GMS6402: Medical Pulmonary Physiology Exam Questions With 100% Correct Answers 2024 The vast majority of the total surface area of the lung is found in the - answeralveoli All of the following can be measured via spirometry except - answerFunctional residual capacity (FRC) What is the muscle that is used for expiration? - answerExternal obliques What is the transpulmonary pressure if pleural pressure is -7 cm H2O and alveolar pressure is -3 cm H2O? - answer+4 cm H2O Lung compliance test indicates that a 3 cm H2O change in transpulmonary pressure generates a 0.9 L change in lung volume. What is this patient's lung compliance? - answer0.3 L of air/cm H2O Airway resistance across a set of airways is lowest under what conditions? - answerAirway 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 - answerDecrease 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? - answerObstructive lung disease When at sea level and breathing room air, the partial pressure of O2 in inspired air is what? - answer160 mmHg A patient begins to hyperventilate while sitting in a clinic on Miami Beach and breathing room air. Over the ensuing 1 minute, his PaCO2 drops to 20 mmHg. What is his PaO2 at that moment in time? - answer125 mmHg With respect to the path of O2 diffusion, the proper order for the movement of oxygen across the pulmonary capillary membrane is - answeralveolar epithelium, interstitial space, capillary basement membrane, blood
