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.
Carbon Dioxide (C02) is essentially a waste product of the body but is important as a hameostatic feedback mechanism. The level of C02 in the blood is the most important influence on the regulation of ventilation. The blood level of C02 acts directly on the respiratory centres in the medulla and is a major influence on cerebroâspinal fluid pH.
