Abstract

Long-term oxygen therapy can increase life expectancy in hypoxemic patients with COPD. Accurate identification of hypoxemia requires arterial blood gas measurements. Pulse oximetry can be used to measure trends in oxygenation, oxygen needs, and oxygen requirements during exercise and sleep. A detailed oxygen prescription indicates: (1) the oxygen dose (L/min), (2) the number of hours per day that oxygen therapy is required, (3) the dose required during exercise, (4) the oxygen supply system: concentrator, compressed gas cylinder, or liquid oxygen reservoir, and (5) the delivery device: nasal cannula, demand-flow device, reservoir cannula, or transtracheal oxygen catheter.

摘要

长期氧疗可提高慢性阻塞性肺疾病（COPD）低氧血症患者的预期寿命。准确识别低氧血症需要进行动脉血气测量。脉搏血氧饱和度测定可用于测量运动和睡眠期间的氧合趋势、氧气需求和需氧量。详细的氧疗处方应注明：（1）氧剂量（升/分钟），（2）每天所需氧疗的小时数，（3）运动期间所需的剂量，（4）氧气供应系统：制氧机、压缩气瓶或液氧储存器，以及（5）输送装置：鼻导管、按需流量装置、储氧导管或经气管氧导管。
