Indicating the status of an energy storage device of a medical device
First Claim
1. A method comprising:
- storing, by a medical device that delivers therapy to a patient, a value that indicates an estimated number of therapy delivery events available from the medical device;
periodically estimating an amount of energy stored by an energy storage device of the medical device;
periodically estimating a number of therapy delivery events available from the medical device based on the estimated amounts of stored energy to produce updated estimates;
periodically updating the stored value based on the updated estimates; and
presenting the stored value to a user.

Abstract
The disclosure describes a medical device that provides an indication of the status of an energy storage device from which it receives power. For example, the medical device may provide an estimate of the number of therapy delivery events available from the medical device based on an estimate of the amount of energy stored in the energy storage device. The medical device may be an external defibrillator, and the therapy delivery events may be defibrillation shocks. Additionally or alternatively, the medical device may indicate an estimated amount of operational time remaining in each of a plurality of monitoring modes based on the estimated amount of stored energy. The energy storage device may be a battery. An energy storage device that itself provides an indication of its status is also disclosed.
