Twenty percent of the total died during sleep and in 26% death was unexpected. A lower arterial carbon dioxide tension (Pa,CO2), less oxygen usage per 24 h, and increased incidence of arrhythmias were seen in those patients who died suddenly. Drug therapy was not related to unexpected death.
What percentage of smokers get COPD?
About 10 to 15 percent of smokers develop COPD, but the optimal strategy to identify those most at risk is unknown. Geijer and colleagues conducted a prospective cohort study of men living in a small Dutch town to better understand the rate of progression to COPD and the factors that influence this change in smokers.
How long do you have to smoke to get COPD?
This study has examined the risk of developing of COPD in a general population throughout an observation period of 25 years. Our estimates indicate that, after 25 years of smoking, at least 25% of smokers without initial disease will have clinically significant COPD and 30–40% will have any COPD.

What is the 6 minute walk test for COPD?
The use of the 6 min walk test (6MWT) as a clinical tool to assess patients with COPD is of interest (8,9). The 6MWT is used to evaluate exercise capacity. It is simple to perform and correlates well with more sophisticated tests requiring a treadmill or cycle ergometer (8,10).
Does drinking a lot of water help COPD?
As previously stated, for people with COPD, excessive, sticky mucus can make breathing difficult. Drinking enough water can thin the mucus, making it easier to cough up. However, there are more benefits to staying hydrated with COPD. Drinking enough water can also help people with COPD fight off infections better.
What happens if you have COPD and still smoke?
Smoking continues to damage the lungs even after COPD develops, worsening the disease and triggering exacerbations (sudden airway narrowing and severe respiratory distress). Exacerbations can be life-threatening and can add to underlying disease severity.
