The present invention provides an automated respiration method involving positive airway pressure. The method comprises a step for measuring the respiratory gas flow and comparing it with a threshold value. A further step is provided for assessing any obstructive respiratory disturbance. An evaluation step evaluates the measurement values and determines whether it is a case of normal breathing, obstructive respiratory disturbance, non-obstructive respiratory disturbance or snoring. Depending on the results provided by the evaluation step, the positive airway pressure is either maintained or modified. It is the advantage of the invention that the respiratory gas flow as well as the airway obstruction are continuously measured, thereby enabling the positive air pressure to be adjusted to different individual states of the patient.

Automatic respiration under positive airway pressure

A method of changing to the inhalation or exhalation phase in the CPAP therapy is provided. By means of a first, high threshold value and a second, low threshold value, nonspecific influences on the first derivative of the gas flow curve are suppressed in the respective breathing phase and the transition to the respective next gas phase is determined with high sensitivity. The advantages of the invention are in a higher precision of the changing operation and in a greater safety for the patient.
