This is a cross-sectional study intended to draw the effectiveness of dispatcher-based voice-direction and video-direction at an advance stage of a hospital in order to draw a more effective CPR directing method between the previous phone CPR direction and the new and active dispatching method-based voice-direction and video-direction. 80 fire officers working at the fire headquarters in Daejeon participated in the study. While it was average 4.28 for voice-direction, it was 6.23 for video-direction, which showed that video-direction had the significantly higher performance than voice-direction in managing the airway. Voice-direction was average 3.73, whereas video-direction was average 6.15 in performing CPR as well, which showed that video-direction had statistically more positive outcomes than voice-direction. The result of the cardiac massage was also showed that voice-direction was average 4.90 whereas video-direction was average 6.55, which showed a statistically significant difference proving that videodirection had better outcomes than voice-direction. However, it was 17.62% for voice-direction and 18.68% for video-direction in the basic respiration accuracy without a statistically notable difference between them. For pressure accuracy of the cardiac massage, it was average 47.33% for voice-direction and average 77.43% for video-direction implying that video-direction had the higher pressure accuracy than voice-direction. For the time took for respiration and pressure, video-direction had a reduced performance time compared to voice-direction.
