Positioning
Raise the bed to a comfortable height for you (ie, so you may stand straight while doing the procedure). Place the patient supine or in Trendelenburg position (bed tilted with the head down 10 to 20°) to distend the axillary vein and prevent air embolism. The arm may comfortably rest at the patient's side, and the head is kept neutral. Stand at the side of the bed.
