In 49 (81,7\%) patients was diagnosed vasculomotor rhinitis, accompanied by hypertrophy of maxilloturbinal bone in 44 (81,7\%) cases, in 30 \% of patients had deviated septum.Correlation analysis revealed significant direct connection of medium strength between left inspiratory nasal flow (LINF) and apnea index (AI) {\textendash} (r = 0,428, p \< 0,05), between LINF and awakenings/hour (r = 0,493, p \< 0,05), between right inspiratory nasal flow (RINF) and AI (r = 0,575, p \< 0,05), between LINF and apnea-hypoapnea index (AHI) (r = 0,494, p \< 0,05).Conclusion: in severe COPD patients aerodynamic impairments of upper airways due to vasomotor rhinitis complicated by hypertrophy of the maxilloturbinal bone and deviation of nasal septum conditioned appearance and severity of respiratory disorders during sleep.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/42/Suppl_57/P3671}, eprint = {https://erj.ersjournals.com/content/42/Suppl_57/P3671.full.pdf}, journal = {European Respiratory Journal} }
