Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Nasal High flow therapy device

Experimental: Diagnostic PSG/PG, PSG w. nasal high flow therapy - All patients recruited will undergo a diagnostic sleep study, either a full in laboratory attended polysomnography (PSG), or an in-home polygraphy (PG). If respiratory insufficiencies with Cheyne-Stokes respiration (CSR) are detected, these patients will undergo an overnight in laboratory attended PSG on a nasal high flow therapy device to test the primary endpoint of this study. Patients without respiratory insufficiencies after the first PSG/PG will take no further part in the trial.


Treatment: Devices: Nasal High flow therapy device
Nasal high flow therapy via nasal cannula.
