Brief Summary
To demonstrate the effectiveness and safety of nocturnal ventilation with oxygen (HFT - high-flow-therapy) for the treatment of CSA in patients with HFrEF compared to placebo (patient will breathe ambient air via nasal cannula that is not connected to the high-flow-device).

Outcome Measures
Primary Outcomes (1)
Reduction of hypoxemic burden
Reduction of hypoxemic burden \>50% compared to baseline using oxygen-HFT versus placebo
From date of enrolment until end of therapy phase (day 3). Hypoxemic burden is determined several times during this period.
Study Arms (2)
Oxygen - ambient air
ACTIVE COMPARATORhigh-flow oxygen therapy administered during first night, ambient air without high-flow therapy (placebo) administered during second night
Ambient air - oxygen
PLACEBO COMPARATORAmbient air without high-flow therapy (placebo) administered during first night , high-flow oxygen therapy administered during second night
Interventions
Patients will receive oxygen with humidified air, fully saturated at 37° C at a flow rate of 20- 50 L/min. The ratio of oxygen and ambient air (FiO2) will be increased stepwise depending on patient's oxygen saturation.
Ambient air without high-flow therapy administered during first night
