ADAPTIVE SELF-TESTING AND STRESS ANALYSIS OF MEDICAL DEVICES

摘要

An improved self-testing method is described which is incorporated into a defibrillator (20). The method performs a self-testing protocol which operates on a first frequency until a threshold condition is reached. When the threshold condition is reached, the self-testing protocol switches to a second frequency. Such a method enables quicker identification of a failure mode in a population of defibrillators, while maintaining acceptable battery life in the device.

主权项

1. A method for self-testing a defibrillator, comprising the steps of:
periodically performing a self-test protocol at a first frequency; detecting a condition which exceeds a threshold condition; automatically switching the self-test protocol to a second frequency responsive to the detecting step; and periodically performing the self-test protocol at the second frequency, wherein the first frequency is higher than the second frequency.
