ABSTRACT:
A portable respiration apparatus is dimensioned to convey a flow of gas, with an upper limit on pressure, from an inlet to an outlet connected to a patient. The inlet of the portable respiration apparatus can be connected to a stationary gas unit when a higher pressure is desired. The stationary gas unit can generate a gas pressure that is applied to the inlet of the portable respiration apparatus, so that a higher gas pressure can be generated and delivered to the patient. Alternatively, the stationary gas unit can be dimensioned so that it is itself capable of generating the desired gas pressure to be supplied to the patient, so there is no additional increase in gas pressure in the portable respiration apparatus.
