Systems and methods of determining location using a medical device

A method of tracking movement of a medical device comprising:

• receive, at a processor of the medical device, movement information comprising at least acceleration information and heading information from at least one motion detector of the medical device;
• detect, by the processor, movement of the medical device based on the movement information, wherein the movement of the medical device comprises a distance traveled by the medical device and a direction traveled by the medical device;
• and
• estimate, by the processor, a current location of the medical device relative to a previous location of the medical device using dead reckoning based at least in part on the distance traveled by the medical device and the direction traveled by the medical device.

A system comprising:

• at least one wireless access point;
• a medical device for assisting treatment of a patient, the medical device comprising:
• a sensor interface for measuring one or more physiological signals of the patient;
• at least one motion detector for detecting movement of the medical device;
• a processor coupled to the sensor interface, and the at least one motion detector;
• and
• a memory communicatively coupled to the processor and comprising instructions that when executed by the processor cause the processor to:
• determine a previous location of the medical device based at least in part on a signal received from the at least one wireless access point;
• receive movement information comprising at least acceleration information and heading information from the at least one motion detector;
• detect movement of the medical device from the movement information received from the at least one motion detector, wherein the movement of the medical device comprises a distance traveled by the medical device and a direction traveled by the medical device;
• and
• estimate a current location of the medical device relative to the previous location of the medical device using dead reckoning based at least in part on the distance traveled by the medical device and the direction traveled by the medical device.
