What is this patient's lung compliance? - ANSWER : 0.3 L of air/cm H2O Airway resistance across a set of airways is lowest under what conditions? - ANSWER : Airway radius is large and length of the tube is small As the lungs fill with air and we move from a low lung volume to a higher lung volume, airway resistance will - ANSWER : Decrease exponentially A patient performs an expiratory forced vital capacity maneuver. His FVC is 2 L and his FEV1 is 1 L. Based on these numbers, you would predict this patient suffers from what? - ANSWER : Obstructive lung disease
