Medtronic – Lifepack 12

Description

The Physio-Control Lifepak 12 is a defibrillator/monitor with pacing options. The Lifepak 12 offers both manual and semi-automatic external defibrillation monitors along with an Add mode. The defibrillator comes with a Shock advisory system to help detect rhythm for shocking, along with a simple 1-2-3 operation. With a large LDC screen, 3 ECG channels can be simultaneously viewed with up to 8 seconds of cascading ECG. Additionally, the Lifepak 12 can also monitor parameters such as heart rate, pulse oximetry, oxygen, blood pressure, and additional vital.

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
