The present invention relates generally to the field of ventilators, and, more specifically, to a ventilator system that addresses respiratory distress due to the onset of an epidemic or pandemic disease state. In particular, the present invention is a ventilator system that can be manufactured quickly with minimal skill requirements and employed rapidly in response to epidemic respiratory disease conditions. In one embodiment, the present invention is directed toward a ventilator having a gas input, an inhalation conduit connected to the gas input, a patient flow control valve, operably connected to the gas input via the inhalation conduit, a patient interface, separated from the inhalation conduit by the flow control valve, and a gas shut-off mechanism that senses a pressure state in the inhalation conduit.본 발명은 일반적으로 인공 호흡기 분야, 더욱 상세하게는, 전염병 또는 광역 전염병 상태의 발발에 기인하여 호흡 곤란을 처리하는 인공 호흡기 시스템에 관련한다. 특히, 본 발명은 최소한의 기능 요건을 가지고 빠르게 제조될 수 있으며, 전염병의 호흡 질병 상황에 재빠르게 응답하여 사용될 수 있는 인공 호흡기 시스템이다.
