Question

Quizplus · Accepted Answer

The diffusing capacity of the lung (DLCO)is the amount of gas entering the pulmonary blood flow per unit of time and is relative to the difference between the partial pressures of the gas in the alveoli and in the pulmonary blood.Three key factors causing abnormal DLCO are decreased quantity of hemoglobin,increased thickness of the alveolar-capillary membrane,and decreased functional surface area available for diffusion.
