["Determination of venous hemodynamics". Contribution of air plethysmography].

Plethysmographic techniques based on the variation of a parameter linked to venous stasis, have permitted an approach to venous hemodynamics. The use of a new technique of air-plethysmography, which cold be quantified in volume variation, and permitting to study the progression of the venous stasis from a static as well as a dynamic standpoint, enable us to better assess the overall venous function. The first results obtained in healthy patients, are presented and the advantages of this new technique are discussed.
