The 2015 AHA Neonatal Resuscitation Guidelines update provides recommendations for several changes: 1. Positive pressure ventilation for preterm infants should include PEEP of 5cmH2O. Laryngeal masks are recommended when intubation is not feasible for infants >34 weeks. 2. Initiation of resuscitation for preterm infants should use low oxygen (21-30%) titrated to target saturation rather than high oxygen. Term infants should be initiated with room air. 3. Chest compressions are indicated if the heart rate is <60/minute despite ventilation. The 2-thumb technique is preferred for compressions. 4. Assessment of heart rate response is the best measure
