How to Measure Oxygen Saturation Oxygen saturation is measured in one of two ways: an arterial blood gas test (ABG or Sa02) or pulse oximetry (Sp02). ABG is usually only done in a hospital, while pulse oximetry can be done in other healthcare settings (like a provider's office) and ...
If you’ve had a checkup, a medical professional may have clipped a device to your finger to measure your oxygen saturation (SpO2) and pulse. Until last year, that was my only experience with such devices, but during the pandemic, I and many others purchased our own pulse oximeters to ...

Together they measure your oxygen saturation (SpO2) in your blood -- how much oxygen from your lungs your red blood cells pick up and transport to all of the other parts of your body. Low blood oxygen levels, or hypoxemia, have been linked to COVID-19 because the disease affects your...
How Is Blood Oxygen Level Measured? You measure blood oxygen, also called oxygen saturation, with apulse oximeter. It's a small device that clips to your finger (or another part of your body) and determines the ratio of red blood cells that are carrying oxygen to those that are empty. ...
Using a paediatric fingertip pulse oximeter on a baby can be a quick and non-invasive way to measure their oxygen saturation levels. Here are the steps to follow: Choose an appropriate pulse oximeter: Make sure to choose a paediatric finger pulse oximeter. These are usually smaller in size an...
A more common, non-invasive method is pulse oximetry. This process uses a pulse oximeter, a small device clipped onto an external body part like the finger, earlobe or toe. The device employs ultraviolet light to measure the oxygen in the capillaries, providing results quickly and painlessly....
