    Diagnosis and Treatment


    • Signs of a cold
    • Frequent cough, especially at night
    • The need to use a rescue inhaler
    • Losing your breath easily (exercise-induced bronchospasm)
    • A decrease in lung function, as measured by a spirometer or peak flow meter

    Call Your Doctor About Asthma If:

    • You or another person is experiencing an asthma attack for the first time. Asthma can quickly become serious if not treated promptly and properly.
    • Your rescue inhaler (usually albuterol) does not work to relieve symptoms within 20 minutes.
    • You or the person with asthma cannot talk in complete sentences. Other things to look for: flaring nostrils; the skin between the ribs is sucked in with each breath; the lips or the skin under the nails appear grayish or bluish. These are all signs of extreme oxygen deprivation. Get immediate emergency treatment.
