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