The Effect of Nail Polish on Pulse Oximetry Measurements in Female Volunteers

This cross-sectional study was performed from 01.03.2020 till 11.03.2020 and included 169 healthy female students of medical professions. Each participant rested for 5 minutesbefore collecting measurements. Oxygen saturation was measured with ACCURO ® pulse oximeter on the index right finger and on the right earlobe, using proper finger andearlobe sensors. The sensor probe was placed directly on the center of the polished nail and earlobe. In case of having any jewelry in the earlobe, participants were asked toremove it before gathering measurements. The colors were classified using participants’ declaration. SpO2 was recorded after observing an effective signal for at least of 5seconds.
