A bidirectional flow-controllable artificial respirator, according to one embodiment, comprises: a chamber for storing air; a tube connected to the chamber and having air flowing therein; a mask connected to the tube and mounted on a face or mouth; and a flow control valve unit provided in the tube and controlling the air flow between the chamber or an air supply source, and the mask. The flow control valve unit comprises: a first valve allowing an air supply path from the air supply source toward the mask; and a second valve allowing an air discharge path from the mask toward the outside of the respirator, wherein the first valve and the second valve are alternately opened and closed during artificial respiration, the first valve is blocked during chest compressions so that negative pressure in a subject receiving air is maintained for a long period, and the first valve and the second valve may be selectively opened and closed so as to allow air to be supplied according to a preset air supplying period.

A ventilator adaptor for switching between ventilator devices while maintaining respiratory support to a patient is described. The ventilator adaptor has a first movable element with a first inlet and a second inlet, and a second movable element movably attached to the first movable element and with an outlet. The outlet has an inner diameter of 14.5-15.5 mm, preferably 15 mm, and the first inlet and the second inlet have an outer diameter of 14.5-15.5 mm, preferably 15 mm. The outlet is in fluid communication with the first inlet in a first position or with the second inlet in a second position by moving the second movable element relative to the first movable element thereby aligning the outlet with the first inlet or the second inlet. The outlet may be attached to an endotracheal tube in order to form a ventilation assembly.

The invention relates to a gas delivery apparatus (1) having an internal gas passage (100), a deformable reservoir (27), a valve device (22), and a control unit (50) with microprocessor (51) controlling the valve device (22) in order to set or adjust the flow rate of gas passing through said valve device (22). A flow rate determination device (60) makes it possible to perform measurements of pressure or flow rate in the internal gas passage (100) and to transmit these measurements to the control unit (50). A pressure sensor (55) performs gas pressure measurements (P.sub.55) on the therapeutic gas feeding the deformable reservoir (27) and supplies them to the control unit (50). A breathing mask (10) is in fluidic communication with the internal gas passage (100) in order to be fed with therapeutic gas coming from the deformable reservoir (27).
