A 17-year-old student has experienced reversible, periodic attacks of chest tightness with coughing,wheezing, and hyperpnea. She states that expiration is more difficult than inspiration. She is mostcomfortable sitting forward with arms leaning on some support. Chest X-rays revealed mild overinflationof the lungs. Results from laboratory and pulmonary function tests are as follows:FrequencyVital capacity (VC)20 breaths/min2.9 LFEV1.01.4 LFEV1.0/FVC56%Functional residual capacity (FRC) 3.89 LTotal lung capacity (TLC)6.82 LРа0270 mm HgРаСО226 mm HgPulse108 b/minВР120/76 mm HgIntermittent use of a bronchial smooth muscle dilator (1:1000 epinephrine by nebulizer) for several dayscaused marked improvement, resulting in the following laboratory and pulmonary function tests:VC4.15 LFEV1.03.1 LFEV1.0/FVC >75%FRC3.7 LTLC5.96LPaO289 mm HgРаСО238 mm HgPulse129 b/minВР122/78 mm Hg
