Therapy control based on cardiopulmonary status
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.
