What is positive fluid balance or hypervolemia?

Hypervolemia:

1. When a patient's fluid inflow exceeds his or her output, he or she is said to have a positive fluid balance.
2. Fluid overload, also known as hypervolemia, is a medical disorder characterized by an excess of fluid.
3. Hypervolaemia causes an accumulation of fluid in the circulatory system, which can exhaust the heart and cause pulmonary edema, kidney damage, congestive heart failure, fluid resuscitation, and other factors that can all contribute to this disease.
