新生儿长期给氧应注意什么？
参考答案：
(1)掌握适应证：氧疗法应该用于有缺氧、发绀、窒息、惊厥等症状的患儿。
(2)密切观察病情变化：吸氧过程中一旦呼吸困难好转和青紫减轻，就应减小氧流量和输氧浓度。尽可能用间歇给氧，防止持续长期吸入高浓度氧，以防发生氧中毒。
(3)用鼻导管给氧时，氧流量1～2L／min，氧浓度25％～30％；严重缺氧者，氧流量5L／min。冬天．湿化瓶内水可加温，温湿的氧能减少对呼吸道粘膜的刺激。注意保持呼吸道和氧导管通畅。
(4)及时测定血气指标，尽可能用最低浓度给氧，使氧分压维持在6．7～10．6kPa。
(5)观察并记录呼吸频率及节律、体温、面色和肤色、尿量。
(6)严格执行消毒隔离技术，防止肺部感染。
