Problem 1 A student with a mild case of asthma was feeling perfectly well when she left for class. On the way to class she breathes cold, dry air and develops a moderate asthma attack. She takes an inhaled medication (isoproterenol) that relieves the symptoms. A. Modeling the lung as a single resistor and a single capacitor attached in series, what are the peak-to-peak pleural pressure swings in each case below? Assume lung compliance C L stays fixed at 0.1 L · cm H 2 O –1 , that the student breathes using a square-wave flow pattern with equal inspiratory and expiratory times, and that R insp and R exp are equal. R
