Asthma in Aircrew: Assessment, Treatment and Disposition,
DEFENCE AND CIVIL INST OF ENVIRONMENTAL MEDICINE DOWNSVIEW (ONTARIO)
Pagination or Media Count:
Asthma represents a spectrum of increased airway reactivity from mildly increased responsiveness through to severe life-threatening bronchospasm. Rational recommendations for treatment and aeromedical disposition require a careful assessment of bronchial reactivity through correlation of the clinical findings with results of pulmonary function testing including an objective measure of airway reactivity . Airway challenge testing with methacholine allows a safe, objective assessment of airway reactivity. In the Canadian Forces, aircrew candidates with a history of wheezing, recurrent cough or bronchitis in childhood, or abnormal screening PFTs are further screened with an airway challenge test. Applicants with a PC20 less than 4 mgmi are disqualified from pilot selection, and less than 2 mgml from other aircrew.
