Effect of Shellac Nail Polish Application on Pulse Oximetry Measurements in Healthy Individuals

Study Overview
=================
Brief Summary
-----------------
The aim of this study was to determine the effect of shellac nail polish application on pulse oximetry measurements in healthy subjects. This study was planned as a prospective, self-controlled clinical research to determine the effect of shellac nail polish application on SpO2 and pulse values in healthy people. The population of the study will consist of women who had shellac nail polish application in a private beauty centre between June 2023 and December 2023. 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. Firstly, the personal information of the participants will be recorded in the data collection form. The middle finger of the left hand of each participant will be the treatment group and the little finger will be the control group. After the shellac nail polish is applied to the middle finger of the left hand, SpO2 and pulse values will be measured simultaneously with a pulse oximeter from the left hand middle finger and little finger of the participant and recorded on the data form. The data obtained from the study will be analysed using SPSS (Statistical Package for Social Sciences) for Windows 26.0 software.

The data will be collected with the data collection form prepared in line with the literature. On this form, the age of the individual, the color of the shellac nail, smoking status, and the SpO2 and pulse values measured by pulse oximetry from the little and middle finger will be recorded. SpO2 and pulse rates will be measured with a calibrated Jumper pulse oximeter. Since the shellac nail and non-shellac nail will be measured at the same time, two of the same brand pulse oximeter devices will be provided. Volunteers who meet the inclusion criteria of the research will be informed about the research and will be included in the research on a voluntary basis and their written consent will be obtained. Firstly, the personal information of the participants will be recorded in the data collection form. The middle finger of the left hand of each participant will be the treatment group and the little finger will be the control group. After the shellac nail polish is applied to the middle finger of the left hand, SpO2 and pulse values will be measured simultaneously with a pulse oximeter from the left hand middle finger and little finger of the participant and recorded on the data form. The data obtained from the study will be analysed using SPSS (Statistical Package for Social Sciences) for Windows 26.0 software. Mean and standard deviation will be used in the evaluation of the data. Statistical significance will be accepted as p<0.05 (95% confidence interval).
