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 October 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 gel nail 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.

Outcome Measures

Primary Outcomes (2)

  • SpO2 value

    Data collection form: After the gel nail was applied to the middle finger of the left hand, SpO2 values were measured and recorded by pulse oximetry from the left hand middle finger and little finger of the participant.

    3 months

  • Pulse value

    Data collection form: After the gel nail was applied to the middle finger of the left hand, pulse values were measured and recorded by pulse oximetry from the left hand middle finger and little finger of the participant.

EXPERIMENTAL AND CONTROL GROUP

OTHER

Participants who meet the inclusion criteria of the study will be informed about the research by the researchers and will be included in the study on a voluntary basis and their written permissions 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 experimental group and the little finger will be the control group. After the gel nail is applied to the middle finger of the left hand, SpO2 and pulse values will be measured by pulse oximetry from the left hand middle finger and little finger of the participant and recorded in the data form. At the end of the study, SpO2 and pulse values before and after the gel nail application will be compared.

Other: Gel nail application

Interventions

The middle finger of the left hand of each participant will be the experimental group and the little finger will be the control group. After the gel nail is applied to the middle finger of the left hand, SpO2 and pulse values will be measured by pulse oximetry from the left hand middle finger and little finger of the participant
