The Secure Shell protocol version 2, or SSH2, specifies how a client can connect securely to an SSH server, and then use the resulting secure link to access the server's resources.Among other things, the client can run programs; transfer files; and forward other TCP/IP connections over the secure link.he SSH2 protocol is a descendant of the SSH v1.x series of protocols. SSH version 2 is standardized at IETF, and the vast majority SSH implementations now support SSH version 2.
Edit: SpO2 is the Saturation (peripheral) of Haemoglobin with Oxygen, expressed as a percentage ration compared to fully saturated Haemoglobin (Hb).i.e. when the Haemoglobin (the main oxygen carrying component of blood, found in red blood cells) is fully loaded with oxygen, then is it 100% saturated.t is SpO2, because this is normally measured by placing a probe on the finger which shines red light of two different types through the finger, and a calculation is carried out based on how much of each type of light is absorbed, which tells us how much the Hb is loaded up or saturated.
