How to ensure measurement accuracy? We recommend the doctor's finger, middle and index fingers according to the position of the monitor. If the oxygen-saturated device and the heart are at the same level, the measurement result is optimal. If the movement is too fast, it will affect the accuracy. Try to stay still while waiting to read. Avoid manicure fingers and long claws that are used for reading. Your fingers should not get wet at all.
