Brief Summary
In clinical practice discrepancies between overnight SpO2 recordings performed by 2 devices used simultaneously are regularly observed. However, this has not been systematically studied or quantified....
Detailed Description
Pulse oximetry estimates oxygen saturation in the arterial blood by trans-illuminating a translucent tissue (usually a fingertip, or an ear lobe) with light-emitting diodes at 2 specific wavelengths. ...
