Abstract
The invention provides a system for improved respiratory actuation of a patient, being connected to a mechanical ventilator or breathing apparatus, wherein the system is based on controlling the expiration or expiratory flow during the expiratory phase. The system for improved respiratory actuation being preferably balanced by means of inducing a constant expiratory flow being equal to a constant inspiratory flow.
Claims7
A system for providing a balanced respiratory actuation of a patient (110), being connected to a respiratory apparatus (100) for breathing, the respiratory actuation comprising an inspiratory and an expiratory phase (20, 30) during which respectively inspiration and expiration of the patient (110) takes place, wherein the system comprises a controller for executing a control algorithm (i) monitoring the inspiratory airway pressure and herewith defining a trajectory for the inspiratory phase, and (ii) based thereon, dynamically adjusting the flow of pressurized air in the expiratory line, herewith controlling the (lung or airway) pressure towards a predetermined trajectory, wherein said predetermined trajectory being based on the monitored inspiratory airway pressure and resembling in shape the trajectory of the inspiratory phase.
