Carbonated water baths represent a method used for the prevention and treatment of cardiovascular diseases in some spa resorts in Romania. Carbonated mineral waters are the result of the filtration of depth waters through volcanic soils that contain carbon dioxide. The most important effect is the direct effect of carbon dioxide, which is absorbed through the skin, with an absorption coefficient of 30-35 ml/min/sqm body surface area. An excitation of vascular receptors and a dilation of dermal papillae, responsible for skin erythema, occur. The effects of the carbonated water bath on the cardiovascular system are the following: decrease of peripheral resistance by the direct action of carbon dioxide on arterioles and arteriovenous anastomoses; increase of both systolic and diastolic cardiac output, not by central mechanism as in the case of hot baths, but initially, by passive peripheral vasodilation, without increased venous return; subsequently, by accumulation in the cutaneous venous system, venous return towards the right heart will be increased, with a higher diastolic filling and a higher stroke volume. Carbonated water baths increase arteriolar blood flow in the skin, the vasodilator effect being directly proportional to the carbon dioxide concentration in the mineral bath. The effect of external carbonated water treatment is based on mechanical and thermal action, as well as on the chemical properties of carbon dioxide, its influence being either local or postabsorptive. Carbonated water baths are a therapeutic method that is also used in the treatment facilities of the Baile Tusnad spa resort, under the supervision of qualified medical experts, in a pleasant environment close to nature.
