[{'content': 'Preterm Neonate target oxygen saturation is ? \nSelect and explain. \nA. 91-95 %, B. > 95%, C. 85-89%, D. <80%', 'role': 'user'}, {'content': 'Answer: A \nExplanation: *Warm humidified oxygen should be provided at a concentration initially sufficient to keep aerial oxygen pressure between 50 and 70 mm Hg (91-95% saturation) in order to maintain normal tissue oxygenation while minimizing the risk of oxygen toxicity.Hyperoxia may also contribute to lung injury in preterm infants. However, a lower target range of oxygenation (85-89%), as compared with a higher range (91-95%) increases moality, and does not alter rates of BPD, BPD/death, blindness, or neurodevelopmental impairment. Therefore, the currently recommended range of oxygen saturation targets is 91-95%. Ref : Nelson 9 thedition pg 854', 'role': 'assistant'}]
