What is the purpose of the spirometry measurement?
A) To evaluate the cause of hypoxia
B) To measure the volume and flow rate during forced expiration
C) To measures the gas diffusion rate at the alveolocapillary membrane
D) To determine pH and oxygen and carbon dioxide concentrations

Question

Quizplus · Accepted Answer

Spirometry measures volume and flow rate during forced expiration.The alveolar-arterial oxygen gradient is used to evaluate the cause of hypoxia.Diffusing capacity is a measure of the gas diffusion rate at the alveolocapillary membrane.Arterial blood gas analysis can be used to determine pH and oxygen and carbon dioxide concentrations.
