Fluid Overload (Hypervolemia)

Category: science

A complication occurring when intravenous fluid volumes exceed the pumping capacity of the animal’s cardiovascular system.

Hypervolemia causes excess fluid to leak into tissue spaces. It leads to peripheral edema or fatal pulmonary edema (fluid in the lungs). Animals with underlying heart or kidney disease require precise micro-infusion pumps to keep fluid rates strictly within safe operational boundaries.

Common Examples

• The technician checked the feline patient's respiratory rate frequently to monitor for early indicators of clinical fluid overload.
• Early signs of fluid overload include an accelerated resting respiratory rate, clear nasal discharge, and harsh crackles during chest auscultation.
