Clinical use of non-invasive method for determining oxygen saturation: ear oximetry.
Oxygen saturation can be estimated by measuring the absorption properties of the arterialized blood perfusing the ear. Simultaneous determination of oxygen saturation by blood gas and ear oximetry showed no statistical difference. This non-invasive method allows rapid and accurate monitoring of the oxygenation status of patients with respiratory insufficiency.
