Apr 10, 2009 · Hi all, I can't understand what is the difference between PO2 and Pa02. I know that PaO2 is the partial pressure of oxygen in blood. PO2 is partial pressure of Oxygen. Are they …

Oxygen partial pressure (paO2) and saturation (saO2) are 2 different things - read about the difference. Saturation can be measure directly/invasively (saO2) or indirectly/peripherally (spO2).

Jul 10, 2008 · PaO2 stands for the partial pressure of O2 in arterial blood, measured in mmHg. SaO2 is the arterial O2 saturation.

Oct 22, 2014 · Can someone please help me understand how an SpO2 value can be 95 while the PaO2 reads as low as 40 to 60. I know SpO2 is Hgb saturation% and SaO2 is O2 pressur...

PaO2: partial pressure of oxygen PaCO2: partial pressure of carbon dioxide HCO3-: concentration of bicarbonate SaO2: arterial oxygen saturation Base excess (BE): excess or …

May 13, 2007 · I am struggling with the difference/significance of PaO2 and SaO2 for my final next week. Does anyone know of a website that has REALLY basic information that m...

May 13, 2014 · While a PaO2 of 75 torr isn't too bad at all, a SAT of 75% is heading for the undertaker unless dealt with. Here's my very favorite ABG of all time: pH = 7.11, PaO2 = 136, …

Mar 1, 2021 · A normal PaO2 is 80-100 torr on room air. As a rough rule of thumb, PaO2 should be about 4-5 times the fraction of inspired oxygen (FIO2), where room air is about 21% or …

Mar 6, 2009 · Ok guys, I need some help with the alveolar air equation: I know it goes something like PAO2 = PIO2 - (PACO2/R) + F. Scenario is: pt breathing room air @ sea level, PaO2 = …

Oct 27, 2013 · You have a PaO2 appropriate for oxygen of 1 - 2 L in a COPD patient but he is obviously struggling since there is a pH of 7.42. True COPD patients who are retainers rarely if …
