Because the blood is actively pumped into the donor’s veins, there is the theoretical possibility that air could be pumped into the donor if air enters the system. Some of the early models of apheresis instruments contained bubble chambers connected to a device that stopped the pumps if the chamber became filled with air. Air emboli have occurred but without reports of serious consequences. Contemporary instruments do not contain safety devices to prevent air embolus, and so this complication remains a concern. Staff members must be aware of this possibility and ensure that containers and tubing sets do not develop leaks that would allow air to enter the system.
