A steris field service technician arrived onsite, inspected the table, and found the table was operating properly.The technician confirmed that the patient was repositioned more toward one end of the surgical table.When the patient's weight shifted, the table's feet came off of the floor.The 4085 patient positioning instructions quick reference guide shows a suggested position for the same type of procedure in which the table is not in full slide to the head, but rather more to the center of the table.Also section 1, safety precautions, of the operator manual states, "with patient in normal or reverse orientation, table in trendelenburg and slide at head limit, center tabletop before attempting to raise table to level or move into reverse trendelenburg." therefore the table operated as designed and would not reverse trendelenburg before the table was repositioned to the center.Although the reported event was able to be duplicated, this issue is attributed to improper patient positioning.The distribution of patient weight was improper and therefore the tipping was not considered to be a malfunction of the table.Steris conducted in-service training with the user facility about proper positioning and operation of the 4085 surgical table.
