<p>A method and apparatus for intratracheal ventilation (ITV) and intratracheal pulmonary ventilation (ITPV) in which a catheter (1) positioned in a patient's trachea at the carina (6) supplies a constant supply of fresh oxygen containing gas (13, 14, 15) to flush anatomical dead space. By positioning the catheter (1) in the patient's trachea, the dead space of the trachea is bypassed and the trachea is only utilized for expiration. By providing a timed expiratory valve (9) in the ITPV mode, lower pressures and fresh oxygen flow rates may be utilized with respiratory rates from 10 to 120/min. or higher.</p> |
