APPARATUS FOR MEASURING EXTRAVASCULAR LUNG WATER.

摘要

apparatus and method for the measurement of extravascular lung water in a patient using a thermal indicator.including means (16) for the distribution of the injection of the thermal indicator in the blood stream of the patient in a proximal position, or in the right heart (10).means (26) for identifying a first time - temperature curve of concentration of blood stream in a position in the pulmonary artery, means (104) are sensitive.in response to the first temperature - time curve of concentration found in the pulmonary artery.in order to calculate a time for the first time curve of absolute temperature concentration.means (28) for identifying a second time - temperature curve, concentration in the blood stream in a position in an artery of the general circulation.means (104) for calculating the flow of blood through the heart and lungs.and means (104) for calculating a measure of lung extravascular water in accordance with the difference between the product of blood flow after the first time the process underthe product of the blood flow and then to characterization.
