Objectives: The purpose of this study was to investigate physiological changes of emergency medical technology students after diving education for water lifeguards. Methods: The study subjects were 14 emergency medical technology students who have completed a preliminary course only in confined water. Open water dives were performed from 9-11, July, 2010 in Geomundo, Yeosu, Jeollanamdo. The data were collected from questionaries, vital sign checks and hematologic exams. Vital sign checks (heart rate, blood pressure and saturation) and hematologic exams were undergone before and after diving. Wilcoxon’s signed rank test and Mann-Whitney U test were performed to examine the physiological changes by diving education. Results: The levels of hematocrit, hemoglobin, red blood cell and cortisol significantly increased after diving (p<0.05). On the other hand, there were no significant differences in vital signs and the results of other hematologic exams. Additionally, some differences in physiological changes were showed according to sex, smoking status and obesity. Especially, the cortisol level by obesity and Hct and Hb by smoking status were different. Conclusion: Some physiological changes were observed after diving education for water lifeguards in emergency medical technology students. When diving education is performed, subjects’ characteristics such as smoking and obesity should be considered. These results will help to train the emergency medical technology students. A further study with a larger sample is needed to be conducted.
