A beta 2-adrenergic agent was prescribed for further use because it has less cardiostimulatory (beta1) effect. Based on your knowledge of beta1 and beta2 receptors, why is this a good suggestion?

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: 20 breaths/min Frequency 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 PaO2 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 Pa02 89 mm Hg РаСО2 38 mm Hg Pulse 129 b/min ВР 122/78 mm Hg
