Brief Summary

The aim of this study was to determine the effect of gel nail application on pulse oximetry measurements in healthy subjects. This study was planned as a prospective, self-controlled clinical research to determine the effect of gel nail application on SpO2 and pulse values in healthy people. The population of the study will consist of women who had gel nail application in a private beauty centre between July 2023 and July 2024. The minimum required sample size was calculated as 162 in G\*Power (3.1.9.2) programme (α=0.05 (two-way), 1-β=0.95). The data will be collected with the data collection form prepared in line with the literature.First, the age and smoking status of participants who meet the research criteria will be recorded on the data collection form. Then, the finger to which the gel nail polish will be applied and the control finger will be determined by drawing lots between the index fingers. Based on the result of this draw, gel nail polish will be applied to the left index finger of each participant, while the right index finger will be used as the control. Following the application of gel nail polish, SpO₂ and heart rate (HR) measurements will be obtained simultaneously from the left and right index fingers using pulse oximeters (POs). All measurements will be performed under standardized conditions: (1) participants will rest for at least 5 minutes before measurements, (2) their hands will be positioned at heart level, (3) ambient lighting and room temperature will be kept constant, and (4) participants will be instructed to remain still during measurements. These procedures will be applied consistently to all participants in order to minimize variability and enhance data reliability. The data obtained from the study will be analysed using SPSS (Statistical Package for Social Sciences) for Windows 26.0 software.
