慢性肺疾患病人的缺氧需长时间氧疗,这项治疗也可在家庭内进行。1.家庭长时间氧疗的好处:(1)可以延长低氧血症病人的存活时间,经验证明严重低氧血症病人如果持续给氧可使病死率降低30%～40%,而且延长存活时间与每天追加给氧的小时数成正比,每天吸氧19h 的这一组病人的死亡率是每天吸氧12h 组的1/2。(2)增进病人运动的耐力,氧疗后病人步行距离,活动平板踏车试验时间等增加,改进氧输送和氧 Chronic lung disease patients need long time hypoxia oxygen therapy, this treatment can also be carried out in the family. 1. Long-term home oxygen therapy benefits: (1) can prolong the survival time of patients with hypoxemia, the experience shows that patients with severe hypoxemia if continued oxygen can reduce mortality by 30% to 40%, and prolong survival The time is proportional to the number of hours oxygen is added daily, and the daily mortality of this group of patients who inhaled oxygen for 19 hours per day is one-half of that in the 12-hour group. (2) to improve the endurance of patient movement, patient walking distance after oxygen therapy, treadmill treadmill activity increased, improve oxygen delivery and oxygen
