US 9,808,590 B2 · Method and device for carrying out a signal-processing viewing of a measurement signal that is correlated to the respiratory activity of an individual

Abstract

The invention relates to a method and device for carrying out a signal-processing viewing of a measurement signal that is correlated with the respiratory activity of an individual, for example, of a measurement signal that is correlated with the respiratory gas. The aim of the invention is to provide solutions with which an improved electronic analysis of the signals that are representative with regard to respiratory activity can be achieved. To this end, the invention provides that viewing results are obtained within the scope of a signal-processing viewing of said measurement signal and make a differentiation between obstructive and central respiratory disorders possible. The viewing results are determined, in particular, while taking into account changes of selected breathing characteristics such as, for example, the change in the ratio of inhalation time to exhalation time.

Dependent claims

A method of controlling pressure provided to a patient by a pressure regulating device, the method comprising:

providing a supply of respiratory gas at a first pressure level above ambient pressure level;
measuring a signal indicative of respiratory activity;
determining, using a signal processing device, an inspiration phase and an expiration phase of each breath from the signal;
detecting, using the signal processing device, an inspiration time and an expiration time of each breath for successive breaths;
determining, using the signal processing device, a ratio of the inspiration time to the expiration time for each said breath;
detecting, using the signal processing device, a variation in the ratio;
determining, using the signal processing device, presence of obstruction of the upper respiratory tract based on the in the ratio;
and adjusting the first pressure level based on the determined presence of obstruction.
