To give you a better understanding of PowerShell, we should first define what a shell is. No, we're not talking about a turtle's shell. :) In computer science, a shell is a user interface that gives you access to various services of an operating system.
SaO2 can be measured either by ABG analysis or by pulse oximetry. SaO2 refers to the amount of oxygen bound to hemoglobin in arterial blood. SpO2 simply means that the SaO2 was measured using pulse oximetry.aO2 is an invasive measure of the % of Oxyhemoglobin (oxygen saturated hemoglobin) in the blood using lab tests on arterial blood. SpO2 noninvasive measure the % of saturated hemoglobin in the capillary bed and does not identify what is saturating the hemaglobin.
CaO2 or âOxygen Contentâ gives a definite amount of ALL the oxygen in the blood. It is the only method that takes into account how much hemoglobin is actually present in the body and uses the PaO2 and SaO2 values to get the amount of oxygen. It uses the units âml O2/dlâ (milliliters of oxygen per deciliter of blood).
