NCT03102827

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 COMPARATOR

high-flow oxygen therapy administered during first night, ambient air without high-flow therapy (placebo) administered during second night

Drug: Oxygen

Ambient air - oxygen

PLACEBO COMPARATOR

Ambient air without high-flow therapy (placebo) administered during first night , high-flow oxygen therapy administered during second night

Other: Placebo

Interventions

OxygenDRUG

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.
