Methods and devices for detection of context when addressing a medical condition of a patient
First Claim
1. A system for monitoring physiological conditions of an ambulatory patient capable of moving among a plurality of environmental locations external to the patient based on a detection of at least one posture associated with the patient, the system comprising:
- a detector, including a first device positioned in one of the plurality of environmental locations and a second device attached to the ambulatory patient, the first and second devices configured to cooperate to detect the patient being within a specified range of the first device and to determine the at least one posture associated with the patient in response to the patient being within the specified range of the first device;
a physiological sensor that is responsive to a physiological condition of the patient; and
a processing device configured to automatically measure from the physiological sensor at least one physiological condition of the patient in response to the detection of the at least one posture.

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.
