ABSTRACT:
A soft-sided air displacement volumometer includes a soft-sided bag, an air injector, a pressure transducer, and a recording device. The soft-sided volumometer is used to measure the total body volume of a person or the volume of one limb of a person. After the person enters the soft-sided bag, the bag is sealed and pressurized to a predetermined level using the air injector. The pressure inside the soft-sided bag is continuously monitored using the pressure transducer and recording device while the volume of the soft-side bag is incrementally reduced. The elasticity of the soft-sided bag is eliminated from the volume calculations by operating the soft-sided air displacement volumometer over a relatively small range of volumes and pressures in which the elasticity is substantially constant. The volume of the person inside the soft-sided bag is calculated as the volume of the empty bag (i.e. without a person) minus the initial volume of the bag with the person pressurized to an initial pressure level.
