Fig. 1From: Threshold adjusted vagus nerve stimulation after asphyxial cardiac arrest results in neuroprotection and improved survivalThe experimental design for No VNS/VNS after 12 min asphyxial cardiac arrest and resuscitation on 72 h survival (Upper panel). Changes in heart rate before and after VNS indicating 15–20% reduction in basal heart rate as a threshold (Lower panel). (CPR = cardiopulmonary resuscitation; ROSC = return of spontaneous circulation; tVNS = threshold adjusted vagus nerve stimulation; mNDS = modified neurological deficit scoreBack to article page
