Pulse oximetry is a test that measures oxygen levels in the blood using a small, clip-like device called a pulse oximeter. When you breathe, your lungs absorb oxygen and transport it to your bloodstream. This oxygen-rich blood is delivered to your heart, which then circulates it throughout your body. If your blood oxygen level (oxygen saturation) is too low, your body may struggle to function correctly. It might be damaging to your essential organs. Pulse oximetry is a rapid and painless way to determine whether your oxygen level is too low. Treatment of low blood oxygen levels as soon as possible may help you prevent serious complications.
Pulse oximetry is used to measure the amount of oxygen in your blood. The test may be performed at a clinic, a hospital, or even in your own home. If you have a significant and/or persistent lung condition, an at-home pulse oximeter may be beneficial.Used to detect
