The oximeter is a medical device used to measure the blood oxygen saturation of the body. Oxygen saturation is the percentage of oxygen in the blood. The normal value is 95% to 100%, and if it falls below 90% it may cause hypoxia. Oximeters typically use an optical sensor to measure oxygen saturation and can be used to monitor respiratory diseases such as COPD, asthma, and emphysema
