Abstract
A ventilator system has an inspiratory line, an inspiratory pressure meter arranged to sense pressure in the inspiratory line, and expiratory line, an expiratory pressure meter arranged to sense pressure in the expiratory line, and a connector device for connecting a patient to the ventilator system. The connector device includes a first gas line connected to the inspiratory line, and a second gas line connected to the expiratory line so that gas will only be able to flow in one direction through the lines. Pressure in the lungs can accordingly be directly measured by the expiratory pressure meter during inspiration and by the inspiratory pressure meter during expiration.
