Introduction cont., Diffusing capacity (also referred to as transfer factor) is usually measured using small concentrations of carbon monoxide (CO) and is referred to as DLCO or DCO. DLCO is used to assess the gas-exchange ability of the lungs, specifically oxygenation of mixed venous blood. Diffusing capacity is a measure of how well oxygen and carbon dioxide are transferred (diffused) between the lungs and the blood, and can be a useful test in the diagnosis and to monitor treatment of lung diseases. Diffusing capacity can also be important prior to lung surgery as a predictor of how well the surgery will be tolerated. 2012-12-28 Diffusion Capacity Test Definition - What does Diffusion Capacity Test mean?

This test measures how well your lungs transfer a small amount of carbon monoxide (CO) into the blood Diffusion capacity is generally estimated using the single breath test using carbon monoxide (CO) . CO is used due to its high affinity for hemoglobin, which is The carbon monoxide (CO) diffusing capacity of the lung. (DLCO), also known single breath DLNO test are not available yet, because in previous studies8,10 23 Mar 2005 Single-breath testing technique standardisation issues . diffusing capacity of the lung for CO (DL,CO) by the North.
It contains practice questions for your benefit as well. Carbon monoxide (CO) is tightly and rapidly bound to hemoglobin in the blood, so the partial pressure of CO in the capillaries is negligible and the second term in the denominator can be ignored.

Diffusion capacity assesses how well a tracer gas in inspired air can cross from the air into the blood. The test measures the absorption of a low concentration of carbon monoxide in inhaled air by hemoglobin in red blood cells that circulate through pulmonary capillaries. 2017-11-20
