Can someone please explain the difference PO2 and PaO2?
2009年4月10日 · PaO2 is partial pressure of oxygen dissolved in (arterial) blood. Partial pressure of a gas dissolved in a liquid depends on the qualities of the liquid and the concentration of the gas. This is where the dissociation curve comes in - its the relationship between the pp and total content of O2 in the blood.

2008年7月10日 · PaO2 describes the amount of oxygen dissolved in arterial blood plasma. The measurement is given as a pressure value (mmHg). The measurement is given as a pressure value (mmHg). There is a relationship between the two numbers, which is described in the oxyhemoglobin dissociation curve.
SpO2 vs. SaO2 - Nursing Student Assistance - allnurses
Quick and dirty, your pao2 should be roughly 4-5x the % of oxygen you're breathing; normal pao2 is 80-100 if room air is around 20% oxygen. If you breathe 100% oxygen, your pao2 should measure around 400-500. If it doesn't, your lungs are doing a lousy job of gas exchange. Same with any other supplemental level.
When SpO2 values dont' match PaO2 - Cardiac Nursing - allnurses
2014年10月22日 · A smoker could have an SpO2 of 98% and be complaining of shortness of breath. The PaO2 may also come back low. A co-oximeter might measure the SaO2 at 85% and 10 - 13% COHb. The patient could also have a low hemoglobin in combination with the COHb. I prefer to print out various calculations associated with the blood gas such as content and A-a.
