Air-displacement plethysmography is a densitometry technique used to determine body composition with air displacement (instead of water displacement, as used with hydrostatic weighing) to determine body volume. The equipment consists of a closed airtight chamber ... The volume of air in the chamber when the chamber is empty is known. When a person enters the airtight chamber, he displaces his own volume in air. The volume of air remaining in the chamber is determined (with a correction for thoracic air volume). The person's body volume is the difference between the volume of air in the empty chamber minus the volume of air in the chamber when the person is in the chamber.

[Air] plethysmoghaphy uses a pneumatic cuff wrapped around an extremity or digit. By standardizing the injected volume of air and therefore the pressure inside the cuff, momentary volume changes are detected by a transducer and displayed as waveforms also called "pulse volume recordings".

Trois examens sont essentiels pour évaluer l'insuffisance veineuse chronique : la pléthysmographie à air qui quantifie le reflux en volume et en vitesse, le VFI (index de remplissage veineux) exprime le débit de remplissage veineux lors du passage à la position verticale et le VFT90 (temps de remplissage veineux) exprime la durée mise par le reflux pour remplir 90 % du volume fonctionnel lors du passage à la position verticale.
