1. A system for augmentation of spontaneous breathing of a patient having difficulty in fully self-breathing, said system assisting the relaxing of the respiratory muscles of the patient and in the removal of carbon dioxide from the lungs of the patient, said system comprising:

  • a transtracheal catheter inserted into the trachea of the patient, said transtracheal catheter having an outer diameter substantially smaller than the cross-sectional area of the trachea so not to obstruct the spontaneous breathing of the patient, said transtracheal catheter having a first end extending into the trachea to a point in the trachea just above the carina and a second end extending outwardly from the patient; and

    supply means connected to said second end of said transtracheal catheter for providing an oxygen/air mixture through said transtracheal catheter at a continuous high flow rate to deliver said oxygen/air mixture evenly into the lungs of the patient to augment the spontaneous breathing of the patient, said high continuous flow of oxygen/air mixture assisting the removal of carbon dioxide from the lungs through the trachea of the patient into the ambient atmosphere so as to relax the respiratory muscles of the patient.
