Saturation – Nail Polish and Two Different Devices

Abstract

Objective: Finger oxygen saturation monitoring with a non-invasive method is an important patient follow-up method that should be performed in the emergency room and peroperative period. The presence of nail polish is generally undesirable. This study was planned to evaluate the effect of nail polish on peripheral oxygen saturation and perfusion index. Materials and Methods: This study was conducted prospectively on 80 non-smoking healthy volunteers, aged 18 years and over in the 3rd Level University Hospital Emergency Department. Oxygen saturation value and perfusion index value in finger probe and perfusion index device were measured and recorded by applying dark blue nail polish, which affects oxygen saturation the most and shows the greatest difference in spectrophotometer absorbance. Results: The mean SPO2 level of the nail polish-free group with the probe was 1.48 units higher than the nail polish group. SPO2 level measured with PI was 1.18 units higher. The mean PI level of the nail polish-free group was 0.51 units lower than the group with nail polish. (p
