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.
AS2 (Applicability Statement 2) is a specification about how to transport data securely and reliably over the Internet. Security is achieved by using digital certificates and encryption. Files are encoded as attachments in a standardized S/MIME message (an AS2 message). 2  AS2 messages are always sent using the HTTP or HTTPS protocol (Secure Sockets Layer â also known as SSL â is implied by HTTPS) and usually use the POST method (use of GET is rare).
