Clinical Trial Summary

Assessment of the lung hyperinflation by bodypletysmography in patients with obstructive sleep apnoea treated with continuous positive airway pressure therapy.

Clinical Trial Description


Obstructive sleep apnoea (OSA) is characterized by repetitive closure of upper airways leading to apnoea (complete airflow cessation) or hypopnoea (airflow limitation > 50% + blood oxygen desaturation > 3% or airflow limitation > 30% blood oxygen desaturation > 4%). The prevalence of lung hyperinflations in sleep apnoea patients and effect of continuous positive airway pressure (CPAP) therapy is not known.


Subjects included in the study will be obstructive sleep apnoea (OSA) patients diagnosed by respiratory polysomnography performed in the Sleep Laboratory, Department of Respiratory Medicine, University Hospital Olomouc.

Bodypletysmography will be performed in the time of OSA diagnosis and after 3 months of CPAP therapy.

Data will be statistically evaluated after completion of the target number of subjects. ;
