Embodiment Construction

[0018] In the claims, the word "comprising" is used in its inclusive sense and does not exclude other presented elements. The indefinite article "a" or "an" preceding a claim does not exclude the presence of more than one feature. Each of the individual features described here can be used in one or more embodiments, but are not limited only to what is presented here, but rather to the interpretation of the defined claims based on all embodiments. "Transient lung ventilation" in the context of the specification refers to the ratio of tidal volume divided by the respiratory cycle of human respiration.

[0019] figure 1 and figure 2 Indicates the method used to adjust the patient's breathing. In step 10, the patient's transient lung ventilation is monitored. As shown in step 12, the limit cycle behavior is detected, and at that time, as shown in step 13, transient lung ventilation is in a limit cycle phase, and then in step 14 to the patient affected alveolar ventilation of ...

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.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application No. 60 / 952,084, filed July 26, 2007, which is incorporated by reference in its entirety. technical field [0003] The present invention relates to a method and apparatus for providing a transient intervention to stabilize a patient's breathing pattern, and, more particularly, to a method comprising identifying a limit cycle behavior of a patient and providing said intervention according to a phase of said limit cycle and instrument. Background technique [0004] Central sleep apnea is a type of sleep-disordered breathing characterized by a malfunction of the sleeping brain to produce regular, rhythmic bursts of nervous system activity. The resulting cessation of rhythmic breathing, referred to as apnea, manifests itself as a disturbance of the respiratory control system responsible for regulating the rate and depth of respiration; ie, a disturbance of global lung ventil...
