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.
All in all, the low SaO2 of the typical OSA patient is the biggest problem we face. Low SaO2 effects the entire body. In the lab they do a baseline study of the patients while awake. The baseline SaO2 is what they try to hit during the sleep study.In most OSA patients baseline is over 95%. I severe cases where the OSA has already had detrimental effects on the body the baseline may be in the high 80% area.I hope you get the general idea i could write volumes on the effects low O2 has on the body.ll in all, the low SaO2 of the typical OSA patient is the biggest problem we face.
