RT Journal A1 Kochanek PM, Bayır H T1 TItrating oxygen during and after cardiopulmonary resuscitation JF JAMA JO JAMA YR 2010 FD June 2 VO 303 IS 21 SP 2190 OP 2191 DO 10.1001/jama.2010.715 UL http://dx.doi.org/10.1001/jama.2010.715 AB Several investigations have rekindled important concern that administration of 100% oxygen during and early after resuscitation from experimental cardiopulmonary arrest might be deleterious to the brain. In a canine model of ventricular fibrillation cardiopulmonary arrest, use of 100% oxygen compared with use of room air early during resuscitation was associated with increased neuronal death in selectively vulnerable brain regions and worse neurological outcome.1 Several studies have focused on oxidative injury to key mitochondrial enzymes (such as pyruvate dehydrogenase or manganese superoxide dismutase) or mitochondrial lipids (such as cardiolipin) in mediating these deleterious effects.2- 4
