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 ...
The interpretation of oxygen saturation monitor or pulse oximeter readings is a comparison of test results to the normal expected range. Analyzing the results requires an understanding of how these machines work and what each number signifies. It's important to note the “normal range” used for ...
A pulse oximeter is a small and light device that looks like a clip. You attach it to a part of your body like the fingers, toes, or earlobes as a non-invasive way of measuring your oxygen saturation level. These devices can quickly detect even the slightest changes of oxygen levels in...
A pulse oximeter emits light that passes through your fingernail, skin, tissue, and blood to a sensor on the other side. The device measures how much light passed through without being absorbed by tissue and blood. It then uses that measurement to calculate how much oxygen is in your blood....
Bright red blood isoxygenated, while dark red blood has less oxygen, either because it's been delivering oxygen to your organs and muscles or it's not getting enough oxygen from your lungs. If you want to dig into exactly how pulse oximeters work, check out thisarticle publishedin the Res...
Generally, an HSAT measures breathing, snoring, pulse, and blood oxygen levels. Unlike a PSG, an HSAT does not usually measure brain waves, muscle activity, or heart activity beyond the pulse taken with a pulse oximeter. That means electrodes are not usually part of an HSAT. ...

Conventional medical pulse oximeter employs the transmissive pulse oximetry method where peripheral parts of the body like ear lobe, fingertips and toes in babies are used. The most popular invol...
Note that WHOOP 4.0 includes a pulse oximeter that uses red and infrared light, both of which are less prone to interference from skin pigments or tattoos. However, WHOOP only uses the pulse oximeter for sleep tracking, because it’s prone to interference by movement. ...
the penetrating or reflected light intensity changes. In this way, the pulse can be detected. Today, such a PPG sensor is usually installed not only in pulse oximeters (e.g. finger clips, in-ear sensors) but also in fitness wristbands. In pulse oximetry, the functionaloxygen saturation(SpO2...
