Objective: This study aimed to propose an appropriate and effective cardiopulmonary resuscitation (CPR) method by comparing the differences in efficacy, convenience, and pain levels between the two-thumb compression and two-finger compression method for infant CPR by 1 person
Methods : This study was conducted on 45 paramedic students who had completed the basic CPR course. Subjects were randomized to perform either two-finger chest compression or two-thumb chest compression with two-hand wrapping for 8 minutes each on infant CPR mannequins. Total number of compressions, total compression depth, total compression speed, total number of rescue breaths, and mean total time of chest compression interruption were measured. After the experiment, a survey was performed to measure convenience and pain levels according to compression method. The collected data were analyzed for frequency, percentage, Wilcoxon sign-rank test, and Friedman test with SPSS 24.0 program; p<0.05 was deemed statistically significant for all tests.
Result
1) Of the 45 subjects, 27 (60%) were female. Average age of the subjects was 22.6 years. Twenty-four subjects (53.3%) had received CPR education ≥3 times and 19 subjects (42.2%) had received infant CPR education ≥2 times.
2) Total compression depth over 8 minutes was significantly deeper for two-thumb chest compression with two-hand wrapping (43.5±4.8 mm) than for two-finger chest compression (32.6±5.4 mm) (p<0.001).
3) In terms of compression depth measured at 1-minute intervals, compression depth with two-finger chest compression decreased from 38.3±4.23 mm to 29.0±6.79 mm, while compression depth with two-thumb chest compression with two-hand wrapping did not show a significant change from 43.7±4.12 mm to 43.4±5 mm.
4) According to the survey on basic CPR techniques, the majority of subjects answered that two-thumb compression with two-hand wrapping was the most comfortable technique for compression depth (29 subjects, 64.4%) as well as for location of chest compression (22 subjects, 48.9%). The majority of subjects (31 subjects, 68.9%) answered that two-finger compression resulted in the highest pain.
Conclusion: Comparison of CPR efficacy between two-thumb compression with two-hand wrapping and two-finger compression showed that two-thumb compression with two-hand wrapping was more effective in maintaining chest compression depth. Thus, this method would be useful in infant CPR by 1 person because it enables maintenance of appropriate compression depth, which is an important factor for high-quality CPR, without compromising chest compression speed and minimization of compression interruption.
