PHYS 506 Anatomy and Physiology Respiratory MCQs Answers Lung Compartments 1. A spirometer can be used to directly measure which of the following? (A) Functional residual capacity (B) Peak flow rate (C) Residual volume (D) Total lung capacity (E) Vital capacity Answer: E. A spirometer is an instrument that records the volume of air moved into and out of the lungs during breathing, and therefore can only be used to measure lung volumes and capacities that can be exchanged with the envi...

How often should a patient use CPAP correct answers Every night four hours per day otherwise health insurance won't pay Why does obstructive sleep apnea cause strokes correct answers Because the heart has to pump harder to get the blood out to the tissues. Body loses oxygen saturation causing the person to become hypoxemic making the heart pump faster causing clots in the ventricles. When you're saturation drops the ventricle gets weaker and weaker Do patients snore with central sleep ap...

In which of the following situations is volume-controlled ventilation sometimes used? - ANSWER: I. When a precise PaCO2 has to be maintained (some closed-head injuries). II. When more even distribution of ventilation is required Spontaneous breath modes include all of the following except: - ANSWER: continuous mandatory ventilation assist-control. What is the primary physiological effect of positive end-expiratory pressure (PEEP)? - ANSWER: Increase the functional residual capacity (FRC...
