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

1. An apparatus for transmitting live ECG signals, comprising:

a defibrillator, including a wireless communication unit, for coupling to a patient to acquire said live ECG signals;

a radio telemetry link provided by said wireless communication unit to receive said live ECG signals; and

a computer coupled to said radio telemetry link to display said live ECG signals,

wherein said defibrillator automatically configures said radio telemetry link to said computer.

2. An apparatus for transmitting live ECG signals according to claim 1 wherein said live ECG signals are displayed on said computer as a web page.

3. An apparatus for transmitting live ECG signals according to claim 1 wherein said live ECG signals are displayed on said computer as a fax page.

4. An apparatus for transmitting live ECG signals according to claim 1, said defibrillator comprising:

an ECG front end;

a pair of electrodes, coupled to sand ECG front end, for placement on said patient to acquire said live ECG signals; and

a controller coupled to said ECG front end to receive said live ECG signal and send said live ECG signal to said wireless communication unit.

5. An apparatus for transmitting live ECG signals according to claim 1 wherein said defibrillator sends a call set up to said radio telemetry link responsive to an initiate link command.

6. An apparatus for transmitting live ECG signals according to claim 1 wherein said wireless communication unit comprises an infrared communication unit.

7. A defibrillator test system according to claim 6 wherein said infrared communication is sent according to an IrDA protocol.

8. A defibrillator test system according to claim 1 wherein said wireless communication comprises RF communication.
