C)measure the residual volume.
D)assess the alveolar-capillary membrane.

Question

Quizplus · Accepted Answer

The pulmonary diffusion capacity of carbon monoxide test is used to assess the alveolar-capillary membrane by measuring the diffusion of carbon monoxide from alveoli into red blood cells in the pulmonary capillaries. It is not used to assess the patient's blood carbon monoxide level, remove carbon monoxide from the patient's blood, or measure the residual volume.
