1. A device suitable for aiding, forcing or initiating the breathing of living beings, said device comprising a venturi device within a first conduit by which air can be entrained through said first conduit from behind said venturi device, a second conduit of predetermined length provided in front of said venturi device, said second conduit being of a significantly greater diameter than a throat of the venturi device so as not to adversely affect the entrainment of air thereby, said second conduit being coupled to a mask having first and second apertures through which gas can exhaust, said first aperture being disposed in sealing relationship with an air intake passage of a living being, and further comprising a pressure actuable valve having open and closed conditions, said pressure actuable valve being positioned in the first conduit upstream of said venturi with entrained air necessarily passing through said pressure actuable valve when open, said pressure actuable valve being automatically closed when the second aperture of the mask is blocked thus immediately increasing the pressure in the first and second conduit and constraining a volume of gas within the second conduit to be delivered under pressure to the living being through the first aperture of said mask.
