The patient was admitted for an avr/mvr/cabg +/- tvr/myectomy.The patient transferred to cvor without incident.While setting up the bypass equipment, the perfusionist inadvertently connected the oxygenator inlet tubing to the outlet adapter and the oxygenator outlet tubing to the inlet adapter.Interchanging these lines was not a concern with the previous equipment model.The new model; however, has a filter that now requires blood to flow in one direction.The equipment has some color coding to assist with set-up, but still permits the tubing to lock with the incorrect adapter.
