiate or worsen an asthma attack, including viral respiratory infections, exercise, and exposure to irritants such as tobacco smoke. The physiological symptoms of asthma are a narrowing of the airways caused by edema (fluid in the intracellular tissue space) and the influx of inflammatory cells into the walls of the airways.

    Asthma A Concern for Minority Populations, NIAID Fact Sheet: NIAID (Excerpt)

    Asthma is a chronic lung disease characterized by episodes of airflow obstruction. Symptoms of an asthma attack include

    • coughing
    • wheezing
    • shortness of breath
    • chest tightness
    (Source: excerpt from Asthma A Concern for Minority Populations, NIAID Fact Sheet: NIAID)

    NHLBI, Asthma & Physical Activity in the School: NHLBI (Excerpt)

    Acute symptoms require prompt action to help students resume their activities as soon as possible. Prompt action is also required to prevent an episode from becoming more serious or even life-threatening. Table 3 lists the symptoms that indicate an acute asthma episode and the need for immediate action. The student's asthma plan and the school's emergency plan should be easily accessible so that all staff, substitutes, volunteers, and aides know what to do.

    Table 3. Acute Symptoms Requiring Prompt Action
    • Coughing or wheezing

    • Difficulty in breathing

    • Chest tightness or pressure--reported by the student

    • Other signs, such as low peak flow readings as indicated on the asthma management plan.

    Symptoms of exercise-induced asthma (coughing, wheezing, pain or chest tightness) may last several minutes to an hour or more. These symptoms are quite different from breathlessness (deep, rapid breathing) that quickly returns to normal after aerobic exercise (Source: excerpt from NHLBI, Asthma & Physical Activity in the School: NHLBI)

    NHLBI, Asthma & Physical Activity in the School: NHLBI (Excerpt)

    Students may have symptoms that do not indicate an acute episode needing immediate treatment, but instead indicate that their asthma is not under complete control. Table 4 lists these signs.

    Table 4. Signs That May Indicate Poorly Controlled Asthma
    • A persistent cough

    • Coughing, wheezing, chest tightness, or shortness of breath after vigorous physical activity, on a recurring basis

    • Low level of stamina during physical activity or reluctance to participate.
