First Claim
Patent Images
1. A method for modifying the breathing of a patient, comprising the following steps:
- monitoring an instantaneous pulmonary ventilation of a patient;
identifying limit cycle behavior of the instantaneous pulmonary ventilation, the limit cycle behavior corresponding to a limit cycle having phases; and
applying a transient intervention to the patient according to a phase of the limit cycle, the transient intervention having an effect on a breathing state of the patient.

Abstract
A method for modifying the breathing of a patient while the patient is experiencing sleep apnea, for example Cheyne Stokes breathing. An instantaneous pulmonary ventilation of a patient is monitored. Limit cycle behavior of the instantaneous pulmonary ventilation is identified. A transient intervention is applied to the patient during a phase of a limit cycle of the instantaneous pulmonary ventilation. The transient intervention has an effect on a breathing state of the patient.

17. An apparatus for treating a breathing disorder, comprising:
-
a sensor adapted to detect a characteristic of respiration; a transient intervention system; and a controller adapted to control operation of the transient intervention system responsive to signals from the sensor so as to cause the transient intervention system to apply a transient intervention to a patient. - View Dependent Claims (18, 19, 20)
