Plethysmograph, Air Displacement For Body Composition Analysis
- Page Type
- Product Code
- Definition
- To measure the total body volume and weight for calculating the estimated body composition (total body fat and total body lean mass).
- Physical State
- An air-tight, dual compartment fiberglass and plexiglas chamber that the subject enters
- Technical Method
- Uses Boyle's law in conjunction with the two precisely-sized compartments to determine the volume occupied by the subject's body. Average total body density is calculated from the weight and volume determined by the device. Empirical equations, as a function of density of known tissue types, are then used to estimate body composition parameters.

CFR § 870.2770 Impedance plethysmograph
§ 870.2770 Impedance plethysmograph.
(a) Identification. An impedance plethysmograph is a device used to estimate peripheral blood flow by measuring electrical impedance changes in a region of the body such as the arms and legs.
(b) Classification. Class II (special controls). The device, when it is a body composition analyzer which is not intended to diagnose or treat any medical condition, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.
