Intermittent vacuum therapy

from Wikipedia, the free encyclopedia

The intermittent vacuum therapy (IVT) is a method which can be carried out at certain venous and arterial issues as well as in the rehabilitation (after sports and vascular disease). The use of pressure and negative pressure should make it possible to control the venous return flow, to stimulate the lymph flow and to improve the circulation in the periphery and muscles.

technology

The devices for applying IVT consist of a cylindrical space in which the lower body of the patient lying down is enclosed up to the base of the ribs and pressurized. The legs are completely enclosed by the tube. In the area of ​​the waist, the interior is sealed with the help of a lens. A vacuum pump is used to intermittently generate alternating negative and normal pressure (−20 to −70 mbar) in the room. The devices are considered medical products (EC Directive 93/42 / EEC Class IIa. CE 0123).

Mode of action

By creating negative pressure, blood circulation in the lower extremities and abdomen is stimulated, i. i.e., arterial perfusion is stimulated. "This blood movement leads to a lowering of the blood pressure in the central vein, the heartbeat volume, the cardiac output and ultimately to a lowering of the arterial blood pressure, which the compensation mechanisms must counteract." In response to these changes, the pulse and peripheral vascular resistance increase. In addition, the sympathetic response to the heart is activated. The blood volume adapts to changes in pressure in the lower body. The changing conditions - normal and negative pressure - stimulate and increase the flow of oxygenated blood in the legs and lower extremities. In the normal pressure phase, the return of the venous blood and the lymph into the large vessels is promoted. The intermittent vacuum treatment has a "strong physiological effect" on the "removal of loads that are subject to the lymphatic system"; H. it finds a lymphatic drainage instead. The associated pH increase often leads to a strengthening of the connective tissue, which is influenced by the increase in collagen synthesis, and to faster fat breakdown.

The treatment method was developed on the basis of NASA's LBNPD method ( lower body negative pressure device , device for the negative pressure in the lower body). In 1999 the development of the intermittent version of the LBNPD began as a neurolab research project at the Institute for Space Medicine of the German Aerospace Center (DLR).

treatment

The average duration of treatment is 4 to> 10 applications (30–45 minutes each), depending on the indication. Numerous indications for intermittent vacuum therapy are listed, but in many cases there is still a need for research as the results are not always clear. For example: weak connective tissue, acidosis, cellulite and spider veins, injuries (e.g. bruises and sports injuries), vascular diseases, edema and ulcers . Other indications that have been treated with IVT in the Netherlands since the beginning of 2013 include: a. the RSI (repetitive strain injury syndrome) , CTS (carpal tunnel syndrome) , CRPS (complex regional pain syndrome) , epicondylitis and Raynaud's syndrome .

Contraindicators

Negative effects have not yet been found, but the procedure should not be used in acute diseases such as phlebothrombosis ( deep vein thrombosis ), thrombophlebitis (inflammation of the veins ), infections or pregnancy .
