Physio-Control Lifepak 500 Features

The Physio-Control Lifepak 500 is a portable, battery-powered automated external defibrillator. Once the Electrode pads are attached to the patient, the defibrillation system can evaluate the heart rhythm and detect if a shock is needed. The Physio-Control Lifepak 500 comes in both Monophasic and biphasic modes. The Lifepak 500 is an AED that offers both vocal and visual step-by-step instructions on how to use the defibrillator. The two-button operation system makes it easy to use, with an on/off button and a shock button. Like most defibrillators, the Lifepak 500 runs a self-test every 24 hours making sure the system is running properly and is ready when needed.

  • Simple 2 or 3-button operation
  • Low maintenance
  • Durable
  • Powerful
  • User-friendly
