Abstract
Improved methods and devices are described for sensing the respiration pattern of a patient and controlling ventilator functions, particularly for use in an open ventilation system. A ventilation and breath sensing apparatus may include a ventilation gas delivery circuit and a ventilation tube coupled to the ventilation gas delivery circuit. A plurality of pressure sensing elements may be separated by a distance and may produce independent signals. The signals may be used to detect pressure differentials between the plurality of pressure sensing elements. Sensing ports may be located in an airway, and connected to transducers that are valved to optimize sensitivity and overpressure protection. Airway pressure and flow can both be obtained and used to optimize ventilator synchronization and therapy.
