7.1.4 Waveform Specifications

The RESCUE SAM delivers a nominal 200J Biphasic Truncated Exponential waveform to patients with
impedances ranging from 25 to 175 ohms.
The waveform is adjusted to compensate for measured patient impedance. Nominal phase times and
energy delivered are shown in the tables below.

7.1.5 Patient Analysis System
The RESCUE SAM Patient Analysis System ensures that the pad/patient impedance is within the proper
range and analyzes the patient's ECG rhythm to determine whether a shock is required. In an initial ECG
signal conditioning stage, ECG data are received and digital processing is done to remove baseline
wander and high-frequency noise.
The ECG signal are then processed by the ECG signal analysis routines. The arrhythmia detection process
determines whether or not to advise shocking the patient by examining the outputs of these analyses.

Shock is delivered by a single SHOCK
button
If Patient Analysis System decides
rhythm is no longer shockable, or
within 15 seconds after Charge
complete, if operator has not pressed
SHOCK button, or if defibrillation pads
are removed from patient or unplugged
from unit.
• If operator presses the OFF/DISARM
button at any time to disarm and turns
off the device.
