Exhaled nitric oxide in patients with obstructive sleep apnea syndrome
open access
Abstract
Methods: 119 (99 M, 20 F) consecutive patients of sleep laboratory participated in this study. Standard overnight sleep studies with polysomnography or portable screening device were carried out in the whole group: OSAS was diagnosed in 66 patients and 53 no-OSAS served as controls. FENO was measured on-line with a flow rate kept at 0.045-0.055 l/s, according to the recommendations of ATS using a chemiluminescence analyzer twice: before the sleep study (8-10 p.m.) and after termination of data collection (6-8 a.m.). There were no differences in age between patients and controls. Respiratory disturbance index (RDI) was 40.3±24.9 in patients and 3.7±2.8 in controls (p
