Purpose: This study aimed to identify the position for the most accurate head-up cardiopulmonary resuscitation (CPR) by comparing saddle position CPR (SPCPR) and traditional CPR (TCPR). Methods: Sixty certified persons who completed a basic life support provider course between May 1 and June 21, 2019 were enrolled in the study. The participants were asked to perform 2 minutes of CPR, and the depth of chest compression, rate, position, full release, and hands off time were assessed. Accuracy was evaluated based on data collected from a smart phone application connected to the manikin via bluetooth and analyzed using frequency, percentage, t-test, analysis of variance and χ². Results: The accuracy of chest compression was statistically significantly higher for SPCPR, 63.03%[±8.75] for SPCPR and 55.50%[±10.17] for TCPR [t=3.074, p=.003]. The depth of chest compression was statistically significantly greater for SPCPR, 4.51cm[±0.45] for SPCPR and 4.16cm[±0.61] for TCPR [t=2.503, p=.015]. The rate of chest compression was statistically significantly higher for TCPR, 105/min[±10.79] for SPCPR and 111/min[±11.57] for TCPR [t=-2.008, p=.049]. Accuracy of position of chest compression was statistically significantly higher for SPCPR, 96.10%[±13.73] for SPCPR and 79.93%[±30.34] for TCPR [t=2.659, p=.011]. Accuracy of full release was higher with SPCPR, with 86.30%[±30.53] for SPCPR and 71.10%[±36.05] for TCPR, but the difference was not statistically significant [t=1.762, p=.083]. Conclusion: Saddle position CPR was found to be more accurate than TCPR in the performance of manual head-up CPR.
