WET & METAL SURFACES
TESTING
To confirm there would be no effect on the user, Philips has simulated a 150J SMART
Biphasic shock to a patient on a wet concrete surface using chlorinated pool water.
voltages created in the water were tested at various points away from the simulated patient
to verify that no danger existed to the user. This grid below shows the leading edge peak
voltage (in Volts) recorded during a defibrillation shock measured at each location on the
grid.
