A torsion beam for a suspension in a vehicle and a body member defining an outer shape is made of carbon fiber reinforcing plastic that is an advanced composite, so the weight can be reduced, and thus the torsion beam can be used for environment-friendly vehicles. An additional amount of oxygen is administered to the lungs via a jet gas current at the end of an inhalation procedure. Additionally, the present invention can be implemented with minimal changes to an existing RLP3E implementation.
