What is Pulse Oximetry?
Friday, 28 June 2019 | Paul
We all know that the body and our organs need oxygen to survive and function. Once our lungs have filtered the oxygen that we breathe in, it is distributed into the blood via the haemoglobin proteins in red blood cells. This is how the body supplies oxygen to our organs.
However, what if they aren’t getting enough oxygen, and how do we measure this? That’s where pulse oximetry comes in.
How Does it Work?
Put simply: pulse oximetry is a noninvasive method of measuring the oxygen saturation levels in our blood. Pulse oximetry measures the percentage of oxygen contained in the red blood cells (SpO2), which should be between 95% and 100% for appropriate levels of functioning. This is considered low if the level of oxygen falls below 90% and can cause serious problems, so supplemental oxygen may be required.
How Do You Test This?
Pulse oximeters are small devices which the finger is slipped inside. The device then shines red and infared light through your finger to measure how much of this is permitted to transfer through, as this depends on how saturated with oxygen your blood is.
Why Are Pulse Oximeters Important?
Necessary equipment for individuals receiving supplemental oxygen, pulse oximeters allow monitoring of how well this is being received. However, these devices can also deliver insights into how the body reacts to various exercises and strenuous activity to allow an invaluable way of monitoring your health.
