Q: What might make pulse oximeter readings less accurate?

Pulse oximeters can have falsely low readings if a person has circulatory issues with poor blood flow to the extremities, such as very cold hands, intrinsic vascular disease or Raynaud's phenomenon.

In addition, fake nails or certain darkly colored nail polish, such as black or blue, can distort the readings.

So we recommend that people measure at least one finger per hand to confirm the number.
