Q. How should we take a reading with finger pulse oximeter?

Answer

Pulse oximetry is useful in both inpatient and outpatient settings. At home, people should take a reading with a finger pulse oximeter. But before, you need to remove any jewellery or fingernail polish on finger. You need to ensure that your hand is warm, relaxed, and below heart level. Now you should place the device on your finger, earlobe, or toe and keep it on for as long as needed to monitor your pulse and oxygen saturation.
