There are many things in this world that cause a person to suffer and be afraid, but the worst thing is to have a sick child.
Some of these feelings are compared to the hopelessness parents feel when they see their child in pain or know they are suffering.
Everything will be done to help this child relax and feel good, and it is evident that the child will feel more at home than in the hospital.
Because of this, nowadays there are portable devices to monitor certain things, such as a SpO2 Simulator (Pulse Oximeter Tester), which monitors the oxygen levels in red blood cells.
It is used to detect certain things like heart defects and to check the flow of oxygenated blood throughout the body. The process is non-invasive and completely painless.
The results are recorded and then analyzed by the doctor to look for problems and determine the next course of action.
This method is called pulse oximetry and has been used for many years with excellent results. Now comes the technical part, which sounds a lot more confusing than it really is.
Prior to pulse oximetry, arterial oxygen saturation (SaO2) was measured directly by blood gas analysis. If it is now measured indirectly with pulse oximetry, it is called SpO2.
Pulse oximetry uses sensors (sometimes called probes) and monitors that analyze data and display the results.
