The 500 offers waveforms with the capability to deliver shocks at energy levels recommended by the American Heart Association and European Resuscitation Council.

Features include pre-connected QUIK-COMBO electrodes that save valuable time on-scene and are compatible with other LIFEPAK defibrillators; clear, concise voice prompting for defibrillation and CPR; LCD for text messages; shock count; CPR time; and real-time clock. Choice of simple 2- or 3-button operation allows the 500 to meet the needs of responders with a variety of training and experience levels. Automatic self-testing saves time and improves testing consistency. Always visible readiness display (available on devices with 3D biphasic Technology only), accompanied by an audible tone, provides SERVICE REQUIRED or LOW BATTERY alert. Battery options include a rechargeable sealed lead-acid battery and a high capacity extended shelf-life lithium battery that requires no recharging and no maintenance.

ECG data and on-scene audio (optional) are stored digitally within the device for maximum durability and simplicity. Incident data can be conveniently transmitted from the 500 to medical control via modem. CODE SUMMARY reports can be printed directly to a standard printer for rapid access to information. User-friendly PC-based software allows complete, efficient review of both ECG and audio data. LIFEPAK 500 data can be stored in a CODE-STAT database with other Medtronic Physio-Control defibrillator and 12-lead data for comprehensive system-wide review and reporting.
