Pulse Oximeters in Vadodara Pulse oximeters are medical devices that are used to measure the oxygen saturation level in a person's blood. The device is placed on a person's fingertip or earlobe and uses light to measure the amount of oxygen in the blood. Pulse oximeters work by shining a light through the skin to the blood vessels underneath. The device measures how much light is absorbed by the blood, which can be used to calculate the oxygen saturation level. A healthy person should have a blood oxygen saturation level of 95% or higher. Pulse oximeters are often used in hospitals and clinics to monitor patients with respiratory problems, such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. They can also be used to monitor people with heart conditions, sleep apnea, and other medical conditions.
