Smart rings with a pulse oximeter to measure blood oxygen levels
Pulse oximeter (oxygen)
— a pulse oximeter is responsible for determining the level of oxygen saturation in the blood. Measurements using it are carried out using a non-invasive method, i.e. without punctures or other damage to the skin. Like most “medical” sensors in smart rings, the pulse oximeter is not ultra-precise and is not a full-fledged medical device, but it is quite capable of responding to a critical decrease in oxygen levels in the blood. The function can be useful both for certain diseases of the respiratory system and for completely healthy users (primarily climbers and balloonists).| pulse oximeter (oxygen) | clear | Save List |
