How often should an SpO2 sensor be repositioned on a child?

The saturation of oxygen is vital to your body, however the readings depend based on the reason you need to read the levels. The most convention method is the 'finger' reader which reads the percentage of Sp02 present. Anything in the upwards of 96%+ is great and should be expected, but there is no definite 'repositioning' required as most units do not require calibration.
