A 41-year-old woman requires manipulation of a displaced distal radius fracture in the Emergency Department. After procedural sedation is given, she does not remain fully alert, but she opens her eyes and purposefully moves her arm when asked. She also responds appropriately when the clinician lightly touches her shoulder and repeats the instruction. Her oxygen saturation remains stable, she is breathing spontaneously, and no airway intervention is required.
