The aim of this study was to study the pattern of the use of chronic domiciliary oxigenotherapy (CDO) in Catalonia, Spain.
A transversal study including 110 patients randomly selected from a list of all the subjects with CDO (n = 3,585) was made. A domiciliary survey on the characteristics of the indication for CDO and its fulfillment was carried out. Two pulsioximetries were also performed one breathing room air and another with oxigen.
Of the 70 eligible patients the following factors were simultaneously observed in only 14 (20% of the total): adequate indication for CDO, use of oxigen at a flow which corrected the hypoxemia, and prescription fulfillment. The most important cause of inadequate usage of CDO was inappropriate indication since only 19 patients (27%) presented SaO2 less than or equal to 88%. Hypoxemia was not corrected in four of these 19 patients. Thirty-seven percent of the total admitted bad fulfillment, bot only one of the 15 patients with SaO2 less than or equal to 88% and in whom hypoxemia was corrected, recognized bad fulfillment. Sixty-nine percent of the patients had a document explaining the way and length of time they should receive the oxigen.
The inappropriate indication of CDO is the main factor influencing the low effectiveness of chronic domiciliary oxigenotherapy in Catalonia.
本研究旨在调查西班牙加泰罗尼亚地区慢性家庭氧疗（CDO）的使用模式。
进行了一项横断面研究，从所有接受CDO治疗的患者名单（n = 3585）中随机选取110例患者。对CDO适应症的特征及其落实情况进行了家庭调查。同时进行了两次脉搏血氧饱和度测量，一次在呼吸室内空气时测量，另一次在吸氧时测量。
在70例符合条件的患者中，仅14例（占总数的20%）同时具备以下因素：CDO适应症充分、以能纠正低氧血症的流量吸氧以及医嘱落实情况良好。CDO使用不当的最重要原因是适应症不恰当，因为只有19例患者（27%）的动脉血氧饱和度（SaO2）小于或等于88%。这19例患者中有4例低氧血症未得到纠正。总共有37%的患者承认医嘱落实情况不佳，但在15例SaO2小于或等于88%且低氧血症得到纠正的患者中，只有1例认识到医嘱落实情况不佳。69%的患者有一份文件解释他们吸氧的方式和时间长度。
CDO适应症不恰当是影响加泰罗尼亚地区慢性家庭氧疗效果不佳的主要因素。
