What is a pulse oximeter?
A finger pulse oximeter uses light-based sensing to estimate oxygen saturation and pulse rate. Readings should be interpreted in context, especially when symptoms or chronic respiratory conditions are present.
Pulse oximeter uses
Common home uses include spot-checking SpO2 and pulse rate when advised by a healthcare professional. Device accuracy, fit, circulation, movement and other factors can affect readings.
