Methods and devices for detection of context when addressing a medical condition of a patient
First Claim
1. A method of monitoring physiological conditions of an ambulatory patient who is capable of moving to a plurality of non-clinical locations, comprising:
- associating a predetermined location with a contextual condition for the patient that is relevant when measuring at least one physiological condition of the patient;
operating an implanted medical device in the patient to monitor the at least one physical condition of the patient in non-clinical locations, including;
using the implanted medical device in the patient to sense for a beacon from an external device that is positioned in the predetermined location and that transmits the beacon from the predetermined position before the patient is within range for the implanted medical device to sense the beacon transmitted from the predetermined location;
determining that the implanted medical device is not within range of the beacon if the beacon is not sensed;
determining that the implanted medical device is within the range of the beacon and that the contextual condition exists when the beacon is sensed; and
automatically measuring the at least one physiological condition of the patient using the implanted medical device in response to determining that the implanted medical device is within the range of the beacon and that the contextual condition exists.

Abstract
Methods and devices detect context related to a patient when monitoring a physiological condition of the patient and/or when applying one or more modes of therapy. The context may be a patient context such as posture or an environmental context such as ambient conditions. The context may be used in various ways in relation to the physiological measurement, such as to control when the physiological measurements are made, to appropriately flag physiological measurements, to be recorded in association with the physiological measurements, and/or to correct the physiological measurements based on a reference context. A device such as a beacon transmitter is used in detecting the context and a measurement device such as an implantable cardiovascular device is used to capture the physiological measurements.

7. A method of monitoring physiological conditions of an ambulatory patient, comprising:
operating an implanted measurement device, including; measuring at least one physiological condition of the patient using the implanted measurement device; sensing for a beacon transmitted by an external device from a predetermined location that is associated with a contextual condition for measuring the at least one physiological condition; determining that the implanted measurement device is within a transmission range of the external device and that the contextual condition for operating the implanted measurement device exists when the beacon is sensed, and determining that the implanted measurement device is not within the transmission range of the external device when the beacon is not sensed; and correlating the measurements of the at least one physiological condition with the contextual condition. - View Dependent Claims (8, 9, 10, 11, 12)

13. A device for monitoring physiological conditions of a patient, comprising:
-
a detector adapted to detect a beacon transmitted by an external device located in a predetermined location, the beacon being an indicator of a contextual condition associated with the patient; an implanted physiological sensor adapted to sense a physiological condition of the patient; and a processing device configured to operate in a first mode if the beacon is detected, operate in a second mode if the beacon is not detected, and measure at least one physiological condition of the patient using the sensor, wherein the processing device is configured to automatically flag physiological conditions that were measured when the beacon is detected when operating in the first mode. - View Dependent Claims (14, 15, 16)

17. A system for monitoring physiological conditions of a patient, comprising:
an implanted measurement device, including; means for measuring at least one physiological condition of the patient; means for detecting a beacon transmitted by an external device from a predetermined location, including means for identifying a value for patient context from the beacon; and means for correlating the measurements of the at least one physiological condition with the value for the patient context. - View Dependent Claims (18, 19, 20, 21, 22)
