Medical ventilator i.e. anesthesia ventilator, for e.g. lung of patient, has bypass cardiopulmonary circuit comprising supply branch for supplying gas to bypass cardiopulmonary membrane system, and gas source delivering gas into branch
The ventilator has a gas circuit i.e. ventilation circuit (1), comprising an inspiratory branch (11) for administering anesthetic gas to a patient and an expiratory branch (12) for recuperating the gas expirated by the patient. A gas source (3) e.g. fan, delivers the gas or gaseous mixture into the branch (11). Bypass cardiopulmonary (BCP) circuit (2) includes a supply branch (21) for supplying gas to a BCP membrane system (30) and a gas recuperating branch (22) for recuperating part of non-consumed gas in the system. The gas source delivers gas or gaseous mixture into the supply branch.
