慢性阻塞性肺病（COPD）病人長期處於低氧血症（Hypoxemia）狀態。為了適應這種慢性缺氧，末梢組織（如手指、腳趾）會進行代償性增生，導致指甲床角度變形，即所謂的杵狀指（Clubbing）。這是 COPD 的典型臨床體徵。其他選項如呼吸性鹼中毒或低碳酸血症，通常與急性過度換氣有關，非 COPD 的慢性特徵。
Clients with COPD are chronically hypoxemic. To adapt to chronic hypoxia, peripheral tissues (such as fingers and toes) undergo compensatory proliferation, leading to a deformed nail-bed angle known as clubbing. This is a classic clinical sign of COPD. Other options such as respiratory alkalosis or hypocapnia are usually related to acute hyperventilation rather than chronic features of COPD.
