DETECTION OF CONGESTION FROM MONITORING PATIENT RESPONSE TO A RECUMBENT POSITION
First Claim
1. A system, comprising:
- a reclination sensor that produces a reclination signal indicative of a reclination of a patient;
reclination circuitry that produces reclination data from the reclination signal;
a respiration sensor that produces a respiration signal indicative of respiration patterns of the patient;
respiration circuitry that produces respiration pattern data from the respiration signal; and
a processing device that is configured to communicate with the reclination circuitry and the respiration circuitry to determine, from the reclination data and the respiration pattern data, recumbent respiration pattern data and non-recumbent respiration pattern data, to compare the recumbent and non-recumbent respiration pattern data, and to determine, using a result of the comparison, whether the patient is suffering from congestion.

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.
