A system for obtaining information related to congestion of a patient, comprising; a reclination sensor configured to produce a reclination signal indicative of the reclination of the patient; detection circuitry configured to produce reclination data from the reclination signal; a respiration sensor configured to produce a respiration signal indicative of respiration patterns of the patient; respiration circuitry configured to produce respiration pattern data from the respiration signal; and a processing device configured to: monitor the respiration pattern data and the reclination data, determine whether the patient is in a recumbent position by comparing the reclination data to data representative of a reclination threshold, associate the respiration pattern data obtained at a point in time with the reclination data obtained at the point in time, characterised in that: the processing device is configured to: compare the respiration pattern data obtained when the patient is in a recumbent position to the respiration pattern data obtained when the patient is in a non-recumbent position to detect whether a difference is present between the respiration patterns associated with recumbent and non-recumbent positions; and in response to differences between the respiration patterns associated with recumbent and non-recumbent positions, to determine whether the patient is suffering from congestion. monitor the respiration pattern data and the reclination data, determine whether the patient is in a recumbent position by comparing the reclination data to data representative of a reclination threshold, associate the respiration pattern data obtained at a point in time with the reclination data obtained at the point in time, characterised in that: the processing device is configured to: compare the respiration pattern data obtained when the patient is in a recumbent position to the respiration pattern data obtained when the patient is in a non-recumbent position to detect whether a difference is present between the respiration patterns associated with recumbent and non-recumbent positions; and in response to differences between the respiration patterns associated with recumbent and non-recumbent positions, to determine whether the patient is suffering from congestion. the processing device is configured to: compare the respiration pattern data obtained when the patient is in a recumbent position to the respiration pattern data obtained when the patient is in a non-recumbent position to detect whether a difference is present between the respiration patterns associated with recumbent and non-recumbent positions; and in response to differences between the respiration patterns associated with recumbent and non-recumbent positions, to determine whether the patient is suffering from congestion. compare the respiration pattern data obtained when the patient is in a recumbent position to the respiration pattern data obtained when the patient is in a non-recumbent position to detect whether a difference is present between the respiration patterns associated with recumbent and non-recumbent positions; and in response to differences between the respiration patterns associated with recumbent and non-recumbent positions, to determine whether the patient is suffering from congestion.
