Question
Chapter 6, Problem 1CAQ2
Summary Introduction
To review:
The oxygen transport studies that verified the patient’s PaO2 and SaO2 values were misleading in the given case.
Introduction:
SaO2 is defined as the amount of haemoglobin that is saturated with oxygen and PaO2 is defined as the pressure of oxygen in the arterial blood. The oxygen transport study gives us information about the total oxygen delivery (
Please refer to Clinical Application Case-1 for further information.
