[Possibilities of the method of dilution of electro-impedance indicators in the assessment of volume dynamics of extravascular lung fluid in intensive care and resuscitation units].

The possibility of using impedance plethysmography to assess changes in the volume of the extravascular lung fluid in intensive therapy and resuscitation patients is discussed. Changes in the volume of the fluid during extracorporeal detoxication are analysed. A correlation was found between these changes and lung distensibility (r = -0.7). A significant diminution of the fluid volume was observed in response to therapeutic doses of Lasix and Nitroglycerin. Data are cited on the increasing (85 percent) volumes of the fluid in preclinical pulmonary edema in patients with left ventricular insufficiency.
