Abstract
A system selectively delivers either breath-synchronized, flow-targeted ventilation (BSFTV) or closed-system positive pressure ventilation (CSPPV) to augment respiration of a patient with a standard tracheal tube. A removable adaptor has a cap that can be removably attached to the proximal connector of the tracheal tube in BSFTV mode, and an inner cannula that extends within the tracheal tube to effectively divide it into two lumens. The adaptor includes a ventilator connector for removably engaging a ventilator hose to deliver air/oxygen through the adaptor and one lumen of the tracheal tube with a flow rate varying over each respiratory cycle in a predetermined waveform synchronized with the patient's respiratory cycle to augment the patient's spontaneous respiration. The adaptor also includes a port allowing the spontaneously-breathing patient to freely inhale and exhale in open exchange with the atmosphere through the other lumen.
