Physio Control Lifepak 12

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
• Semi-automatic defibrillation
• Noninvasive pacemaker
• Pulse oximeter
• Interpretive 12-lead ECG
• Noninvasive blood pressure (NIBP) monitor
• End-tidal CO2 (EtCO2) monitor

• Vital sign (VS) and ST monitoring
• Fax transmission
• Paddle accessories
