An oximeter is a medical device that measures the oxygen saturation of your blood. It is a small, lightweight device that clips onto your fingertip and shines a light through your finger. The light is absorbed by the oxygen in your blood, and the amount of light that is absorbed is measured by the oximeter. This information is then used to calculate your oxygen saturation.
Oxygen saturation is a measure of how much oxygen is in your blood. It is important to have a healthy oxygen saturation level because oxygen is essential for life. If your oxygen saturation level is too low, you may experience symptoms such as shortness of breath, fatigue, and confusion. In severe cases, low oxygen saturation levels can lead to organ damage and death.
