The respirator system controls operation of an exhale gas pressure control valve and an delivery gas flow control valve interposed in tubes leading to the patient's airway. Each control valve is operated by a Venturi flow pilot valve having a variable exhaust flow which is a function of an electromagnetic linear actuator. Operation of the electromagnetic actuator is accurately controlled by computer hardware and software, which can operate the pilot valves to meet a wide range of ventilation modes for patients of any size or physical condition. |
