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.
Sulfur dioxide (SO 2) is a colorless reactive gaseous air pollutant with a pungent odor. This gas can pose a threat to human health, animal health, and plant life.The primary sources of sulfur dioxide emissions are from fossil fuel combustion and natural volcanic activity. People with lung diseases, such as asthma, chronic bronchitis, and emphysema will generally experience more serious health effects at lower SO 2 levels. 2  Children are at higher risk from SO 2 exposure because they are more likely to have asthma, which may be aggravated by SO 2 exposure.
