ASTHMA ATTACK

Main Symptoms

  • Use this guideline only if a physician has previously diagnosed you as having asthma, asthmatic bronchitis, or reactive airway disease.
  • Asthma symptoms include recurring episodes of wheezing, cough, chest tightness, and difficulty breathing.
  • Wheezing is a high-pitched or whistling sound heard when you breathe out.

General Information

  • Asthma Triggers - Different things can cause an asthma attack. These things are called asthma triggers.
    • Allergens (pollen, house dust, mold, animal dander)
    • Sudden changes in the weather (generally cold weather)
    • Irritants (cigarette smoke, dirt, pollution)
    • Infections (cold or flu)
    • Exercise
  • Peak Flow Meters: Peak flow meters measure how fast an adult can move air out of the lungs. Every adult asthmatic should have a peak flow meter. These measurements are very useful for grading the severity of an asthma attack.
    • Mild attack: PEFR 80-100% of baseline (personal best) (green zone)
    • Moderate attack: PEFR 50-80% (yellow zone)
    • Severe attack: PEFR less than 50% (red zone)
    • In general, medications should be increased when the PEFR is less than 80% of baseline and an adult should be seen immediately in an office or emergency department if the PEFR is less than 50%.

HOME CARE ADVICE FOR MILD ASTHMA ATTACK

  1. Quick-Relief Asthma Medicine:  
    • Start your quick-relief medicine (e.g. albuterol inhaler or nebulizer) at the first sign of any coughing or shortness of breath (don't wait for wheezing). Use inhaler (2 puffs each time) or nebulizer q 4 hours. Continue the quick-relief medicine until you have not wheezed or coughed for 48 hours.
    • The best "cough medicine" for an adult with asthma is always the asthma medicine. (Note: Don't use cough suppressants, but cough drops may help a tickly cough.)
  2. Long-Term-Control Asthma Medicine: If you are using a controller medicine (e.g. inhaled steroids or cromolyn), continue to take it as directed.
  3. Fluids: Try to drink normal amount of clear fluids (e.g. water). (Reason: adequate hydration makes it easier to cough up the sticky lung mucus.)
  4. Humidifier: If the air is dry, use a cool mist humidifier to prevent drying of the upper airway.
  5. Hay Fever: For nose allergy symptoms, it's OK to take antihistamines. (Reasons: poor control of allergic rhinitis makes asthma worse, whereas antihistamines don't make asthma worse).
  6. Remove Allergens: Take a shower to remove pollens, animal dander, or other allergens from the body and hair.
  7. Avoid Triggers: Avoid known triggers of asthma attacks (e.g. tobacco smoke, cats, other pets, feather pillows, exercise)
  8. Work with Your Doctor: There is no cure for asthma but you can take charge and learn to control it. The best way to take charge of asthma is to work with your doctor (over many months) to find the right controller (preventive) medicine so your asthma is under control. If you keep having asthma attacks, then the asthma is not under control. People can die from asthma if they do not take it seriously and work with a doctor to control it.
  9. Expected Course: If treatment is started early, most asthma attacks are quickly brought under control. All wheezing should be gone by 5 days.
  10. Call Your Doctor If:
    • Inhaled asthma medicine (nebulizer or inhaler) is needed more often than every 4 hours
    • Wheezing has not completely cleared after 5 days
    • You become worse or develop any of the "Call Your Doctor" symptoms.
