Web23 aug. 2024 · The same thing happens in our lungs as the gases move in and out of the blood from a high to a low partial pressure. Blood entering the lungs is what we call oxygen-poor, as it lost oxygen while ... WebBesides ventilation, the diffusion of respiratory gases represents an important element in the assessment of pulmonary function. This is made possible in everyday clinical practice through the measurement of uptake of carbon monoxide (CO) into the blood. This is referred to as transfer factor.
WebDLCO is a quantitative measurement of gas transfer in the lungs. Diseases that decrease blood flow to the lungs or damage alveoli will cause less efficient gas exchange, resulting in a lower DLCO ...
