Abstract

We concluded that in COPD patients, PaO(2) appeared to be maintained better when peripheral gas exchange coped with tissue demand without an increase in CO. Conversely, when the physiological increase in CO could not maintain adequate tissue gas exchange, PaO(2) continued to fall due to the cumulative effects of increasing CO on VA/Q inequalities and low PvO(2).
