ABSTRACT:
A method and apparatus for intratracheal ventilation (ITV) and intratracheal pulmonary ventilation (ITPV) in which a catheter positioned in a patient's trachea at the carina supplies a constant supply of fresh oxygen containing gas to flush anatomical dead space. By positioning the catheter in the patient's trachea, the dead space of the trachea is bypassed and the trachea is only utilized for expiration. The catheter includes a catheter tip which directs the constant supply of fresh oxygen containing gas in a manner so as to create sub-atmospheric pressures near the carina and thus allows control of intratracheal airway pressures during the entire respiratory cycle and prevents overinflation of the lungs.
