A pulse oximeter measures the amount of oxygen in blood by shining a light through the tip of a person's finger. This piece of equipment is part of the standard repertoire of medical tools carried by paramedics and other first responders. Otana wondered whether wearing nail polish or artificial nails might change the accuracy of pulse oximeter readings.
Otana took blood oxygen readings of 23 volunteers wearing six colors of nail polish and the same colors of artificial nails using two different brands of pulse oximeters. She also took readings using 27 brands of various colors of nail polish on the same volunteer. She found that nail polish and artificial nails didn't significantly change pulse oximeter readings.
