ABSTRACT:
The present invention provides a system for augmenting ventilation and removing carbon dioxide of a spontaneous-breathing patient and a method of use thereof. The system further allows relaxation of the breathing process thus reducing fatigue of the patient. The system involves providing a high continuous flow of a humidified oxygen/air mixture at a predetermined oxygen content and at a constant flow rate through a transtracheal catheter into the lungs of the patient. The system typically provides an oxygen/air mixture of at least 21 percent oxygen, at a humidity between 80 to 100 percent, and a temperature of 35 to 38 C. The mixture is delivered through the transtracheal catheter at a flow rate of 8 to 20 liters per minute at a back pressure of 2 to 25 psi.
