A ventilation catheter and airway management system is described to create conditions that tend to clear secretions during the normal conduct of ventilation by having an exclusive outflow channel and/or to use a programed cuff leak combined with PEEP to protect the airway. The secretion clearing endotracheal tube may include separate inflow and outflow paths as part of a double lumen, to facilitate breathing when placed in a patient. The double lumen portion intersecting to form a single lumen for protrusion into the intratracheal region allowing the new inspiratory fluid from the airway management system to flow into a patient and the used inspiratory fluid from the patient to flow back to the airway management system. A pharyngeal suction component removes fluid from the intratracheal region via periodic suctioning.
