Method and device for stabilising disordered breathing
First Claim
1. A device for improving the stability of a ventilation pattern of a patient comprisingat least one sensor for sensing a parameter which reflects a level of lung gas in a patient and for producing an output signal indicative of said parameter, anda processor adapted to receive and process the sensor output signal to assess the lung gas level, the processor being in communication with means for increasing the lung gas level of the patient, and being configured to produce a control signal for instructing said means in response to a decreasing level or a predicted decreasing level of lung gas, so as to retard a decrease in said lung gas level.

Abstract
A device and method for improving the stability of a ventilation pattern of a patient (1) uses a sensor (4) for sensing a parameter which reflects a level of lung gas in a patient, such as oxygen or carbon dioxide. The output signal of the sensor is received by a processor (3) which assesses the level of lung gas of the patient and activates means (18,20) for increasing the lung gas level of the patient beyond what it would otherwise have been without treatment in response to a decreasing level or a predicted decreasing level of the lung gas. Thus the device can be used to retard a decrease in said lung gas level, thereby reducing oscillations in the respiration.
