Background/Objectives: It is convenient to apply C-E technique during ventilation using bag-valve mask in the moving ambulance. Purpose of the study is to investigate the effective ventilation volume and airway pressure.
Methods/Statistical Analysis: The National Fire Service Academy conducted Virtual Reality (“VR”) based ambulance simulations from April 17, 2018 to April 28, 2018. The mean and standard deviations of mean ventilation and airway pressure were analyzed using descriptive statistics and ANOVA and SPSS software 12.0 (SPSS Ins., Chicago, IL, USA) program.
Findings: When VR-based intubation was performed, the ventilation volumes were 375 ml (±30.71), 225 ml (±8.48), 324 ml (±6.56), 244 ml (±7.79), and 427 ml (±10.42) when using bag-valve mask, laryngeal mask, laryngeal tube, I-gel, and intubation, respectively. Airway pressure was 17.48 cm H2O (±0.28) from endotracheal intubation, 14.79 cm H2O (±1.51) from bag-valve mask, 13.49 cm H2O (±0.78) from laryngeal tube, 8.66 cm H2O (±0.80) from I-gel, 6.73 cm H2O (±0.53) from laryngeal mask showed airway pressure.
Improvements/Applications: The present study has significance in that basic data for the method of using a professional airway are provided by adequate ventilation for each professional airway in transit.

Background/Objectives: As the field activity of the fire fighter is increased increasing the exposure to the traumatic event, the development of effective program to reduce the job stress is needed.
Methods/Statistical Analysis: The present study investigated levels of emotional intelligence, self-efficacy, and job stress by personal characteristics, working environment of ambulance workers, and grasped their correlations. A survey of ambulance workers in service at fire stations in the northern Gyeonggi province was conducted from Feb. 22 to Mar. 31, 2019 and 160 questionnaires were analyzed. Collected data were subjected to frequency analysis, t-test, and ANOVA using SPSS software 12.0 program.
Findings: Emotional intelligence showed a score of 63 out of 80 points. Emotional intelligence of females was higher than that of males. That of workers not younger than 35 years was higher than that of workers younger than 30 years. That of fire engineers or fire lieutenants was shown to be higher than that of firefighters. Job stress of females was higher than that of males. That of EMT level 2 qualification holders or workers who took the training course was shown to be higher than that of EMT level 1 qualification holders. That when less than three workers were mobilized was shown to be higher than that when three workers and more were mobilized. Self-efficacy showed a positive correlation with emotional intelligence but a negative correlation with job stress. Emotional intelligence showed a negative correlation with job stress. The higher the emotional intelligence, the higher the self-efficacy. The higher the emotional intelligence and self-efficacy, the lower the job stress.
Improvements/Applications: To reduce the job stress, the health should be improved and the field response capability should be enhanced by establishing the strategy to enhance the emotional intelligence.

Background/Objective: This study aimed to verify the quality and the appropriateness of pediatric CPR chest compressions according to 2015 Korean Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.
Method/Statistical Analysis: The participants of this study were 64 EMT and nursing students who were quailified as BLS providers. Four sets of 5 CPR cycles were performed with one hand and two hands at the ratio of chest compression (30 times) to respiration (2 times), and fatigue was confirmed by NRS(numeral rating scale). Collected data were analyzed using frequency, descriptive statistics, paired t-test, and repeated measure ANOVA by SPSS 22.0.
Findings: While the total number of chest compressions (629.6 times vs. 618.3 times, p=.016) and hands-off time (6.6 sec vs. 6.9 sec, p=.006) were effective for one-handed chest compression, average pressure depth (42.2mm vs. 43.8mm, p<.001), sufficient chest compression depth rate (83.0% vs. 89.1%, p=.038) and fatigue (7.0 points vs. 6.2 points, p=.040) were more effective in two-handed chest compressions. In addition, there were significant differences in the average chest compression depth over time(p=.003) and the total elapsed time (p=.332), but no significant difference in inappropriate chest compression.
Improvements/Applications: Performing pediatric CPR according to the 2015 Guidelines for Pediatric Cardiopulmonary resuscitation is acceptable, but it is necessary to consider two-hand chest compression more than one hand compression.
