Purpose: The aim of this study was to evaluate the usefulness of video communication with medical staff located at a remote location, through a communication application connected to a long term evolution (LTE) mobile communication network in a moving ambulance. Methods: In this study, we recruited patients who were transferred by mobile intensive care unit ambulance from one hospital to another. In the moving ambulance, the information of the patient was transferred to a physician using the application in real time. Recorded video files were evaluated by emergency physicians with experience in video direct medical control. Results: A total of 18 patients were evaluated, and the average score was 5.9 out of a possible 9. It was expected that applying the use of the technology to actual clinical sites would enable the sites to provide assistance. Conclusion: In this study, we confirmed the possibility of benefiting from the clinical field when using the video-audio communication application which is connected to the remote location in real time through the current LTE mobile communication network in the ambulance.

The purpose of this study is to perform the effectively advanced airway management in an emergency patient with cardiac arrest and trauma by comparing the appearance of influence in a change of visual-field height upon endotracheal intubation according to a change in position with intubation of paramedics in a moving ambulance and by analyzing the appearance of the influence in a patient's change in position with intubation upon speed in endotracheal intubation. Research subjects were randomly extracted 60(30 people for control group, 30 people for experimental group) people as the paramedics who are working at 13 fire stations in C Province. Data analysis was carried out ${\chi}^2$-test, independent t-test, paired t-test by using SPSS WIN 14.0 Version. As a result of research, to improve speed of the advanced airway management, it is considered to be likely effective in a patient's sniffing position and in the endotracheal intubation in the upper space of the main stretcher. The self-confidence in intubation after experiment increased significantly. Thus, the continuous education(training) on the intubation position and method within ambulance is considered to be likely needed for improving efficiency of the advanced airway management.

Purpose: The purpose of the study was to investigate the causes of non-transport in 119 ambulance services and to describe the difference in response time according to the reason for non-transport. Methods: This study analyzed 42,415 non-transport cases out of 123,158 cases using prehospital care reports in a metropolitan city. The Kruskal-Wallis test and the Wilcoxon-Mann-Whitney test were used to 6,857 cases for which time was recorded. Results: Non-transportation in 20${\bigcirc}{\bigcirc}$ comprised 33.1% of all ambulance services. The reason for non-transport were other reasons (25.5%), cancellation (23.8%), and moving to other vehicles (21.7%). There were differences in ambulance service times according to the reasons for non-transport. The activation interval was the longest (2.68 minutes) in the absence of the patient, and the response interval was the shortest (4.96 minutes) among the cancelled case. The total interval was the shortest time (21.97 minutes) in the cancellation cases and the longest time among the death cases (32.23 minutes). Conclusion: It is important to suggest the direction of development of emergency services by identifying the reasons for non-transport by ambulance services and describing the response time according to the reason for non-transport.

Objective : This study compares Video laryngoscope and Direct laryngoscope in tracheal Intubation on rapidity and accuracy by paramedic and aims to improve efficiency of airway management and survival rate in pre-hospital treatment for the patients with severe trauma, cardiac arrest or dyspnea caused by acute diseases. Methods : 60 paramedics were recruited from 13 fire stations located in C province. With the consent of the paramedics, likelihood ratio test was carried out and they were divided into two different groups; DL group (30) and GVL group (30). Regarding intubation conditions, difficult airway grade I, grade II and grade III as well as sniffing position and neutral position were examined. This study also compared between ambulance in motion and in stand still. Frequency, average and standard deviation were analyzed with statistics program, SPSS WIN 17.0 and repeated measure design was introduced to examine inter-relations between position, grade and groups. Results : Intubation was performed more rapidly in neutral position and GVL than in sniffing position and DL(F = 15.260, p = .000). Rapidity value was better with grade I and grade II than grade III and better with GVL than DL(F = 32.629, p = .000). Accuracy value was higher with neutral position and GVL than sniffing position and DL(F = 5.008, p = .011). grade III was less accurate than grade I, grade II and GVL was more accurate than DL(F = 10.966, p = .000). Ambulance motion status did not show any statistically significant differences in accuracy and rapidity. Conclusion : Given this study results, neutral position is better for the patient with severe trauma. For a better survival, GVL intubation can be considered since GVL can enhance accuracy as well as rapidity regarding difficult airway. Since there is no significant differences in ambulance motion factors, intubation can be recommended even in moving ambulance for shortening traveling time to a hospital.

The purpose of this study was to analyze the measurements of blood pressure and time using manual and automatic blood pressure monitors in various road conditions to verify reliable blood pressure monitor in a moving ambulance. First, the manual blood pressure monitor palpation on unpaved roads showed a systolic pressure deviation of 5 mmHg. However, the automatic blood pressure monitor showed two measurement failures, one reading failure, and the measured systolic pressure deviation was 35 mmHg. The measurement time was 102 seconds faster on average than the automatic blood pressure monitor. Second, the palpation of the manual blood pressure monitor while going over speed bumps remained constant at 130 mmHg. However, the automatic blood pressure monitor had a systolic pressure deviation of 52 mmHg. The measurement time was 61 seconds faster on average than the automatic blood pressure monitor. Finally, the manual blood pressure monitor palpation on the sharp curve road showed a systolic pressure deviation of 5 mmHg. The automatic blood pressure monitor had one reading failure and the measured systolic pressure deviation was 21 mmHg. The measurement time showed that the manual blood pressure monitor was 101 seconds faster than the automatic blood pressure monitor. As a result, in a moving ambulance during an emergency, the manual blood pressure monitor showed high reliability because the blood pressure measurement was constant and the measurement time was short.

Purpose: The aim of this study was to provide basic data to improve the survival rate of pre-hospital cardiac arrest patients. This study suggests a more effective method of performing effective chest compressions for a cardiac arrest patient in a moving ambulance. Methods: To compare the differences between gender and license (qualification), SPSS 18.0 (Windows) was used. Independent and paired t-tests were used for differences between before and after wearing a rescuer's belt. Results: The success rate of chest compressions according to gender was higher in males ($68{\pm}21.91%$) than in females ($25.04{\pm}16.88%$). There was no difference according to license ($44.70{\pm}26.63$ for paramedic, $45.05{\pm}19.25$ for nurse). However, the depth (mm) and the success rate (%) were improved during the evaluation of chest compressions when wearing the rescuer's belt (depth: $46.95{\pm}6.49$ vs. $49.55{\pm}6.05$, success rate: $44.80{\pm}24.66$ vs. $57.39{\pm}26.823$). Conclusion: Wearing a rescuer's belt in an ambulance during patient transport can result in deeper and more accurate chest compressions; therefore, it is expected to be effective in recovering the circulation of patient with cardiac arrest.

Tele-medicine and emergency medical system are necessary for moving from an accidental point or far distance to a hospital and emergency treatment or home treatment before a hospital. Emergency treatment is extremely important in the case of death before arriving a hospital and deformed or disabled by medical treatment delay. A necessary element for this medical system is the emergency communication system. This system is on preparing for an ability of furnishing patient status to a corresponding health service by monitoring the patient at an ambulance of the accident place. This is the transportation of basic biological information of a patient to a medical center by wireless communication system and the corresponding hospital or medical center examine the patient by monitoring, then they can send emergency medical order to the patient for emergency treatment. The TRS is most efficient way of emergency medical communication system, which is currently used with popularity. In this paper studied simultaneously a way of detecting and transporting bio-logical signals, and monitoring of transporting data with communication of voice in the accident place or ambulance.

Purpose: The study aims to provide basic data to enhance the health of paramedics responsible for patient transport and treatment by analyzing the exposure level of paramedics to electromagnetic waves generated by electric devices used in ambulances. Methods: The study measured electromagnetic waves in ambulances in N region from July to December 2018. ME3030B produced by German Gigahertz Solutions was used to measure these waves and the maximum value was selected by moving it slowly in various directions. Each measurement part was selected and the mean value was calculated by repeatedly measuring at 10-minute intervals three times in total: $1^{st}$, $2^{nd}$, and $3^{rd}$ phase. Results: Among the electrical devices installed in the patient room of the ambulance measured at distances of 1 cm or 30 cm, results showed a high level of electric waves at the inverter ($26.25{\pm}39V/m$) and high level of electromagnetic waves ($564.00{\pm}31.75nT$) at the ozone sterilizer. According to measurements toward the front near the driver's seat, results indicated high levels of electric waves ($3.67{\pm}1.15V/m$) and electromagnetic waves ($450.00{\pm}19.52nT$) at the black box hard drive. Conclusion: Electromagnetic waves within the ambulance were stable and not beyond the range that might impact human health. However, in the case of the black box hard drive ($3.67{\pm}1.15V/m$, $450.00{\pm}19.52nT$) located under the passenger seat, it may have a direct effect on the human body and, thus it is necessary to move it to a storage area further away from the paramedics to minimized the impact.

The radiologic imaging device was implemented. It can be installed in an ambulance or used when an accident happens. After an equipment which generates X-ray generating unit with a tube in DC 12[V] had been made, a trait experiment using an oscilloscope was made. An experiment was carried out where the generated X-ray was saved as a form of a file using a digital detector. In this experiment, as a result of generating X-ray and detecting it using a digital detector, 1.67[MB]-, jpg- radical rays information could be saved. One distinct advantage of the developed radiologic imaging device is the fact that we can efficiently deal with emergency cases too far from the hospital, difficult to diagnose but treat simultaneously. By using the radiologic imaging device at the urgent scene of an accident or in a moving ambulance, we can provide the patient's X-ray information with the emergency medical specialist who is in the emergent medical center and have the patients prescribed and treated appropriately. As a result the developed emergency medical treatment can be expected.

The purpose of this study was to improve the paramedics skills to manage advanced airway by comparing speed and success rate between endotracheal intubation and laryngeal mask airway(LMA) insertion in a moving ambulance. Sixty subjects were randomly recruited and samely divided into control group and experimental group. And they were asked to join a practical experiment using dummy model. Data analysis was done by SPSS WIN 14.0 Version. As a result of this research, in terms of difference in speed according to patient's intubation posture, the speed of control group was indicated to be good in sniffing position(t=-4.038, p<.001). There was no difference in speed between two groups in neutral position. In the neutral posture given the endotracheal intubation, tooth fracture occurred in 16 people(53.3%). There was no difference in success rate between two groups. As for a change in self-confidence before and after experiment, the post self-confidence was indicated to have been enhanced in both groups. In conclusion, it is effective to use LMA in the traumatic patient who is unable to receive endotracheal intubation in sniffing position. It is very important for the paramedics to receive the continuous training of the airway management skills.
