What is the formula for determining residual volume (RV). Determine the residual volume (RV) before and after the use of the bronchodilator. a. RV before using the bronchodilator: b. RV after using the bronchodilator:

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 most comfortable sitting forward with arms leaning on some support. Chest X-rays revealed mild overinflation of the lungs. Results from laboratory and pulmonary function tests are as follows: Frequency 20 breaths/min Vital capacity (VC) 2.9 L FEV1.0 1.4 L FEV1.0/FVC 56% Functional residual capacity (FRC) 3.89 L Total lung capacity (TLC) 6.82 L Ра02 70 mm Hg РаСО2 26 mm Hg Pulse 108 b/min ВР 120/76 mm Hg Intermittent use of a bronchial smooth muscle dilator (1:1000 epinephrine by nebulizer) for several days caused marked improvement, resulting in the following laboratory and pulmonary function tests: VC 4.15 L FEV1.0 3.1 L FEV1.0/FVC >75% FRC 3.7 L TLC 5.96L PaO2 89 mm Hg PaCO2 38 mm Hg Pulse 129 b/min ВР 122/78 mm Hg
