ABSTRACT:
This volumetric respiration equipment is of the type comprising means for spraying air, oxygen and/or anesthetic products into the patient's lungs and to produce alternatively a negative pressure therein, said means incorporating a source of fluids under pressure as well as a circuit for said fluids, and being associated with respiratory valves and also with means for operating the equipment with the maximum reliability. Said source of fluids under pressure is such that it can deliver the fluids into the circuit under a pressure relatively low yet higher than the pressure that the patient's lungs can normally withstand, the proportioning of the inhaling to breathing-out cycle periods being obtained without resorting to any electric circuit, but only by using the motive power derived from the pressure fluid supply.
