Abstract
The embodied invention is a new inspiration/expiration ventilator flow design, with a constant inspiration flow and intermittent-concurrent expiratory flow based on lung pressure setpoints. This mode is possible by using a new dual lumen tube inserted into a patient Trachea. Additionally, the control provides support for patient initiated breathing which is initiated by a lung pressure drop. This control provides continuous and gentle recruitment of lung alveoli.
