Physio-Control Lifepak Features
The Physio-Control Lifepak 12 defibrillator/monitor, when in AED mode, is a semiautomatic defibrillator that uses a patented Shock Advisory System. This software algorithm analyzes the patient’s electrocardiographic (ECG) rhythm and indicates whether or not it detects a shockable rhythm. The Lifepak 12 defibrillator/monitor in AED mode requires operator interaction in order to defibrillate the patient.
The Lifepak 12 defibrillator/monitor offers the following optional features:
Biphasic defibrillation waveform
Interpretive 12-lead ECG
Noninvasive blood pressure (NIBP) monitor
End-tidal CO2 (EtCO2) monitor
Invasive pressure (IP) monitor
The vital sign (VS) and ST monitoring
Lifepak 12 Paddle accessories
Electroluminescent (EL) display (The optimal viewability of an EL display is compromised in direct sunlight.)

Vital Signs Summary
ECG on the Lifepak 12 is monitored via several cable arrangements. A 3-wire cable is used for 3-lead ECG monitoring. A 5-wire cable is used for 7-lead ECG monitoring. A 10-wire cable is used for 12-lead acquisition. When the chest electrodes are removed, the 10-wire cable functions as a 4-wire cable. Standard paddles or QUIK-COMBO pacing/defibrillation/ ECG electrodes or FAST-PATCH disposable defibrillation / ECG electrodes are used for paddles lead monitoring.
