摘要: A process is disclosed for switching the inspiration or expiration phase during CPAP therapy. first high threshold value and a second low enable non-specific influences on derivative of gas flow curve to be suppressed in corresponding breathing transition next determined with sensitivity. The advantages invention are higher accuracy safety patient.
