COPD Linked to Low Blood Oxygen Levels, Poor Sleep

Researchers have found that people with chronic obstructive pulmonary disease, or COPD, are more likely to have low arterial blood oxygen levels as well as fatigue, sleepiness and an impaired quality of life.

The research team also found that individuals with COPD have a more difficult time getting to sleep and have more interrupted sleep. These sleeping troubles are likely tied to the low arterial blood oxygen levels (also known as daytime hypoxemia).
