Blood replacement therapy involves intravenous fluid administration,which inherently increases the risk for overhydration.The fact that the fluid consists of packed red blood cells greatly increases the risk,because this fluid increases the colloidal oncotic pressure of the blood,causing fluid to move from interstitial and intracellular spaces into the plasma volume.An older adult may not have sufficient cardiac or renal reserve to manage this extra fluid.
