The effect of liquid between the electrode pads of AED(automated external defibrillator) on the output energy has been investigated by using the tap water, physiological saline water, and 3.5% NaCl water solution. The decrease in voltage, shorting of output time, and reduction of output energy were observed when the pathway was built up by physiological saline water or 3.5% NaCl water solution. In the case of the tap water and droplet of physiological saline water or 3.5％ NaCl water solution, the remarkable change in the output voltage and energy were not observed. These results mean that the energy loss is negligible small if the pathway does not exist between the electrode pads of AED. Thus we need to wipe the liquid on the surface of patient in order to remove the pathway of it when the BLS is performed for the wet patient.
