Abstract

A defibrillator having infrared communication capability is provided. The wireless communications capability is implemented using infrared light or RF communications and standardized communications protocols such as the IrDA protocol to allow for ready communication between defibrillators such as during handoffs of patient along the Chain of Survival. The wireless communications network also allows for communications between a defibrillator and a host computer such as a palmtop for incident report generation after each handoff. Another embodiment of the present invention provides for a defibrillator having an infrared mode switch to allow for restricted access to advanced cardiac life support (ACLS) features of the defibrillator. A further embodiment of the present invention provides for a defibrillator having a remote training mode that is implemented via wireless communications. Another embodiment of the present invention provides for a defibrillator test system that is implemented via wireless communications. A further embodiment of the present invention provides for a live ECG telemetry data link using the wireless communications system.

Claims
