Medical device with resuscitation prompts depending on elapsed time
First Claim
1. An external defibrillator for providing a selected treatment protocol to a patient comprising:
- a connection port capable of receiving electrodes, the electrodes being capable of being attached to a patient so as to provide patient data to the defibrillator; and
a controller coupled to the connection port, and configured to;
receive an activation command that has been generated externally from the defibrillator,start a timer function responsive to the received activation command,sample an elapsed time from the timer function, andorder a CPR protocol if the elapsed time is greater than a set time, else order a shock treatment protocol if the elapsed time is less than the set time.

Abstract
Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator using a measurement of elapsed time. The present invention provides a defibrillator with a timer function. Upon activation of the defibrillator, an internal timer begins to run. By closely associating the activation of the defibrillator with the onset of the patient'"'"'s attack, and by making allowances for inherent time differences between these events, the timer provides a measure of the elapsed time between the onset of the patient'"'"'s emergency and the presentation of the defibrillator at the patient'"'"'s side. Using this measure of elapsed time, the defibrillator determines an appropriate treatment therapy, such as CPR or defibrillation therapy.
