Method and apparatus for providing ventilatory assistance

摘要: The apparatus provides for the determination of instantaneous phase in respiratory cycle, subject's average respiration rate and provision ventilatory assistance. A microprocessor ( 16 ) receives an airflow signal from a pressure transducer 18 coupled to port 17 at mask 11 ). controls servo 19 ), that turn fan motor 20 thus air delivered by blower 10 is (ii) conduit 12 invention seeks address following goals: while subject awake making substantial efforts assistance should be closely matched with efforts; machine automatically adjust degree maintain least specified minimum ventilation without relying on integrity chemoreflexes; it continue work correctly presence large leaks.
