BACKGROUND
Although routine physical activity for individuals with COPD is recommended, there are inherent limitations of available oxygen delivery devices that may result in hypoxemia during activity. Changes in Medicare laws have resulted in an increased use of oxygen cylinders and a reduction in the use of liquid oxygen devices. The aim of this survey was to assess the impact of perceived satisfaction with various oxygen delivery devices on perceived mobility and quality of life (QOL) of oxygen-dependent subjects with COPD.
METHODS
A survey was developed to measure perceived satisfaction with current portable oxygen delivery devices, perceived mobility, and perceived QOL. The survey was deployed via a link posted on the COPD Foundation's COPD360SOCIAL social media site for 5 weeks, which resulted in the recruitment of 529 participants, of which 417 were included in the data analysis.
RESULTS
Quantile regression analysis revealed that the median perceived device satisfaction score was significantly higher in the liquid oxygen device group ( < .001) compared with the portable oxygen cylinder and portable oxygen concentrator (POC) groups. The median perceived mobility score was significantly higher in the liquid oxygen device group ( < .001) compared with the portable oxygen cylinder group, but not the POC group. The median QOL score was significantly higher in the liquid oxygen device group ( < .001) compared with the POC and portable oxygen cylinder groups. Moreover, partial least-squares structural equation modeling regression analysis showed that perceived mobility is significantly affected by perceived satisfaction with the long-term oxygen therapy (LTOT) device (adjusted R = 0.15, < .001), and perceived QOL is significantly affected by both perceived satisfaction with the LTOT device and perceived mobility (adjusted R = 0.45, < .001).
CONCLUSIONS
For individuals with COPD requiring LTOT, perceived satisfaction with a portable LTOT device significantly and positively affects perceived mobility and QOL.
背景
尽管建议慢性阻塞性肺疾病（COPD）患者进行日常体育活动，但现有的氧气输送设备存在固有局限性，可能导致活动期间出现低氧血症。医疗保险法律的变化导致氧气瓶的使用增加，而液氧设备的使用减少。本调查的目的是评估对各种氧气输送设备的感知满意度对依赖氧气的COPD患者的感知活动能力和生活质量（QOL）的影响。
方法
制定了一项调查，以测量对当前便携式氧气输送设备的感知满意度、感知活动能力和感知生活质量。该调查通过发布在COPD基金会的COPD360SOCIAL社交媒体网站上的链接进行了5周，共招募了529名参与者，其中417名纳入数据分析。
结果
分位数回归分析显示，与便携式氧气瓶和便携式制氧机（POC）组相比，液氧设备组的感知设备满意度中位数得分显著更高（<.001）。与便携式氧气瓶组相比，液氧设备组的感知活动能力中位数得分显著更高（<.001），但与POC组相比无显著差异。与POC组和便携式氧气瓶组相比，液氧设备组的生活质量中位数得分显著更高（<.001）。此外，偏最小二乘结构方程建模回归分析表明，感知活动能力受长期氧疗（LTOT）设备感知满意度的显著影响（调整后R = 0.15，<.001），感知生活质量受LTOT设备感知满意度和感知活动能力两者的显著影响（调整后R = 0.45，<.001）。
结论
对于需要LTOT的COPD患者，对便携式LTOT设备的感知满意度对感知活动能力和生活质量有显著的积极影响。
