Can someone please explain the difference PO2 and PaO2?
网页2009年4月10日 · PO2 is just partial pressure of oxgen in a given environment, such as room air. 21% O2 in standard barometric pressure of 760mmHg means usual PO2 in room air is 760 x 0.21 = 160mmHg. PAO2 is partial pressure of oxygen in alveoli. PaO2 is partial pressure of oxygen dissolved in (arterial) blood. Partial pressure of a gas dissolved in a …
