Patients with suspected obstructive sleep apnea (OSA) may no longer have to spend an expensive and uncomfortable night at a sleep center to monitor their sleep-disordered breathing. According to new research, those who performed sleep testing in their home with portable monitors showed similar improvements after three months of treatment with continuous positive airway pressure (CPAP) in daytime function as compared to patients who underwent overnight testing in a sleep center. Furthermore, patient adherence to CPAP over the first three months of treatment was similar in patients with OSA who received home versus in-lab testing.
