Pulse oximeter is a non-invasive method of measuring oxygen saturation of hemoglobin by putting the transducer probe on skin. It measures the oxygen saturation in percentage and the normal value for it is 95 percent and values below 92 % are considered abnormal. The equipment also displays the heart rate normal range for which is 60-100 beats per minute. Pulse less than 60 can be noted in athletes and it is expected to rise in fever and other pathological conditions.
