新生儿对低氧刺激的反应能力差 ,缺氧更易导致细胞代谢和器官功能障碍 ,甚至威胁生命 ,提供足够氧浓度以提高氧分压和血液带氧的能力 ,从而保证组织氧供 ,消除或减少缺氧对机体的不利影响。氧疗就是在原发病和呼吸功能恢复之前 ,帮助患儿渡过疾病严重阶段 ,但若使用不当 ,则可 Neonatal hypoxia-induced poor response, hypoxia more easily lead to cell metabolism and organ dysfunction, and even life-threatening, provide enough oxygen concentration to improve oxygen partial pressure and blood oxygen capacity, thus ensuring tissue oxygen supply, elimination or Reduce the adverse effects of hypoxia on the body. Oxygen therapy is to help children through the serious stages of the disease before the primary disease and respiratory function are recovered, but if used improperly,
