The aim of the study was to analyze the cardiac compression force us-ing the vertical force with normalized (100%) in cardiopulmonary resus-citation. Nineteen subjects with basic life support license and instructor career participated in this study. Cardiac compression was performed in a situation positioned practical manikin on ground reaction force and with 1,000 Hz of sample rate. Cardiac compression force in vertical di-rection showed significant difference among 30 times cardiac com-pression. Vertical cardiac compression force (N) showed significant difference according to the 30 times of cardiac compression in each di-astole (45.79 N) and systole (714.38 N) phase. Also, normalized vertical force showed significant difference according to the 30 times cardiac compression in each diastole (6.80%) and systole (93.20%) phase. This suggests that there is a greater difficulty in performing diastole forces close to 0% than performing a sufficient maximal cardiac compression force in cardiopulmonary resuscitation.
