Intermittent gas-insufflation apparatus

摘要: An intermittent gas-insufflation apparatus (10) insufflates a quantity of the gaseous fluid into an entrance (16) respiratory system breathing patient (14) during exhalation interval immediate cycle and subsequent inhalation (26) successive (28). The includes valve assembly (30), sensor (32) controller (34). (30) actuates between closed state to prevent from flowing source (12) opened establish flow (14). detects changes in pressure throughout (24) generates signals characteristics thereof. (34) receives processes either (18) (24), (22) or both is responsive within actuate so that flows Methods are also described for various exemplary embodiments present invention maintenance blood-oxygen concentration receiving oxygen supplemental delivery system.
