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.
Pulse oximetry can be a useful aid in decision-making, but is not a substitute for a clinical assessment, nor sufficient for diagnosis by itself. Arterial blood gas measurements, obtained by arterial puncture, remain the gold standard for measurement of oxygen saturation. A personal finger pulse ...
The measurement of oxygen saturation provides conclusions about the function of the lungs. By determining the saturation of the venous blood, the blood flow, oxygen uptake as well as metabolic activity of the tissue can be assessed. Peripheral oxygen saturation is also used to calculate arterial ox...

The Blood Oxygen app for Apple Watch measures your blood oxygen level throughout the day as long as you have background measurements turned on. But if you want to take an on-demand measurement, you can do so manually at any time.
OXYGEN in the bloodBLAND-Altman plotBONFERRONI correctionSTANDARD deviationsHUMAN skin colorPulse oximeters are widely used in hospitals and homes for measurement of blood oxygen saturation level (SpO2) and heart rate (HR). Concern has been raised regarding a possible bias in obtaining p...
This function enabled the measurement of localized tissue oxygenation when the pulsatile arterial blood signal of PPG was low. In another study, Han et al. designed an organic ambient light oximeter (ALO) for the measurement of PPG and SpO2 from the index finger (Fig. 6c) (Han et al., ...
The sensors that measure oxygen level in the blood on the Apple Watch are highly sensitive and the reading will fail even if there's minor movement. If you're frequently getting an "Unsuccessful Measurement" warning, make sure to follow these steps. ...
