Medtronic, Physio Control Lifepak 500

Unit Only No Battery The features and configurability of the LIFEPAK 500 make
it user-friendly.
Its technology makes it a proven life-saver. Like all AEDs,
this one talks you through the rescue. But that's just the start.
It also has an LCD display so you can read the instructional prompts
if background noise prevents you from hearing them.
The device uses Physio-Control's escalating biphasic electrical waveform.
This means the AED will escalate its energy output if the patient's situation demands it.
(All LIFEPAK AEDs have this feature.)
The AED tests itself regularly and the readiness indicator displays the machine's status.
You don't have to turn the AED "on" or do anything else to know if it's ready-to-use.
The LIFEPAK 500 gives you choices in configurations to help make a future rescue easy.
For example, depending on the method of CPR you've been taught, you can program the device to prompt for pulse checks.
You can change the timing of CPR interval in case the "rules" of CPR ever change
in the future (again!).
You can program an instruction to perform CPR while the AED is charging
Medical professionals can activate an asystole detector, too.
Electronically assign a unique device ID to the LIFEPAK 500 so you won't have
to put labels, stickers, or magic marker identifiers on your AED.
You can do all of this without the need to buy reconfiguration software packages
or computer peripherals. The only optional software you may want to consider
is to download post-event patient data from the device if needed.
