DEFIGARD/PHYSIOGARD Touch 7
The
DEFIGARD
®
Touch 7
SAS test has been completed with a validation database
consisting of 2,475 couples of ECG and transthoracic Impedance Cardiogram (ICG)
from out-of-hospital cardiac arrest (OHCA) interventions, recorded with Automated
External Defibrillators (FredEasy, Schiller Medical SAS, France) used by the fire
brigade of Paris.
This supplementary test completes the validation of both SAS configurations and
provides performance fully in accordance with these summarized in Table 1. A report
of the global validation test results is available on request.

Deviating from the compliance statement according to 201.108.1.10 (IEC60601-2-
4, 201.1.108.7. and 201.1.108.6), the following features have been measured for the
universal electrode:
80 cm2 active surface
• For up to 1 hour of pacing using 140mA / 120ppM (pulse duration 20ms)
• For up to 8 hours of pacing using 70mA / 60ppM (pulse duration 20ms) inspection
of pads every 30 minutes
