Purpose : This study is equivalence experiment performed to test practice effects between experimental group from both left and right direction of mannequin and control group having practice from only right direction in cardiopulmonary resuscitation education. Methods : Subject of the research were total 71 elementary and middle school teachers in J province who had not experience to have cardiopulmonary resuscitation. They were divided into experimental group of 35 participants who practiced cardiopulmonary resuscitation from both right and left direction of mannequin on Dec. 27, 2009 and control group of 36 participants who performed cardiopulmonary resuscitation from only right direction of mannequin on Dec. 28, 2009. Collected data were analyzed by SPSS/PC+(version 14.0). Results : 1. There was no statistically significant difference by sex among general characteristics of the subjects. 2. According to the quality of chest compression performed from the right direction of mannequin, experimental group showed better results in proper depth (time), insufficient depth (time), too lowered compression position (time) and inexact position (time) than control group(p<.05). In the quality of chest compression from the left side of mannequin, experimental group performed better results in proper depth (time), insufficient depth (time), inexact compression position (time) and mean chest compression depth(mm) than control group(p<.05) and also in more left-centered compression position (time) than control group(p<.001). 3. The quality of chest compression by experimental group, the right side of mannequin was superior in proper depth (time) to the left side of mannequin (p<.001) and showed better results in insufficient depth (time) and chest compression/recoil rate (p<.05). According to the quality of chest compression by control group, the right side of mannequin showed superior results in proper depth (time), insufficient depth (time), too left-centered compression position (time) and mean chest compression depth (mm) (p<.05) to the left side of mannequin. Conclusion : The group having practice from both right and left sides of mannequin was superior in the quality of chest compression to the group having practice from only right side of mannequin. How to practice cardiopulmonary resuscitation from both right and left sides of mannequin can be recommended and practice from left side of mannequin is also useful.

Objective: The purpose of this study was to investigate the effect of levels of education on ground reaction force and center of pressure parameters during chest compression resuscitation. Method: Twenty male university students were divided into two groups; certified group (CG, n=10) and non-certified group (NCG, n=10). Two force plates were used to measure ground reaction force and center of pressure parameters during 30 times (three trials) chest compression resuscitation. Independent t-tests were used to compare ground reaction force and center of pressure parameters between two groups. An alpha level of 0.05 was used in all tests. Results: All chest-compression time parameters (total time, 1 systolic time, and diastolic time) in CG were significantly shorter than those in NCG (p<.05). Fy of the diastolic and Fz of the systolic in CG revealed significantly the larger GRF values and Fy of the systolic in CG showed significantly the smaller GRF value (p<.05). The standard deviation of Fz of the systolic and diastolic within the subject during 30 times chest-compression resuscitation revealed significantly the smaller values in CG (p<.05). Conclusion: First, CG performed chest compressions efficiently at an appropriate rate compared to NCG. Second, CG showed lower Fx and Fy values in both the mediolateral and anteroposterior axes compared to NCG, which reduced unnecessary chest-compression force consumption and minimized the movement in patients with cardiac arrest. Third, CG showed high Fz value of the systolic and low Fz value of the diastolic. Based on this, chest compression resuscitation was performed to increase the survival rate of cardiac arrest patients.

Purpose: The purpose of this study is to predict a reasonable direction to design a pertinent educational program in the future by evaluating an adult CPR(Cardiopulmonary Resuscitation) skill performed by EMTs engaged in fire services organization and comparing the CPR success rate of factors as like a duty place and licensed year. Methods: We studied CPR skill by the use of a CPR manikin(Skillmeter Resusci Annie, Laerdal company). The study population consisted of 320 EMTs. Every EMT performed four cycle after investigating the manikin for 2 minutes. We regarded chest compression with 100 times in a minute as the 100% success rate. We analysed the skill of chest compression, ventilation and chest compression times success rate by the records printed in the CPR paper. Results: The average success rate of chest compression was 59.42$\pm$29.26% and ventilation 49.22$\pm$29.65%. The success rate of manual CPR was different between chest compression and ventilation. Also the success rate of chest compression times was high relatively as a 87.32$\pm$9.14%(p=0.000). For the CPR skill, ventilation was lowest as 49.22%. The factors such as duty place and licensed year did not influence the CPR success rate (p>0.001). Conclusion: We could have conclusion that CPR training should be shared more time in ventilation than in chest compression. Also we could reach to a conclusion that it is important to increase the times of CPR training for improving the accuracy of CPR and that the continuing education of CPR training frequency might be more than four times in a year.

In this paper, the researcher investigated whether strengthening the back muscles affects the quality of chest compressions during cardiopulmonary resuscitation by university students. A total of 50 students majoring in healthcare were included from September 2018 to November. The participants performed chest compressions during cardiopulmonary resuscitation (CPR) for 2 min after back muscle strength was measured. Then, after adequate rest, the participants repeated the back muscle strength measurements and chest compressions after taping the erector spinae muscle. The paired t-test was performed to analyze changes in chest compression quality after taping. As results, taping enhanced back muscle strength and positively affected the depth of chest compressions and the compression to recoil ratio. Taping also increased confidence and lowered fatigability during chest compressions, so the participants preferred being taped while performing chest compressions. Based on these results, taping could help emergency room medical personnel specialized in CPR to enhance the quality of CPR and relieve back pain and fatigability by strengthening the back muscles.

In this paper, we propose a the effects of new chest compressions in the implementation of chest compressions during infant cardiopulmonary resuscitation, and to provide basic data for high-quality CPR. On March 12, 2019, the research target used the SPSS 22.0 Version as an experimental study using randomized cross-design of 30 emergency medical services students who completed BLS Health Care-provider. The study also showed significant differences in chest depth and average rate of pressure($34.61{\pm}1.29$, $39.40{\pm}1.08$, <0.001, $105.46{\pm}4.23$, $107{\pm}3.84$, <0.001) depending on chest compressions. There was also a significant difference in the convenience and degree of pain of chest compressions(<0.001). In addition, new chest compressions appeared close to vertical and showed statistically significant differences(p<.001). Based on the results of this study, we can see that the accuracy of the new chest compressions during infant cardiopulmonary resuscitation is increased, and the depth of chest compressions is improved, improving the quality index of chest compressions. However, it will be necessary to further study the use of the new chest compressions to identify the potential for clinical use.
