Question

Quizplus · Accepted Answer

The diffusing capacity, often measured in the context of pulmonary function tests, is typically expressed in units of mL CO per minute per mm Hg (mL/min/mm Hg). This unit reflects the volume of gas (in this case, carbon monoxide) that can diffuse across the lung barrier per minute for a given pressure difference (in mm Hg).
