The aim of this study was to report the out-of-hospital resuscitation of cardiac arrest along with literature consideration. CPR is technology of resuscitating patient by maintaining oxygen supply to organ, by preventing progression from clinical death to biological death, and by recovering heart beat and circulation, through circulatory support of mechanical ventilation. It is not what every patient with cardiac standstill is revived even if being implemented CPR. Patient's survival rate is decided by how quickly and correctly CPR was executed. A patient, who wasn't witnessed the cardiac arrest on the field, was performed 5-cycle CPR for 2 minutes on the field before being transferred to hospital, and was allowed to be used AED. A person, who was observed, is recommended to be used AED immediately, and then is said to be needed ACLS (advanced cardiac life support). In the Out-of-Hospital stage, it is rare in a case that 119 Emergency Medical Service System transfers by being ROSC and in a case of executing ACLS. Cardiac arrest was witnessed on the field, but CPR wasn't executed. First-aid staff executed CPR after arriving, and led to ROSC on the field with ACLS, there by having experienced 1 case of a patient's surviving to leave hospital by being ROSC on the field.

Most schools and educational institutions, as well as most companies, show willingness to teach CPR. However, as an essential element for the health care workers, this study aims to analyze the appropriate timing of education and improvements to the education, focusing on those who have trained for CPR. The survey was conducted for only those who applied for CPR education regardless of their profession in medical institutions. There were 105 males and 93 females by gender, and an average of 198 females were 33.5 years. The difference in CPR education depending on individual characteristics showed a high demand that all research subjects' gender, age and marital status should be improved to a practical education. During the education period, the efficiency of CPR was high. It is expected that the education of CPR will be used for the improvement of the training cycle and the training content since it is the enhancement of the performance capabilities that require practical application.

Purpose: The first responder's role during a cardiac arrest scene is to initiate CPR. The AHA has recognized and included the first responder's role for improving the survival rate of cardiac arrest patients. Health personnel working in nursing, emergency care, dental hygiene, radiology, and ocular optics frequently confront sudden cardiac arrest while working. This study was to identify the relationship between the educational experience and recognition with the level of knowledge about CPR for college students. Method: Five hundred forty college students enrolled in the department of nursing science, radiological technology, ocular optics, emergency medical technician, or dental hygiene in Daejeon city were surveyed. The tool used was CPR knowledge developed by the authors based on a literature review including 2005 AHA's CPR guideline. Result: The higher educational experience of CPR was, the higher the level of knowledge. The knowledge of the students in nursing or emergency medical technician was higher than students in dental hygiene, radiology, and ocular optics. Conclusion: CPR class should be included in the curriculum for college students in order to improve their accuracy as a first responder to cardiac arresting patients.

Purpose : The purpose of the present study is to analyze the accuracy and fatigue felt by lay persons receiving CPR training when they perform hands only CPR (HOCPR) and traditional CPR (TCPR). The performance of CPR data will provide the criteria of dispatcher guidelines for the general public. Methods : For 2 minutes duration, HOCPR was conducted by 51 subjects and TCPR was conducted by 48 subjects. The accuracy measurement of chest compressions was based on the 2010 AHA guideline; the subjective fatigue level in before and after experiment was measured by a self-administered questionnaire. Results : There were no significant differences between the average depth, chest compression depth and chest compression location in terms of chest compression accuracy. However, there were significant differences between the two experimental groups in the accuracies for average speed and chest compression speed. The subjective fatigue level showed no significant difference. Conclusion : The experimental group performing HOCPR showed more accurate compression speed and lower fatigue level. These results suggested that HOCPR would be more effective in training the lay persons in accordance with the voice-instructed CPR.

This study analyzed the physical changes in 119 paramedics transporting equipment at the emergency site and performing post-cardiopulmonary resuscitation through experiments. First, the average heart rate increased by about 25 times comparing CPR was performed without physical load and with personal protective equipment after moving equipment. In the third quartile, it increased to about 27 times. Second, when CPR was performed without physical load, and CPR was performed after moving the equipment with personal protective equipment, both the body temperature was raised and the rising body temperature was measured within normal body temperature. Third, the change in respiration rate increased by 7 times on average comparing CPR was performed without physical load and CPR was performed after moving the equipment while wearing personal protective equipment. In the third quartile, it increased to about 11 times. Finally, the change in blood pressure increased by 26.6 mmHg on average comparing CPR was performed without physical load and with wearing personal protective equipment after moving the equipment, and increased by 31.2 mmHg on average in the third quartile.

This study is focused on middle school students who are composed of a factor in medical emergency system. In the case of cardiac failure, it is to make its basic data and develop its education program of CPR(cardiopulmonary resuscitation) which can increase the patient's survival rate before his hospitalization. The findings of this study is as follows. The subject of study is composed of 117 persons who are 54 boy-students(46.2%) and 63 girl-students(53.8%) in sex and 72 first-grade students(61.5%) and 45 second-grade students (38.5%) in a school year. In the accuracy degree, the practice of artificial respiration is $42.28{\pm}34.42%$ in case of basic CPR(cardiopulmonary resuscitation). The accuracy degree of the thorax pressure is $82.17{\pm}15.40%.$ In the accuracy degree, the practice of artificial respiration is $92.16{\pm}25.68%$ in boy-students and $20.38{\pm}24.16%$ in girl-students, the second-grade students is $58.40{\pm}33.29%$, which is higher than the first-grade students' $32.21{\pm}31.14%$. In the accuracy degree, the thorax pressure is $92.16{\pm}3.91%$ in boy-studetns and $73.61{\pm}16.41%$ in girl-students. In the accuracy degree of the thorax pressure, the second-grade students are $82.60{\pm}16.54%$ and the first-grade students $81.91{\pm}3.91$, which doesn't show any significant difference in school year. The satisfaction degree after theory & practice education is $2.12{\pm}.85$. In the satisfaction degree of its basic CPR, girl-students are $2.14{\pm}.83$ and boy-students are 2.11. In the satisfaction degree of its basic CPR, the second-grade students are $2.40{\pm}.61$ and the first-grade students are $1.95{\pm}.94$. This study is to lead to some suggestions. First, it is necessary to develop the education program and educate its knowledge & technology in proportion to student's characteristics of sex and school year. Second, education authorities should develop a subject of the accident prevention and first-aid treatment in its curriculum and provide the practical education of CPR for adults, adolescents and children. Third, it is necessary to study the education program as well as the education evaluation of CPR further on.

This study was carried out as a descriptive correlation study to identify the knowledge and performance of CPR of nursing students who have experience in CPR education and to explore the relationship between them. Participants in this study were 204 nursing college students who were enrolled in the 4th year of nursing at two universities located in G Metropolitan City from October 18 to October 30, 2018. For the collected data, IBM SPSS Win 21.0 version Program was used. The correlation between the subject's CPR knowledge and performance was evaluated using the Pearson Correlation Coefficient. There was a positive correlation between CPR knowledge and CPR performance (r=.22, p=.01), and it was found that the higher the CPR knowledge, the higher the CPR performance. Since this study is convenient extraction of nursing students from two universities in G Metropolitan City, there may be limitations in generalizing the results of this study. It is a self-reported indirect measurement rather than a direct measurement that measures by observing, reflecting the subject's subjectivity, and there is a concern that the effect of education may not be measured objectively. Therefore, further research using a direct measurement tool of CPR performance is needed.

Purpose: The purpose of this study is to help care workers to do their best as first respondents by analysing their recognition, knowledge, and self-efficacy on basic CPR (cardiopulmonary resuscitation) that is directly connected to the lives of patients and thus their education and methods can be improved for their positive basic lifesaving work. Method: For this purpose 360 structured questionnaires were used to the subjects in the eastern area of Jeonnam province from June 20 to July 4, 2011. Of these questionnaires 217 were used excluding 113 incomplete, 27 error, and 3 male ones. The collected data were analysed by the real number, the percentage, the average, the standard deviation, t-test, ANOVA, and Tukey with SPSS WIN 18.0. Results: 1. In the view of subjects, those aged over 51 accounted for 96(44.2%) as the majority, high school graduates, 95(43.8%), worked for 1 or more than 1 year-less than 2 years, 66(30.4%), experienced to see persons collapsed losing their consciousness, 46(21.2%), took the education, 184(85.7%), had 1 session of education, 80(43%), got the last education for 2 or more than 2 years 68(37%), and practiced through mannequin for the education aids, 86(46.7%). 2. There was significant difference in the view of recognition with the length of work (p=.010) and experienced to see persons collapsed losing their consciousness (p=.020), in the view of knowledge with academic background (p=.040) and the length of work, and in the view of self-efficacy with academic background (p=.002), the length of work (p=.010) and experienced to see persons collapsed losing their consciousness (p=.000). 3. There was significant difference in the session of education (p=.000), last education (p=.025) and education aids for basic CPR. Self-efficacy had significant difference according to the session of education for basic CPR (p=.001) and the time of education (p=.000). 4. There was correlation between recognition and self-efficacy (r=.41). The higher the recognition is, the better the self-efficacy improves. However the correlation between knowledge and self-efficacy was so low that the former did not have influence on self-efficacy. Conclusions: It needs to offer education to the lifesaving workers based on their experiences. If there is education more than 2 sessions in a year with mannequin and the simulation providing sufficient hours, care workers' recognition would be increased resulting in higher self-efficacy and thus they could keep the role of active lifesaving worker at the first practical site.

Application of the left lateral tilt position has been recommended during cardiopulmonary resuscitation (CPR) of pregnant patients. However, the left lateral tilt could displace the left ventricle (LV) besides the gravid uterus and may compromise the cardiac pump mechanism of CPR. Thus, we investigated the effect of left lateral tilt on the spatial relationship between the anterior-posterior axis (AP axis), which represents the direction of sternal displacement during CPR, and the LV. We retrospectively reviewed the medical records and multidetector computed tomography (MDCT) scans of 90 patients who underwent virtual gastroscopy using MDCT. Virtual gastroscopy was performed with the patient both in the left lateral tilt position and in the supine position. On an axial image showing the maximal area of the LV, the angle between the AP axis and the LV axis ($Angle_{AP-LV}$), the shortest distance between the AP axis and the mid-point of LV cavity ($D_{AP-MidLV}$) and the shortest distance between the AP axis and the LV apex ($D_{AP-Apex}$) were measured. In the supine scans, the LV was situated on the left side of the AP axis in 87 patients (96.7%). On the left lateral tilt scans, the mean tilt angle was $43.4{\pm}11.0^{\circ}$. $D_{AP-MidLV}$ and $D_{AP-Apex}$ were significantly longer in the left lateral tilt position (p<0.001), but $Angle_{AP-LV}$ was comparable between the positions. This study indicates that the left lateral tilt position may compromise the cardiac pump mechanism of chest compression in pregnant cardiac arrest patients.

Purpose: The purpose of this study was to determine the effects of CPR training for nursing students on their knowledge, attitude and perceived competence. Methods: This study was a nonequivalent control group pretest-posttest design. The participants were 54 nursing students who were conveniently assigned to an experimental or control group. The data was collected from October 22 to November 20, 2007 and analyzed by using $x^2$-test and t-test. Results: The first hypothesis,“Posttest CPR knowledge scores in the experimental group will be higher than those in the control group”was supported(t=4.257, p=.000). The second hypothesis,“Posttest CPR attitude scores in the experimental group will be higher than those in the control group” was supported(t=3.664, p=.001). The third hypothesis,“Posttest CPR perceived competence scores in the experimental group will be higher than those in the control group”was supported(t=6.49, p=.000). Conclusion: The CPR training was the effective strategic method to increase the levels of knowledge, attitude, and perceived competence for nursing students.
