Abstract:
1. A tracheal gas insufflation system comprising: a patient circuit adapted to couple a ventilator to an airway of a patient; an insufflation catheter having a proximal end portion located generally outside a patient and a distal end portion adapted to be located in an airway of a patient for providing a flow of insufflation gas to such a patient; a source of insufflation gas; and a flow control system coupled between the patient circuit, the insufflation catheter, and the source of insufflation gas so as to control a flow of gas between the patient circuit, the insufflation catheter, and the source of insufflation gas, wherein the flow control system includes a first selectively actuatable valve connected between the source of insufflation gas, the insufflation catheter, and the patient circuit, wherein the first valve is adapted to be arranged to: a) communicate the insufflation catheter with the source of insufflation gas and disconnect the patient circuit from the source of insufflation gas and the insufflation catheter in a first configuration, b) communicate the insufflation catheter with the patient circuit and disconnect the source of insufflation gas from the insufflation catheter and the patient circuit in a second configuration.
