Effect of Gel Nail Application on Pulse Oximetry Measurements in Healthy Individuals

Turkey (Türkiye)162 participantsStarted 2023-07-01

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
