求助学术翻译

帮一个老外讲者翻译COPD方面的讲稿，有几点拿捏不准，请产品经理们多指点：
As maintenance treatment for COPD, basic treatment with long-acting anticholinergics accords with both national and international guidelines.
作为慢性阻塞性肺疾病(COPD)的维持治疗方法，使用长效抗胆碱药物的基础治疗必须符合国际性和全国性的指南。
These small airways, the bronchioles, are “suspended” in the surrounding alveoli, i.e. in the actual lung tissue, which forms a three-dimensional “net”.
这些小气道，即细支气管，悬吊于肺泡的包围中。也就是说在实际的肺组织中，这些细支气管形成了一个三维的“网”。
This structure can be most likened to a sponge. Due to the fact that the lung tissue that attaches itself to the walls of the bronchioles has a certain “elasticity”, the walls are pulled outwards, thereby expanding the bronchioles. This is the only force keeping the bronchioles open.
这一结构和海绵非常相像。 To be put on the last line?
依附于细支气管壁面上的肺组织，具有相当的“弹性”，因此，这些壁面由肺组织向外拉伸时，细支气管得到扩张。这是保持细支气管开放的唯一力量。
In emphysema, the alveolar walls are enlarged, and large air spaces have formed where the alveoli should be.
肺气肿情形下，肺泡壁扩张， 肺泡形成超出其限度的大的空气间。
This is called hyperinflation and can be measured as an increased residual volume (RV).
这被称作过度膨胀。过度膨胀可以通过残气量（RV）的增加来衡量。
A correctly performed examination provides a lot of information. With moderate COPD, we see here the typical boomerang-shaped curve. The curve for normal lung function shows no sign of obstruction.
正确完成的检查能够提供大量信息。我们在这儿可以看到中度慢性阻塞性肺疾病（COPD）典型的飞镖形状曲线。而正常肺功能的曲线，没有显示阻塞的迹象。
请问我的翻译拗口吗?
欢迎大家多指教！
谢谢！
