Methods and apparatus for manually suspending intrathoracic impedance fluid status measurements
First Claim
1. A method of selectively deactivating a notification function in an implantable medical device (IMD), comprising:
- monitoring a physiologic parameter of a patient indicative of the patient'"'"'s intrathoracic fluid status;
determining when the physiologic parameter one of exceeds a threshold and departs from a desired range;
energizing the notification function of the IMD responsive to a determination that the physiologic parameter one of exceeds a threshold and departs from a desired range;
receiving corrective or palliative therapy from a clinician subsequent to the determination that the physiologic parameter one of exceeds a threshold and departs from a desired range; and
deactivating the notification function of the IMD for a preset period of time responsive to receipt of the corrective or palliative therapy.

Abstract
The capability to suspend a patient alert relating to a monitored physiologic parameters addresses a need to selectively shut off a patient-alert signal or signals during the time a patient is being treated for an excursion in the parameter. Of course, in general a signal call attention to a patient'"'"'s a potentially deleterious status or condition for which they should seek medical attention. Once a chronically-implanted monitoring device has detected or provided information about the parameter relative to a desired value, trend, or range and a clinician has been notified and intervened the alert signal is temporarily disabled for a predetermined period. That is, once the notification occurs and alert has served its purpose, the alert mechanism is selectively deactivated while the patient ostensibly begins to gradually correct the monitored physiologic parameter under a caregiver'"'"'s direction and control. After which time, the alert will reactivate.
