Reasons for Inaccurate Reading
When your blood perfusion level is low, the spo2 pulse oximeter might have a hard time registering an accurate reading;
We suggest that you warm your hands and fingers before taking the measurements(You can do this simply by rubbing your hands together);
Following that, please also ensure that you keep your hand still because any movement can cause the device to reset its reading;
Nail polish and false fingernails may also cause false readings.
