Detection of congestion from monitoring patient response to a recumbent position
First Claim
1. A method comprising:
- monitoring a patient over a period of time with at least one device, wherein the at least one device monitors time while detecting whether the patient is in a recumbent position to compute an amount of recumbent time, during the period, for which the patient is in the recumbent position; and
determining whether the patient is suffering from congestion by using the amount of recumbent time.

Abstract
Systems and methods obtain information that allows detection of whether a patient suffers from congestion by monitoring a response of the patient to a recumbent position of the patient'"'"'s body. The patient may be monitored to determine a respiration pattern for a non-recumbent position such as standing and a respiration pattern for a recumbent position such as lying down. The two patterns may be compared, either by a processing device or a physician, to determine a difference in the two respiration patterns. Furthermore, the congestion may be inferred from detecting an amount of time that the patient spends in a recumbent position or from detecting the recumbent angle that the patient obtains, either of which is presumed to indicate whether a recumbent position presents discomfort to the patient due to the presence of congestion.

9. A system comprising:
-
a reclination sensor that produces a signal indicative of a reclination of the patient; reclination circuitry that produces reclination data from the reclination signal; a clock that produces at least one timing signal; a memory; and a processing device that is configured to communicate with the reclination circuitry and clock to determine, from the reclination data and timing signal, an amount of recumbent time for which the patient is in a recumbent position, to compare the amount of recumbent time to a threshold value, and to determine, using a result of the comparison, whether a patient is suffering from congestion. - View Dependent Claims (10, 11, 12, 13, 14, 15)
