Pulse oximeters measure oxygen saturation levels in the blood. This information can be used to help diagnose and treat conditions related to low oxygen levels, such as heart disease, stroke, and certain cancers. Pulse oximeters are also used to monitor patients during sleep.
Most patients should begin using a Pulse oximeters as part of their regular health care routine after they have had a cardiac event (such as a heart attack or stroke). Pulse oximeters can also be beneficial for monitoring patients during sleep. Patients who are at high risk for low oxygen levels, such as those with heart disease or cancer, should use a pulse oximeter regularly.

A pulse oximeter measures the amount of oxygen in your blood by sending short pulses of light through the blood vessels and measuring how long it takes for the light to reflect back from different parts of your body. The higher the oxygen level in your blood, the shorter the pulses will be and the more reflected light will be detected. This information is then converted into an estimate of your oxygen saturation level.
A pulse oximeter is a small, personal device used to measure the oxygen saturation in blood. It is typically used by people who have a heart condition, stroke, or pulmonary embolism. Pulse oximeters are also used to diagnose sleep apnea, hypoxemia (low oxygen levels), and other health conditions.
People who use a pulse oximeter need not be afraid of needles; the device uses a tiny amount of blood to measure oxygen levels. If you are having difficulty breathing and would like to assess your oxygen levels, a pulse oximeter may be the right tool for you.
