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. An apparatus for sensing respiration and synchronizing a ventilator to the respiration of a patient is described. The apparatus may include a plurality of thermal breath sensors. At least one of the plurality of thermal breath sensors may be a heated thermal breath sensor.
