In vivo estimates of NO and CO conductance for haemoglobin and for lung transfer in humans
HJP Guénard, JB Martinot, S Martin, B Maury… - Respiratory physiology …, 2016 - Elsevier
Membrane conductance (Dm) and capillary lung volume (Vc) derived from NO and CO lung
transfer measurements in humans depend on the blood conductance (θ) values of both
gases. Many θ values have been proposed in the literature. In the present study,
measurements of CO and NO transfer while breathing 15% or 21% O 2 allowed the
estimation of θ NO and the calculation of the optimal equation relating 1/θ CO to pulmonary
capillary oxygen pressure (PcapO 2). In 10 healthy subjects, the mean calculated θ NO …
