Therapy Control Based on Cardiopulmonary Status
First Claim
1. A method, comprising:
- sensing a first set of one or more physiological parameters using one or more first sensors of a first medical unit configured to operate outside a patient'"'"'s body;
sensing a second set of one or more physiological parameters using one or more second sensors of a second medical unit configured for operation inside the patient'"'"'s body;
identifying, based on one or both of the first set of physiological parameters and the second set of physiological parameters, a cardiopulmonary disorder affecting a patient as a breathing rhythm disorder or identifying, based on one or both of the first set of physiological parameters and the second set of physiological parameters, the cardiopulmonary disorder affecting the patient as a non-rhythm breathing disorder, wherein identifying the cardiopulmonary disorder as a non-rhythm breathing disorder comprises discriminating between pulmonary edema and at least one other pulmonary vascular disorder; and
controlling a therapy delivered to the patient based on the identified cardiopulmonary disorder, wherein at least one of identifying and controlling are performed using circuitry.

Abstract
Methods and systems provide an approach to therapy control based on assessment of a patient'"'"'s cardiopulmonary status. Conditions sensed via sensors of an external respiratory therapy device are used to assess a patient'"'"'s cardiopulmonary status. The respiratory therapy device sensors may be utilized alone or in combination with other sensors to determine cardiopulmonary status of a patient. Therapy delivered to the patient is controlled based on the cardiopulmonary status assessment. For example, therapy delivered to the patient may be initiated, terminated, and/or modified based on the assessed cardiopulmonary status of the patient. Cardiopulmonary status assessment, therapy control, or both, are performed by an implantable device.

13. A medical system, comprising:
-
one or more first sensors of a first medical unit, the first medical unit configured for operation outside a patient'"'"'s body, the one or more first sensors configured to sense a first set of one or more physiological parameters; one or more second sensors of a second medical unit configured for operation inside a patient'"'"'s body, the one or more second sensors configured to sense a second set of one or more physiological parameters; a cardiopulmonary status processor configured to identify, based on one or both of the first set of physiological parameters and the second set of physiological parameters, a cardiopulmonary disorder affecting a patient as a breathing rhythm disorder, identify, based on one or both of the first set of physiological parameters and the second set of physiological parameters, a cardiopulmonary disorder affecting the patient as a non-rhythm breathing disorder, wherein the cardiopulmonary status processor is configured to discriminate between pulmonary edema and at least one other pulmonary vascular disorder to identify the non-rhythm breathing disorder; and a therapy controller configured to control a therapy delivered to the patient based on the identified cardiopulmonary disorder. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
