老年患者家庭氧疗的注意事项

2021-07-26 15:08:55

慢性呼吸系统疾病和持续低氧血症的病人可以在家中进行氧疗。家庭氧疗一般采用氧气瓶和制氧机，对改善病人的健康状况，提高生活质量和运动耐力有显著疗效。但在家中进行氧疗时须注意以下问题：

1.合理选择吸氧时间。对严重慢阻肺，伴明确肺功能异常、氧分压持续低于60毫米汞柱的病人，每日应给予15小时以上的氧疗；对部分病人平时无或仅有轻度低氧血症，在活动、紧张或劳累时，短时间给氧可减轻“气短”的不适感。　　

2.注意控制氧气流量。一般为1～2升／分钟，且应调好流量再使用。因为高流量吸氧可加重慢阻肺病人的二氧化碳蓄积，引发肺性脑病。　

3.注意用氧安全最重要。供氧装置应防震、防油、防火、防热。 4.注意氧气的湿化。湿化瓶内应加1／2的冷开水。　

5.氧气瓶内氧气不能用尽，一般需留1mPa，以防再充气时灰尘杂质进入瓶内引起爆炸。　

6.鼻导管、鼻塞、湿化瓶等应定期消毒。　

7.购买制氧机的病人应仔细阅读说明书后再使用。
