A wrist oximeter is a medical device used to measure the oxygen saturation level in a person's blood. It is worn on the wrist like a watch and uses a non-invasive method to measure the amount of oxygen in the blood.
The device works by shining a light through the skin on the wrist and measuring the amount of light that is absorbed by the blood. The amount of light absorbed is directly related to the amount of oxygen in the blood. The oximeter then displays the oxygen saturation level as a percentage on its screen.
Wrist oximeters are commonly used in medical settings to monitor the oxygen saturation level of patients with respiratory problems, such as asthma, COPD, and pneumonia. They are also used to monitor the oxygen levels of patients during surgery or in critical care units.
In addition to medical settings, wrist oximeters can also be used by individuals to monitor their own oxygen levels, particularly for those with respiratory issues or sleep apnea. It is important to note, however, that wrist oximeters should not be used as a substitute for medical advice or treatment.
