ABSTRACT:
An insufflation system that includes a first tube that inserts into a patient's airway for providing a primary flow of breathing gas to such a patient. At least one insufflation catheter is provided in or within the first tube for delivering a flow of insufflation gas to the patient. In one embodiment, the flow of insufflation gas is delivered in a first direction generally toward the patient's lungs and in a second direction generally opposite the first direction so that the flow in the second direction creates a negative stagnation pressure that substantially cancels out the positive stagnation pressure generated by flow in the first direction. In second embodiment, an exhaust vent is provided in the first tube for exhausting a flow of gas from the first tube at a rate that is equivalent to the rate at which the flow of insufflation gas is being delivered to the patient's airway, thereby preventing over-inflation of the patient's respiratory system. A third embodiment of the present invention involves a combination of the two embodiments discussed above.
