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:
- at least one connection port disposed on the defibrillator capable of connecting with a plurality of electrodes, the electrodes being capable of being attached to a patient so as to provide patient data to the defibrillator;
an input device disposed on the defibrillator;
an output device disposed on the defibrillator; and
a controller disposed in said defibrillator, said controller coupled to said connection port, said input device, and said output device, and wherein said controller is also configured to;
receive an activation command from an emergency medical service (EMS) center;
start a timer function upon receiving the activation command;
sample an elapsed time from the timer function;
compare the elapsed time to a set time;
order a CPR protocol if the elapsed time is greater than the set time; and
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.
