Abstract:
Objective To evaluate the effects of nail polish on measurement of pulse oxygen saturation (SpO2) by different brands of monitors in healthy volunteers.Methods Twenty healthy female volunteers were enrolled in the study.Nine fingers of each volunteer were chosen randomly,8 nails were painted 8 different colors (transparent color,red,yellow,green,blue,purple,black,white),respectively,and the left 1 nail served as blank control.SpO2 and pulse rate (PR) were measured using TuffSat Handheld Oximeter (GE) and MP70 (Philip) and PM-9800 (Mindray) monitors.SpO2 of the 9 nails monitored and the response time for SpO2 and PR were recorded.Results (1) Compared with blank control,when MP70 monitor was used,no significant change was found in each color-induced effect on the value of SpO2 obtained (P ＞ 0.05),and blue prolonged the response time for PR and SpO2 (P ＜ 0.05) ;When PM-9800 monitor was used,black could decrease the value of SpO2 measured (P ＜ 0.05),and no significant change was found in each color-induced effect on the response time for SpO2 and PR (P ＞ 0.05) ; when TuffSat Handheld Oximeter was used,green and blue could decrease the value of SpO2 monitored,and the value of SpO2 obtained was significantly lower when blue was used (P ＜ 0.05).Black,blue,purple and white could sequentially prolong the response time for PR (P ＜ 0.05),and no significant change was found in each color-induced effect on the response time for SpO2 (P ＞ 0.05).(2) For green and blue nail polish,the value of SpO2 measured with TuffSat Handheld Oximeter was significantly lower than that measured with MP70 and PM-9800 monitors(P ＜ 0.05) ; for red,yellow and green nail polish,the response time for PR obtained with TuffSat Handheld Oximeter was significantly shorter than that obtained with MP70 and PM-9800 monitors (P ＜0.05) ; for blank control group and 8 colors of nail polish,the response time for SpO2 measured with TuffSat Handheld Oximeter was significantly shorter than that measured with MP70 and PM-9800 monitors (P ＜ 0.05).For black nail polish,the value of SpO2 measured with PM-9800 monitors was significantly lower than that measured with MP70 and TuffSat Handheld Oximeter(P ＜ 0.05).Conclusion The ability for nail polish recognition and identification is different for each monitor and the color of nail polish can exert obvious effect on the value and response time for SpO2 obtained.The results of this study shows that blue nail polish-induced effect on the value of SpO2 obtained with TuffSat Handheld Oximeter is obvious,and MP70 monitor is the most stable instrument and TuffSat Handheld Oximeter is the most sensitive instrument in obtaining the value of SpO2.
