The purpose of this research was to evaluate retention of cognitive knowledge, psychomotor skills and self-confidence on CPR 3 months after CPR training program. The sample consisted of 39 nursing students. We provided one rescuer CPR training program for nursing college students on the basis of AHA. The questionnaires for knowledge of CPR were developed 50 items based on AHA guidelines. Self-confidence were checked by 11 items questionnaires. The accuracy of CPR skills were checked by Skillreporter CPR training manikin and by researcher's evaluation based on CPR skill checklist. The results were as follows ; 1. The majority of participants didn't have any previously experiences of CPR training (76.9%). Only 15.1% previously took the CPR training with CPR practice. 2. In terms of self-confidence of CPR. The score were increased for 2 days (p>.001) but retention of self confidence was significantly statistical decreased in 3 months after training (p<.001). 3. There was a statistically significant decrement in mean of knowledge of CPR between 2 days and 3 months after CPR training (p<.001). 4. There was a statistically significant decrement in cognitive knowledge of CPR based on CPR skills checklist(p<.001). 5. Retention scores of psychomotor skills of CPR 3 months after training were 42.10% in numbers of adequate ventilation, 52.81% in numbers of adequate chest compression (p<.001) respectively. 6. Retention of passing rate on chest compressions of CPR 3 months after training was 27% (p<.001), on ventilation was 2.63% (p>.001). The error items with statistically significant differences 3 months after CPR training were too little ventilation (74.36%) and too little chest compressions (92.31%). The results of the study suggest that we need further evaluation of course components which could improve retention of CPR for all trainees.
Purpose: Cardiopulmonary resuscitation (CPR) prevents tissue necrosis of the brain and cardiac muscle in the cardiac arrest patient and requires exact skills in order to increase survival rate. Through comparison of the training effects of feedback manikin and non-feedback manikin, this study present the effective CPR device to CPR instructors. Method: This CPR course for 80 students by using Resusci Anne $SkillReporter^{TM}$ (RASR; Laerdal Medical, Stavanger, Norway) and Actar 911 $Squadron^{TM}$ (A911; Vital Signs, New Jersey, USA) held on December 22, 2009. Thirty seven students and two assistants were placed in one laboratory, there were five RASR manikins which provide the LED performance indicator, not the metronome. Forty two students and two assistants were placed in the other laboratory, there were 20 A911 manikins which don't provide any feedback indicator. Chest compression scores and ventilation compression scores obtaining from two groups were analysed statistically by using independent t-test. Results: Chest compression scores, average depth (mm) was 37.5 in RASR and 41.80 A911 (p=.004), too depth (#) was 2.8 in RASR and 19.4 A911 (p=.005), average number per min (#/min) was 64.4 in RASR and 68.2 A911 (p=.038), wrong hand position (#/min) was 10.9 in RASR and 30.8 A911 (p=.040). Four items that showed better scores in group RASR had statistically significant difference. Ventilation compression scores, percent correct (%) was 40.6 in RASR and 20.6 A911 (p<.001), number correct (#) was 4.7 in RASR and 2.1 A911 (p=.002), too fast (#) was 0.9 in RASR and 2.9 A911 (p=.003), average volume (ml) was 536.5 in RASR and 707.1 A911 (p=.011). Also, three items that showed better scores in group RASR had statistically significant difference. Conclusions: Regarding the positive effect of CPR training feedback, comparison between the real-time visual feedback manikin (RASR) and the non-feedback manikin (A911) showed that RASR had better results than A911 in chest compression except average number per min (it means that we need harder chest manikin) and ventilation. Verification of the training effect in the real world such as CPR outcomes is also necessary. A proper application of manikin in training circumstances and research on retention of CPR skills will be needed.

Purpose: The purpose of this study was to evaluate the learning experience, knowledge, and performance of cardiopulmonary resuscitation (CPR) in newly graduated nurses, and to identify differences related to learning experience. Methods: The participants were 114 new nurses in the hospital. They were asked to complete a questionnaire, which included CPR learning experience. They were evaluated by a written test and a skill test using a manikin and check list. Results: All participants attended CPR lectures and underwent practice while in university. Only 12.28% of participants were taught by a certified Basic Life Support (BLS) instructor. The mean scores of the written and skill tests were $79.82{\pm}12.69$ and $64.41{\pm}11.71$, respectively. The nurses lacked CPR knowledge related to checking breathing, the frequency of 30 chest compressions, compression rate, and automated external defibrillator use. They also lacked skill in performing CPR related to checking breathing and pulse and giving 2 breaths. CPR performance differed according to learning time (p=.047) and BLS educator (p=.029). Conclusion: The findings of this study reveal that CPR performance by newly graduated nurses is poor and suggest that CPR education by trained instructors, practice-based education, and reeducation programs must be provided to newly graduated nurses in the hospital.

The purpose of this study is to increase efficiency and accuracy in operation of CPR(Cardiopulmonary Resuscitation) through comparing accuracy in CPR between group with verbal order and group with non-verbal order given carrying out CPR. This study performed convenience sampling targeting 62 students(31 people for group with non-verbal order, 31 people for group with verbal order) at university where is located in G Province. Survey period was carried out from October 7, 2010 to October 21. Analytical method was made by using SPSS WIN(Version 12.0). As a result of research, the group with non-verbal order was indicated to be higher in accuracy of CPR on artificial respiration and chest compression in several spheres than the group with verbal order. Based on this, the non-verbal order method needs to try to be applied to performing education and skills of CPR in the future. And, even a continuous research is needed on effectiveness between verbal order method and non-verbal order method in an emergency situation.
The purpose of this study is to find out its effect on changes in the joint angle and the success rate of cardiopulmonary resuscitation by conducting cardiopulmonary resuscitation (CPR) when wearing and not wearing PPE (personal protective equipment) targeting 20 paramedics with more than 5 years of experience. The subjects carried out CPR in 30:2 for 4 minutes and collected images were digitized by Kwon3D XP Software Package(Version 4.0) and then data were obtained. Data, which were collected by analyzing the motion when starting in one cycle, when pressing to the maximum, in the final position (relaxed), were analyzed by using SPSS 18.0. In conclusion, during CPR, the angle of the both shoulder joints was not significant (p>.05) and the angle of the right elbow joint was reduced in all positions and was statistically significant (p<.05) and the angle of the left was significantly reduced in the maximum pressure posture and the final position (p>.05). In the case of the trunk, the angle increased statistically significantly at all stages (p<.01, p<.001). Also, during CPR, the average compression rate was significantly reduced after wearing PPE (p<.05) and average hand escape time by cycle increased statistically significantly (p<.05) but chest compression execution rate at the correct depth did not show any significant difference between the two groups (p>05).

Objectives: This study aims to perform comparative analysis of educational effects between video self-instruction (VSI) and basic cardiopulmonary resuscitation among college students in some areas. Methods: This study was conducted with 57 college students (28 for control group and 29 for experimental group) in U Metropolitan City from September 27 to October 5, 2007, and SPSS 14.0 Version was used for analysis. Results: As for differences in attitudes before and after cardiopulmonary resuscitation training, the experimental group (1.48) was higher than the control group (.91), which was significant (p<.001). The experimental group (9.56) also showed higher knowledge score than the control group (7.79) with significant differences (p<.05). The former (3.93) also showed higher concrete self-efficacy than the latter (2.17). with significant differences (p<.05). The experimental group (43.24) showed higher practical performance ability than the control group (34.48), with no significant difference. The former (30.93) also showed higher accuracy in chest compression skill than the control group (20.25). with no significant difference.
Purpose: The I-gel device is Korea's most frequently used airway management method during pre-hospital cardiopulmonary resuscitation (CPR). This study aimed to compare changes in ventilation volume according to the fixation method with a simulated manikin. Methods: We placed I-gel into an advanced life support simulator and compared tape and band fixation conditions. CPR was performed according to the 2020 Korean CPR guidelines, using a mechanical chest compression device and an adult bag. The positional shift of I-gel and the ventilation volume of the simulated manikin were measured after performing CPR for 20 minutes. Five trials were carried out in each setting. Statistical analysis was carried out with SPSS 27.0. P < .05 was considered significant. Results: Positional shift after 20 minutes of CPR was as follows: tape fixation, 7.2 ± 0.2 mm; band fixation, no change, indicating a significant difference between the two groups (p=.003). The mean ventilation volume was tape fixation, 482.63 ± 30.84 mL; band fixation, 544.96 ± 22.98 mL, showing a significant difference (p=.002). Conclusion: When using the I-gel during pre-hospital CPR, using a band-type fixing device with elasticity rather than fixing the tape provides stable and appropriate ventilation by maintaining the fixed position.

Offshore working environments such as ships, offshore oil and gas plants, and offshore wind turbines are isolated and directly exposed to rough seas, which pose high risks of safety accidents. Therefore, all workers in offshore plants should be able to cope with emergency situations and must be qualified according to relevant laws and regulations such as the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW Convention) and Offshore Petroleum Industry Training Organization (OPITO) standards. In particular, marine workers should be able to perform cardiopulmonary resuscitation (CPR) in isolated locations or enclosed and confined spaces such as those in life-boats, life-rafts, rescue-boats, etc. Because the floor material is made of rubber, it may be difficult to perform chest compressions in life-rafts used to escape from emergency situations in ships or offshore plants. Chest compressions performed on life-rafts may reduce the accuracy of CPR and increase fatigue for those providing aid. To measure the accuracy and fatigue of those performing CPR in life-rafts, 15 experimenters with more than five years of experience as first aid instructors were exposed to different CPR environments in a marine safety training center equipped with an artificial wave generator. The results showed that the accuracy of CPR in the classroom was 99.6 %, but that in various life-raft environments was only 84 %. T-verification of the two sites confirmed the reduced accuracy of CPR performed on life-rafts. CPR on life-rafts should be performed in groups of two and with the use of automated chest compression devices.

The purpose of this study was the accuracy of cardiac compression, fatigue, and physiological changes of the rescuer for different mask type in cardiopulmonary resuscitation(CPR). Data collection was from 9 to 12 May 2022, the participants were a total of 24 paramedic students with a BLS provider at D University. The students participated in an experiment in which 12 students each wore a surgical mask (Dental mask) and a fine particle 94% blocking mask (KF94 mask) and performed CPR for 2 minutes over a total of 7 times. As a result of the study, in the analysis of the quality of the rescuer's chest compression according to the type of mask, there was a significant difference in the compression speed (F=24.91, p<.001) and bad compression hand position (F=14.54, p=.024) in the group wearing the KF94, Fatigue showed significant differences in both the Dental mask group (F=51.16, p<.001) and the KF94 mask group (F=63.49, p<.001). Among the physiological changes, heart rate showed a significant difference between the Dental mask group (F=34.79, p<.001) and the KF94 mask group (F=35.55, p<.001), and the respiratory rate showed a significant difference between the Dental mask group (F=25.02, p=.001) and the KF94 mask group(F=23.02, p=.002). Therefore, in order to improve the quality of efficient chest compression and reduce the fatigue and physiological changes of rescuers, it will be necessary for rescuers to wear suitable personal protective equipment.
