Plasma expanders

Plasma expanders are medical fluids used to increase blood volume when someone has lost a significant amount of blood or their blood pressure drops dangerously low. They work by drawing water into the bloodstream, helping maintain circulation and blood pressure until more permanent solutions, like blood transfusions, can be provided. Common types include saline solutions and synthetic fluids that mimic blood plasma's volume-expanding properties. They don’t carry oxygen like blood cells but are vital in emergency care to stabilize patients and ensure organs receive enough blood flow.
