Title (EN) WEIGHT MEASUREMENT OF BLOOD VOLUME IN SOFT-SHELL VENOUS RESERVOIRS
(FR) MESURE PONDERALE DU VOLUME SANGUIN DANS UN RECIPIENT VEINEUX A PAROI SOUPLE
Abstract:
(EN) An accurate real-time volume measurement of the blood content of a soft-shell venous reservoir is obtained by computing the volume from the weight of the blood in the reservoir modified by the hematocrit of the blood.
(FR) On peut mesurer avec précision et en temps réel le volume sanguin contenu dans un réservoir veineux à paroi souple en calculant ce volume à partir du poids du sang contenu dans ledit réservoir, puis en le corrigeant en fonction de l'hématocrite du sang.
