The pheresis tubing from the kit was loaded properly into the pheresis machine and the patient was connected to the tubing and pheresis machine.The treatment had been started.The machine alarm sounded, and the nurse observed that the tubing above the centrifuge was twisted.It then broke apart and resulted in a blood leak from the broken tubing.The pheresis treatment was stopped and the patient was safely disconnected from the pheresis equipment.However, there is infection risk from the disruption in the patient/pheresis connection.There was minimal blood loss from the patient but there was blood lost from the donor blood unit which was used as primer.The donor blood unit was also exposed and had to be discarded.
