The ArmBoard can be shaped to achieve more prominent radial artery access. A slight bend of the ArmBoard will provide the patient with a more natural hand/wrist position. The small and x-small sizes can be shaped to accommodate an infant's wrist or heel. The ArmBoards are covered in soft, comfortable material and fastened to the wrist/heel with adjustable straps with hook and loop closure which allows the clinician easy access to the catheter side.
