Purpose : The purpose of this study was to investigate the variation of elapsed time in the cardiopulmonary resuscitation (CPR) quality and the fatigue in continuous CPR by single rescuer. This study will provide basic data about the time for the alternation of the CPR providers. Methods : The volunteer students having healthcare provider certification were recruited from the department of emergency medical service. The students performed 30:2 CPR for 20 minutes, and the data were recorded and analyzed. Metrics were based on the 2010 American Heart Association (AHA) Guidelines, and the CPR continued without any feedback. Results : Among the indicators of CPR, the accuracy and the depth of chest compressions decreased after about 5.3 minutes, and the rate increased approximately after 6.8 minutes. Changes in clinical indicators appeared, and fatigue increased after about 3 minutes. According to the increase in fatigue level, the changes in the CPR indicators and clinical indicators showed up, and these results proved to be statistically significant. However, there were no associations among the time, fatigue, and gender. Conclusion : Even though the times of changes in the indicators appeared differently, the times of changes in fatigue and CPR quality were able to be confirmed.

Objectives : The purpose of this study is to investigate the knowledge and attitude toward cardiopulmonary resuscitation(CPR) in some dental hygienists. Methods : A self-reported questionnaire was filled out by 207 dental hygienists in Gwangju from February to March, 2014. The questionnaire consisted of knowledge and attitude toward CPR dental hygienists. The data were analyzed using IBM SPSS 19.0 program for chi-square test, independent t-test, one-way ANOVA and multiple regression analysis. Results : Dental hygienists having basic life support(BLS) provider accounted for 16.9%. CPR knowledge was 8.40 and attitude was 3.59 points. There were positive correlations between CPR knowledge and attitude including education, performance, and confidence(r=.231, r=.207, r=.377). In the regression analysis, attitude toward CPR confidence were positively associated with BLS provider certificate within two years. Conclusions : Dental hygienists had low level of knowledge and confidence toward CPR. It is important to educate BLS provider course to the dental hygienists.

Purpose : The aim of the study is to compare the effect of cardiopulmonary resuscitation (CPR) with voice and CPR without voice by one rescuer. Methods : Subjects were 26 students in C University who had basic life support certificate for Healthcare Provider. They performed 30:2 CPR for 6 minutes by two groups of CPR with voice and CPR without voice by one rescuer from August 14 to 16, 2012. They performed CPR with Resusci Anne SkillReporter$^{TM}$ and Laerdal PC SkillReporting System Ver. 2.4.1(Laerdal Medical, Norway and recored voice using TES-1350A(TES Electrical Electronic Corp, Taiwan). Between each experiment, 1 day of rest was given, providing enough time to recover from the fatigue of CPR. Results : The depth, rate of chest compression, and ventilation volume were not affected by a voice (p >.05), and the ratio of chest compression to ventilation kept 30:2, when the subject made a sound (p <.05). Conclusion : Making voice during CPR was associated with an accurate ratio of 30:2 and the reduction in hands off time.

Purpose: The purpose of this study was to determine the effects of knowledge and attitude on self efficacy of cardiopulmonary resuscitation (CPR) in the fifth and the sixth grade of elementary school students. Methods: The participants were 242 elementary school students from A city. Data were collected from August 26 to August 27, 2013 using a questionnaire. Data analysis was performed by SPSS/WIN 19.0 using ANOVA, t-test, Pearson correlation and stepwise multiple regression. Results: Factors affecting on self efficacy to CPR were attitude (${\beta}=.54$), religion (${\beta}=-.16$), recognition (${\beta}=.15$) and knowledge (${\beta}=.13$). These factors explain 47.0% of the variance in self efficacy. Conclusion: The results of this study show that attitude to CPR has the strongest influence on efficacy. Based on the results of this study, we suggest that customized programs and further research by using 2010 guideline are needed to develop for elementary school students.

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.

Purpose: This study sought to determine how the act of performing cardiopulmonary resuscitation (CPR) affects the rescuer's muscle tone, stiffness, and fatigue in the lumbar region. Methods: The research subjects were 30 healthy men in their twenties in possession of a Basic Life Support (BLS) provider certificate. In this study, the CPR rescuer's muscle tone and stiffness in the upper and lower lumbar regions were measured in the resting position, starting position, and position after 10 min. Their level of fatigue was measured before and after performing CPR. Results: Muscle tone and stiffness in the upper and lower lumbar regions of the research subjects significantly increased throughout the CPR process and lasted up to 10 min after the process (p<.001). The subjects' fatigue also significantly increased post-CPR (p<.001). Conclusion: This study suggests that performing CPR creates muscular and physiological stress, fatigue, and ultimately, lower back pain.

Purpose: The study was done to identify variations in Nurses' CPR knowledge, attitude and performance before and after BLS Education. Method: This study was designed to evaluate the differences in Nurses' CPR knowledge, attitude and performance. For the study we selected 167 nurses working in Daegu K University hospital. The study group was given a test before (pre test) and after (post test) BLS education. The BLS education was given by two BLS instructors certified by the American Heart Association, using a DVD and manikin. Result: The results showed a statistically significant difference the nurse's knowledge, belief, emotion and performance but there was no significant difference in their behavior after BLS education. CPR knowledge and performance was higher among emergency room nurses compared to surgical ward nurses. Conclusion: CPR education has shown to have a positive effect on nurses' attitudes towards CPR. It also improved their related knowledge and performance. Therefore, cardiopulmonary education should be given continuously, and different steps of CPR education programs need to be developed in order to fill the knowledge deficiency gap.

Cardiopulmonary resuscitation (CPR) is an emergency treatment that stimulates blood circulation and breathing when the function of the heart stops or stops breathing. CPR can be divided by basic life support (BLS) and advanced life support (ALS). BLS involves the use of chest compression to force the blood flow to the main organs, rescue breathing to improve the breathing to the respiratory failure patient and the use automated external defibrillator (AED). The categories of advanced life support include advanced cardiovascular life support (ACLS) for adult and pediatric advanced life support (PALS) for children. In the treatment of dental care for children, which is extremely difficult to deal with, and for a variety of reasons, the use of sedation is considered to treat the children who are unlikely to cooperate with dentistry. This is why there is an increasing possibility of an emergency situation involving cardiac arrest. PALS includes the BLS, and it presents a systematic algorithm to treat respiratory failure, shock and cardiogenic cardiac arrest. In order to manage emergency situations in the pediatric dental clinic, respiratory support is most important. Therefore, mastering professional PALS, which includes respiratory care and core cases, particularly upper airway obstruction and respiratory depression caused by a respiratory control problem, would be highly desirable for a physician who treats pediatric dental patients. Regular training and renewal training every two years is necessary to be able to immediately implement professional skills in emergency situations.

Purpose: The object of this study was to compare the educational effect about self-efficacy and the quality of chest compressions of Hands-only CPR and Basic CPR. Methods: It's a nonequivalent control group pre-post repeated quasi-experiment study conducted with entire fifth grade students belong to one school in H city. The study participants are 68 persons, and data were collected from December 2, 2013 to February 7, 2014. Self-efficacy was measured by 10 items, and the quality of chest compressions was measured by 5 variables which are average compression depth(mm), average rate (n/min), average count per minutes (n), abnormal placement (n), compression accuracy (%). Results: Self-efficacy of the experimental group and control group showed no significant difference but showed significant difference over time and was the highest at posttest 1 (immediately after education), the lowest at pretest (before education), middle at posttest 2 (8weeks after education) (p<.001). Experimental group was significantly higher than control group in average rate per minute. At posttest 1, experimental group was $130.0{\pm}9.38$ times, control group was $95.1{\pm}11.82$ times. At posttest2, experimental group was $124.0{\pm}14.89$ times, control group was $90.8{\pm}14.89$ times.(p<.001). Average rate (n/min) was significantly declined at control group in the quality of chest compressions over time (t=-2.400, p=.022). Average count per minute and compression accuracy were declined significantly so it were not maintained to posttest2. Conclusion: We need continuous CPR education because self-efficacy of CPR getting lower significantly over time. Hands-only CPR can't be seen as a way to increase the CPR ability of elementary school students having difficulty to perform artificial breathing. And, because the effect of education is not maintained 8wks after training, the technique centered repeated training is needed and a method which can increase compression accuracy is also needed.
