Method for Presenting Current and Stored ECG Waveforms on a Portable, External Defibrillator

Abstract

A method of simultaneously presenting current and stored ECG waveform data on a portable, external defibrillator during a rescue. The stored ECG waveform data may also be used in a rescue or training exercise.

         29 . A method of displaying ECG waveforms on a portable, exterior defibrillator comprising the steps of:
 providing a portable, exterior defibrillator comprising a video display, a memory, a user “off” state, and a user “on” state;   initiating a rescue attempt by turning the portable exterior defibrillator to the user “on” state;   obtaining a current ECG waveform from a source;   storing the obtained current ECG waveform in the memory, creating a stored ECG waveform; and   simultaneously displaying on the video display the current ECG waveform and some portion of the stored ECG waveform.   
     
     
         30 . The method of  claim 29  further including the step of connecting the defibrillator to a victim by a set of pads whereby the source of the current ECG waveform is the victim. 
     
     
         31 . The method of  claim 29  whereby the source of the current ECG waveform is a simulator. 
     
     
         32 . A method of displaying ECG waveforms on a portable, exterior defibrillator comprising the steps of:
 providing a portable, exterior defibrillator comprising a video display, a memory, a user “off” state, and a user “on” state;   initiating a rescue attempt by turning the portable exterior defibrillator to the user “on” state;   storing an ECG waveform in memory;   obtaining a current ECG waveform from a source generating an ECG waveform; and   simultaneously displaying on the video display the current ECG waveform and some portion of the stored ECG waveform.   
     
     
         33 . The method of  claim 32  wherein in the step of storing an ECG waveform, the ECG waveform is obtained from a library. 
     
     
         34 . The method of  claim 32  comprising the further step of connecting the defibrillator to a simulator, and in the step of obtaining a current waveform, the source is the simulator. 
     
     
         35 . The method of  claim 34  wherein in the step of storing an ECG waveform, the stored ECG waveform is obtained from the simulator. 
     
     
         36 . The method of  claim 32  comprising the further step of connecting the defibrillator to a victim by a set of pads, and in the step of obtaining a current waveform, the source is the victim. 
     
     
         37 . The method of  claim 36  wherein in the step of storing an ECG waveform, the stored ECG waveform is obtained from the victim.
