The nurse will perform pulse oximetry to monitor the effectiveness of the oxygen therapy ordered for the client.
<h3>What is pulse oximetry?</h3>
The oxygen saturation level of your blood can be measured with a non-invasive procedure called pulse oximetry.
It can quickly identify even minute variations in oxygen levels. These levels demonstrate how well blood transports oxygen to your arms and legs, which are the extremities that are farthest from your heart. It looks like a little clip and is called a pulse oximeter. It fastens to a body component, usually a finger.
Pulse oximetry is helpful for postoperative patients, monitoring individuals at risk for hypoxia, titrating oxygen therapy, and monitoring patients receiving oxygen therapy.
