Our body needs around 400 litres of oxygen (O2) every day. Oxygen keeps our cells alive and functional. Hemoglobin inside the blood are the transporter of the oxygen and bloodstream are supplying the organs.
Oxygen saturation of the blood can be measured without drawing the blood. The colour of the blood allows conclusions to be drawn about the oxygen saturation:
The oxygen saturation provides information about the percentage of hemoglobin in the arterial blood that is loaded with oxygen. It is therefore an important parameter for assessing respiratory function.
The following symptoms occur more frequently in people with a low oxygen saturation level:
Oximeters are equipped with the photoelectric fingertip sensor to diagnose which capture the oxygen content (saturation) in the arteries (Pulse rate and perfusion index).
Three factors are measured:
1- SpO2:
Amount of oxyhemoglobin which expressed as a percentage of functional haemoglobin. (Adults: 94% to 99%, infants: 85% to 100%)
2- PR:
Frequency of heartbeat (heart rate or pulse rate). (Adults: 60 bpm to 100 bpm, infants: 120 bpm to 150 bpm)
3- PI:
Ratio of pulsating blood flow to non-pulsating static blood in peripheral perfusion. (Range: 0.02% to 20%)
Place your finger in the test chamber with your fingertips and press the button! You will get the results in approximately 8-10 seconds.
