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).

This study was conducted to evaluate the influence of educational experience and attitude toward performance confidence of cardiopulmonary resuscitation amongcare helpers. This study was conducted using a descriptive survey design. Participants were 140 care helpers in C-province. Data were collected from February to April, 2017 using self-report questionnaires andthe collected data were analyzed using the SPSS WIN 20.0 program. Differences amongstudy variables by participants' characteristics were analyzed by a t-test, ANOVA, and Scheffe' test. Correlations between attitudes and confidence of CPR performance by Pearson's correlation coefficients. Factors influencing confidence in CPR were analyzed by Multiple regression. There were significant positive correlations between attitude and confidence in CPR(r=0.41, p<0.001). The result showed that the more than fourhours of education(${\beta}=0.28$) and a positive attitude toward CPR increased CPR performance confidence. Based on the present findings, CPR education should be included continuously in the workplace and developed to appropriately cope with cardiac arrest emergency situations in care facilitiesfor elderly people. Therefore, customized CPR education programs should be developed care helpers and included in job training and refresher education courses for care helpers.

Background: The use of extracorporeal life support (ECLS) in the setting of cardiopulmonary resuscitation (CPR) has shown improved outcomes compared with conventional CPR. The aim of this study was to determine factors predictive of survival in extracorporeal CPR (E-CPR). Methods: Consecutive 85 adult patients (median age, 59 years; range, 18 to 85 years; 56 males) who underwent E-CPR from May 2005 to December 2012 were evaluated. Results: Causes of arrest were cardiogenic in 62 patients (72.9%), septic in 18 patients (21.2%), and hypovolemic in 3 patients (3.5%), while the etiology was not specified in 2 patients (2.4%). The survival rate in patients with septic etiology was significantly poorer compared with those with another etiology (0% vs. 24.6%, p=0.008). Septic etiology (hazard ratio [HR], 2.84; 95% confidence interval [CI], 1.49 to 5.44; p=0.002) and the interval between arrest and ECLS initiation (HR, 1.05 by 10 minutes increment; 95% CI, 1.02 to 1.09; p=0.005) were independent risk factors for mortality. When the predictive value of the E-CPR timing for in-hospital mortality was assessed using the receiver operating characteristic curve method, the greatest accuracy was obtained at a cutoff of 60.5 minutes (area under the curve, 0.67; 95% CI, 0.54 to 0.80; p=0.032) with 47.8% sensitivity and 88.9% specificity. The survival rate was significantly different according to the cutoff of 60.5 minutes (p=0.001). Conclusion: These results indicate that efforts should be made to minimize the time between arrest and ECLS application, optimally within 60 minutes. In addition, E-CPR in patients with septic etiology showed grave outcomes, suggesting it to be of questionable benefit in these patients.

Objectives: The purpose of this study is to compare educational effects between traditional classroom instruction and video self-instruction (VSI) for cardiopulmonary resuscitation (CPR) in boy's high school students. Methods: This study was carried out targeting totally 96 boy students(47 people for experimental group, 49 people for control group) in the second grade of high school where is located in G city of G province from July 9-10, 2009. The experimental group and control group were arbitrarily selected two classes in the second grade. One class was assigned to the experimental group. another class was assigned to the control group. The experimental group was educated with VSI for CPR. The control group was educated with traditional classroom instructions for CPR. The analysis was performed with SPSS WIN (version 12.0) program using frequency chi-square($x^2$) test, independent samples t-test, and paired t-test. Results: After instructions, the knowledge, attitude, self-confidence, and skill performance accuracy scores on CPR increased statistically in both group. The increases of self-confidence ($2.40{\pm}0.73$) and skill performance accuracy score ($2.67{\pm}0.29$) in the experiment group were significantly higher than those ($2.01{\pm}0.96$ and $2.54{\pm}0.31$) in the control group, respectively. Conclusion: This study suggested that VSI was more effective than traditional classroom education for self-confidence and skill-performance accuracy in CPR. To confirm it, more studies are warranted.

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.

This research, by analyzing the current first aid education status in K district, Seoul and comparing first aid education systems in other developed countries, introduces the need of first aid/Cardio Pulmonary Resuscitation(CPR) education with Automated External Defibrillator(AED) usage to high school students, who are on the verge of becoming adults. The thorough research shows that schoolsshould be appointed as mandatory facilities for AEDs by laws and execute first aid education to their students. Only through organized and consistent first aid education would the students develop into true volunteers who not only have altruistic minds, but the ability to fluently adapt to medical emergency and properly use AED. In addition, the research also outlines various laws that could be legislated such as having to master the basic degrees of first aid education before getting driver's license and graduating high school so that more people become aware of first aid.

Cardiopulmonary resuscitation(CPR) is performed by artificial ventilation and thoracic compression for the patient under emergent situation to maintain at least the minimum level of respiration and blood circulation for life survival. Quality of the pre-hospital CPR not only significantly affects the patient's survival rate but also minimizes side effects caused by CPR. Good quality CPR requires monitoring respiration, however, traditional respiratory air flow transducers cannot be used because the transducer elements are located on the flow axis. The present study developed a new technique with no physical object on the flow stream but enabling the air flow measurement and easily incorporated with the CPR devices. A turbulence chamber was formed in the middle of the respiratory tube by locally enlarging the cross-sectional area where the flow related turbulence was generated inducing energy loss which was in turn converted into pressure difference. The turbulence chamber was simply an empty enlarged air space, thus no physical object was placed on the flow stream, but still the flow rate could be evaluated. Both inspiratory and expiratory flows were obtained with symmetric measurement characteristics. Quadratic curve fitting provided excellent calibration formula with a correlation coefficient>0.999 (P<0.0001) and the mean relative error<1 %. The present results can be usefully applied to accurately monitor the air flow rate during CPR.

Purpose: The purpose of this study was to analyze the cardiopulmonary resuscitation skills and teamwork of nurses in simulated cardiac arrests in the hospital. Methods: A descriptive study was conducted with 35 teams of 3 to 4 registered nurses each in a university hospital located in Seoul. A mannequin simulator was used to enact simulated cardiac arrest. Assessment included critical actions, time elapsed to initiation of critical actions, quality of cardiac compression, and teamwork which comprised leadership behavior and communication among team members. Results: Among the 35 teams, 54% recognized apnea, 43% determined pulselessness. Eighty percent of the teams compressed at an average elapsed time of $108{\pm}75$ seconds with 35%, 36%, and 67% mean rates of correct compression depth, rate, and placement, respectively. Thirty-seven percent of the teams defibrillated at $224{\pm}67$ seconds. Leadership behavior and communication among team members were absent in 63% and 69% of the teams, respectively. Conclusion: The skills of the nurses in this study cannot be considered adequate in terms of appropriate and timely actions required for resuscitation. Future resuscitation education should focus on improving the quality of cardiopulmonary resuscitation including team performance targeting the first responders of cardiac arrest.
