The purpose of this study was to determine the effect of different colour nail polishes and henna on the measurement of oxygen saturation and the differences among the measurements of three pulse oximetry devices.
33 healthy females with a mean age of 19±1.0 years and no complaints or known disease were included into the study. All the participants applied henna to one of their fingers a day before the study. Just before the study, one finger was left empty as control and the other fingers were dyed using various colours of nail polish (red, blue, beige, purple, brown, white, pink, green, colourless polish, light blue, light green and yellow). There were more than eight colour nail polishes and some fingers were used for the other colours after being completely cleaned. The same brand nail polishes were used for the study. Oxygen saturation measurements were done using three different pulse oximetry devices (device I, II, III) from the control, different colour nail polished and henna applied fingers. The measurements of different devices, different colour nail polishes, henna and control were statistically compared.
The mean saturations obtained from blue, beige, purple and white nail polished fingers were significantly lower than those of control and the other coloured fingers. In addition, the mean measurement of device II was significantly lower than those of other devices.
The results suggest that blue, beige, purple and white nail polished fingers might cause pulse oximetry devices to make incorrect measurements.
本研究旨在确定不同颜色指甲油和指甲花对血氧饱和度测量的影响，以及三种脉搏血氧仪测量结果的差异。
纳入 33 名年龄在 19±1.0 岁之间的健康女性，均无任何不适或已知疾病。所有参与者在研究前一天在一只手指上涂指甲花。在研究开始前，一只手指为空手指作为对照，其他手指则涂上各种颜色的指甲油（红、蓝、米色、紫、棕、白、粉、绿、无色指甲油、浅蓝、浅绿和黄）。有八种以上的彩色指甲油，在完全清洁后，一些手指会用于其他颜色。研究中使用了同一品牌的指甲油。使用三种不同的脉搏血氧仪（仪器 I、II、III）从对照、不同颜色指甲油和指甲花涂抹的手指上测量血氧饱和度。统计比较了不同仪器、不同颜色指甲油、指甲花和对照的测量结果。
涂有蓝色、米色、紫色和白色指甲油的手指的平均饱和度明显低于对照手指和其他颜色的手指。此外，仪器 II 的平均测量值明显低于其他仪器。
结果表明，蓝色、米色、紫色和白色指甲油可能会导致脉搏血氧仪测量结果不准确。
