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:
- measuring at least one physiological condition of the patient with an implanted medical device;
associating a non-clinical location with a contextual condition for the patient that is relevant when measuring the at least one physiological condition of the patient, wherein the non-clinical location is one of the plurality of non-clinical locations to which the ambulatory patient is capable of moving; and
while measuring the at least one physiological condition, utilizing the implantable medical device for sensing an external device in the non-clinical location and determining that the contextual condition associated with the non-clinical location exists when the patient is within a range of the external device and the implantable medical device senses the external device; and
flagging with a first indicator one or more measurements resulting from the measuring done while the contextual condition continues to exist.

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.

10. A system for monitoring physiological conditions of a patient, comprising:
-
a transmitter external to the patient and in a predetermined location associated with at least one contextual condition; a detector adapted to detect whether the detector is within a range of the transmitter to detect the at least one contextual condition; an implanted physiological sensor adapted to sense a physiological condition of the patient inside and outside of the range; and a processing device configured to communicate with the implanted physiological sensor to measure at least one physiological condition of the patient, to determine if measurements from the implanted physiological sensor were taken when the detector detects the at least one contextual condition, and to flag the measurements taken when the detector detects the at least one contextual condition. - View Dependent Claims (11, 12, 13)

14. A method of monitoring physiological conditions of an ambulatory patient who is capable of moving to a plurality of non-clinical locations, comprising:
-
measuring at least one physiological condition of the patient with a measurement device while the patient is in non-clinical locations; while measuring the at least one physiological condition, utilizing the measurement device for sensing that an external device is within a range and for detecting whether at least one contextual condition associated with the patient exists, the external device in a predetermined location associated with the contextual condition, the external device for emitting a signal from the predetermined location, wherein utilizing the external device includes using the measurement device for detecting the signal emitted by the external device and for determining that the measurement device is proximal to the predetermined location and that the at least one contextual condition exists when the signal from the external device is detected; and flagging with a first indicator one or more measurements resulting from the measuring done while the signal is received by the measurement device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
