<Li> If fluid loss is greater than fluid gain (for example if the patient vomits and has diarrhea), the patient is said to be in negative fluid balance . In this case, fluid is often given intravenously to compensate for the loss . </Li> <Li> On the other hand, a positive fluid balance (where fluid gain is greater than fluid loss) might suggest a problem with either the renal or cardiovascular system . </Li> <P> If blood pressure is low (hypotension), the filtration rate in the kidneys will lessen, causing less fluid reabsorption and thus less urine output . </P> <P> An accurate measure of fluid balance is therefore an important diagnostic tool, and allows for prompt intervention to correct the imbalance . </P>
