Abstract

Background: Pulse oximetry is a vital non-invasive method for monitoring oxygen saturation (SpO2). However, factors such as nail polish and artificial nails can potentially affect accuracy. Gel-based manicures, widely used for their durability, may interfere with SpO2 readings. This study evaluates the impact of gel manicures on pulse oximetry accuracy. Methods: A prospective observational study was conducted in Akash institutes of Medical Sciences, including 25 healthy volunteers with and without gel manicures. SpO2 was measured on gel-painted and unpainted nails using a standard pulse oximeter. A comparison was made between the two readings using paired t-tests. Results: A statistically significant difference (p < 0.05) was observed in SpO2 readings between gel-painted and unpainted nails. The mean SpO2 recorded from gel-painted nails was lower than that from unpainted nails. Conclusion: Gel-based manicures significantly impact pulse oximetry readings, potentially leading to false hypoxia alarms. Clinicians should consider alternative measurement sites (earlobe, forehead) in patients with gel manicures.
