Study Notes
- Asthma is characterized by diffuse airway inflammation.
- Asthma is caused by a variety of triggering stimuli.
- Asthma results in partially or completely reversible bronchoconstriction.
- Asthma symptoms include dyspnea, chest tightness, cough, and wheezing.
- Most severe asthma exacerbations that are treated in the emergency department resolve within 2 hours after presentation.
- The onset and duration of symptoms and the worsening of airflow obstruction before presentation are variable, but these problems usually occur over several hours.
- Even in fatal or near-fatal asthma attacks, there is potential for early recognition and aggressive treatment.
- Rarely, a patient has rapid, catastrophic onset of acute asthma, which can be fatal.
Asthma Rescue Drugs
- Short-acting beta-agonists like Albuterol are available under the trade names Proventil, ProAir, and Ventolin
- Anticholinergics like Ipratropium are available under the trade name Atrovent
- Combination drugs such as Ipratropium and albuterol are available under the trade name DuoNeb.
- Systemic corticosteroids such as Prednisone are mainly generic.
Long-Term Asthma Control
- Inhaled corticosteroids like Fluticasone are available under the trade name Flovent.
- Long-acting beta-adrenergic agonists like Salmeterol are available under the trade name Serevent Diskus.
Signs of a Potentially Fatal Asthma Attack
- Use of accessory muscles of respiration is a sign of a potentially fatal asthma attack
- Heart rate greater than 120 beats/min or increasing could mean a potentially fatal asthma attack.
- Respiratory rate greater than 25-30 breaths/min is a sign of a potentially fatal asthma attack
- Difficulty speaking because of dyspnea or fatigue may suggest a potentially fatal asthma attack
- Altered level of consciousness might be a sign of a potentially fatal asthma attack
- Quiet chest in a patient who has dyspnea or reduced level of consciousness may suggest the patient is experiencing a potentially fatal asthma attack
- Diaphoresis may be a sign of a potentially fatal asthma attack
- Inability to lie in the supine position because of breathing distress may suggest a potentially fatal asthma attack
- Peak expiratory flow (PEF) is a sign of a potentially fatal asthma attack
