Change of Blood Pressure Due to Volume Changes

Abstract

In this work dextrose normal saline (DNS) infusion (500ml) with 8.3ml/sec was add to blood, it was found that the blood pressure decreases when increasing the infusion amount. This may be due to the fact that increasing infusion amount decreases blood density which in turn decrease blood pressure. This effect can be easily explained on the basis of continuity equation and Bernoulli’s equation
