Abstract
In an implantable medical device and method for monitoring a lung deficiency in a patient, a housing containing a control circuit. Is implanted in a patient. The control circuit is configured to analyze one or more signals that represent the breathing of the patient. The control circuit is also configured to monitor a relationship between an expiratory phase and an inspiratory phase of the breathing cycle, or an analogous relationship, and to monitor a change in the lung deficiency by monitoring a change in this relationship.

25. An implantable medical device comprising:
-
a housing adapted for implantable in al living subject; a control unit contained within said housing, said control unit being supplied with at least one signal representing respiration, comprising a plurality of breathing cycles, of the living subject; and said control circuit being configured to monitor a relationship, as represented in said at least one signal, between an expiratory phase and an inspiratory phase of the breathing cycle, and to monitor a change in said relationship and to provide a control circuit output representing a change in lung deficiency of the living subject dependent on said change in said relationship. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 42, 43, 44, 45, 46, 47, 48, 49, 50)

35. An implantable medical system comprising:
-
a housing configured for implantation in a patient; at least one medical lead adapted for implantation in the patient; a control circuit in said housing connected to said at least one medical lead to receive an input signal therefrom representing breathing, in a breathing cycle, of said patient; a therapy administration circuit that generates a therapy, according to a therapy regimen controlled by said control circuit, said therapy generating circuit being connected to said medical lead and delivering said therapy via said medical lead; said control circuit being configured to monitor a relationship, represented by said input signal, between an inspiratory phase and an expiratory phase of the breathing cycle to monitor a change in lung deficiency by monitoring a change in said relationship, and to modify said therapy regiment dependent on said relationship. - View Dependent Claims (36, 37, 38, 39, 40, 51, 52)

41. A method for monitoring lung deficiency in a patient, comprising the steps of:
-
implanting a device within the patient; in said device, automatically analyzing at least one signal representing breathing, in a breathing cycle, of the patient; in said device, automatically monitoring a relationship between an expiratory phase and an inspiratory phase of said breathing cycle; and in said device, monitoring a change of said relationship and emitting a signal representing a change in lung deficiency of the patient dependent on said change in said relationship.
