For adults with asthma and obstructive sleep apnea, CPAP is associated with improved asthma control, quality of life, and lung function, according to a study published online Oct 12 in Allergy.

Researchers conducted a prospective study to examine asthma outcomes after six months of CPAP in 99 adults with asthma with OSAS. The researchers found that from baseline to six months there was a decrease in the mean score of the ACQ, in the percentage of patients with uncontrolled asthma (41.4% to 17.2%), and in the percentage of patients with asthma attacks in the six months prior to and following treatment (35.4% to 17.2%).
