ABSTRACT:
A tracheal tube ventilation apparatus to more effectively remove expired gases. In one preferred embodiment, one or more leak holes are created in the side walls of an endotracheal tube so that expired gases can leak out of the endotracheal tube above the larynx, such as into the back of the mouth (i.e., oropharynx). Each leak hole might advantageously have a diameter between 0.5 and 4.0 mm. In another preferred embodiment, a tube is attached to a proportionately larger leak hole (e.g., up to 8.0 mm) so that the expired gases can be directed away from the leak hole to a specific location, such as directed out of the mouth. In the case of mechanically controlled ventilation, a positive end expiratory pressure can be applied to this tube to mechanically assist with the process of exhaling. In each of these embodiments, it is preferred, but not required, that the endotracheal tube be an ultra-thin walled, two stage tube so as to further assist in the reduction of resistance to the flow of oxygen/air.
