问题 问答题 简答题

新生儿长期给氧应注意什么?

答案

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。
