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.
The O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust as the exhaust exits the engine. Monitoring oxygen levels in the exhaust is a way of gauging the fuel mixture. It tells the computer if the fuel mixture is burning rich (less oxygen) or lean (more oxygen).ne of the key sensors in this system is the oxygen sensor. It's often referred to as the O2 sensor because O2 is the chemical formula for oxygen (oxygen atoms always travel in pairs, never alone).
