Abstract: A method and a device for switching to the inspiration or expiration phase during CPAP therapy are disclosed. By means of a first high threshold value and a second low threshold value non-specific influences on the first derivative of the gas flow curve are suppressed in the corresponding breathing phase and the transition to the corresponding following gas phase is determined with high sensitivity. The invention further relates to methods for recognizing and suppressing the influence of the pulse or for switching to the inspiration phase in case of shallow breathing. The advantages of the invention are greater switching accuracy and improved safety for the patient.
