Process for switching the inspiration or expiration phase during CPAP therapy

摘要

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.
