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.
2. Examine the PCO2 number on your report. This number is the amount of carbon dioxide in the blood. It is the respiratory component in acid-base balance. It is measured in millimeters of mercury (mmHg). The normal level for PCO2 is between 35 to 45 mmHg.1  The condition of respiratory alkalosis is present if the PCO2 number is below 35 mmHg. 2  This means there is too little carbon dioxide in the blood. 3  A person with this condition can be breathing very fast (hyperventilating).he normal level for PCO2 is between 35 to 45 mmHg. 1  The condition of respiratory alkalosis is present if the PCO2 number is below 35 mmHg. 2  The condition of respiratory acidosis is present if the PCO2 number is above 45 mmHg.
