  • Days −4 to −1 are preoperative and days 1 to 7 are postoperative. HB = head box oxygen; IPPV = intermittent positive pressure ventilation; CPAP = continuous positive airway pressure ventilation; A = apnoea; B = bradycardia; gs = gentle stimulation; vs = vigorous stimulation;↑ = increased; ↓ = decreased; O2 = oxygen.
