Transcutaneous PCO2 for Exercise Gas Exchange Efficiency in Chronic Obstructive Pulmonary Disease
2021
figshare.com
Gas exchange inefficiency and dynamic hyperinflation contributes to exercise limitation in chronic obstructive pulmonary disease (COPD). It is also characterized by an elevated fraction of physiological dead space (VD/VT). Noninvasive methods for accurate VD/VT assessment during exercise in patients are lacking. The current study sought to compare transcutaneous PCO2 (TcPCO2) with the gold standard—arterial PCO2 (PaCO2)—and other available methods (end tidal CO2 and the Jones equation) for
