A 2006 Newsweek article called him history's most debunked doctor.. While his theories have been the subject of considerable controversy and debate, his impact on psychology, therapy, and culture is undeniable.
DLCO or TLCO (diffusing capacity or transfer factor of the lung for carbon monoxide (CO),[1]) is the extent to which oxygen passes from the air sacs of the lungs into the blood. Commonly, it refers to the test used to determine this parameter.
In fact, the DLCO/VA is the transfer coefficient for the diffusion of CO into the blood, and is an essential part of the equation used to calculate the DLCO. 10 The global diffusing capacity is calculated as the DLCO/VA multiplied by the overall lung volume, VA.he primary reason for this is likely that the DLCO and DLCO/VA are static measures of oxygen diffusing capacity. Yet, the exchange of oxygen under conditions of exercise is very complex, involving alterations in pulmonary blood flow, lung volume and metabolism.
