Detailed Description

Chronic obstructive pulmonary disease (COPD) is a growing global health concern, causing considerable health-related costs and increased mortality. COPD is nowadays considered a complex, heterogeneous and systemic condition.

In the late stage of the disease, non-invasive ventilation (NIV) is widely prescribed either to treat acute hypercapnic respiratory failure during COPD exacerbations or for long term home management.

A meta-analysis has shown that higher daytime PaCO2 occurred in home NIV treated COPD patients when NIV compliance is less than 5 h/day. Thus, an optimal NIV adherence is a key target for controlling nocturnal and diurnal hypoventilation and improving prognosis.

COPD is the clinical scenario during which a good NIV adherence is difficult to achieve. Particularly, in COPDs exhibiting hyperinflation, NIV can aggravate dynamic hyperinflation resulting in unrewarded inspiratory efforts, poor sleep and low NIV compliance. Alternatives to NIV are then desirable in this specific subgroup of hypercapnic COPD with poor adherence to NIV.

During this trial, stable COPD patients treated by long term home Non-Invasive Ventilation (NIV) treatment following French national recommendations and exhibiting a NIV compliance of (less than 5 hours and more than 1 hour) per day in the last 3 months prior to inclusion will be randomized via a secure electronic website to either continue with their current NIV treatment or receive the nasal high flow (NHF) treatment delivered by myAirvo2 during 3 months Nasal High-Flow (NHF) is a treatment delivering heated, humidified, and optionally oxygen-enriched air at high flow rates through a nasal cannula. The main physiologic effects of NHF are an improvement in gas exchanges including a reduction in hypercapnia, an optimization in breathing patterns with a reduction of work of breathing. Nasal High-Flow (NHF) is delivered via a comfortable nasal interface and has demonstrated good treatment adherence.

The investigators hypothesize that in COPD-related hypercapnic chronic respiratory failure with limited compliance to NIV (less than 5 hours per night), nasal High-Flow (NHF) will be non-inferior for controlling nocturnal hypoventilation and might improve daytime subjective patients centered outcomes, physical activity and nocturnal adherence to treatment.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Non Invasive Ventilation device group

The patients in the NIV arm will receive treatment as in their usual care with an additional educational session of one hour for improving compliance.

Device: Non Invasive Ventilation
Participants randomized in the Non Invasive Ventilation group will receive treatment as in their usual care.

Other: Education session
Participants randomized in the Non Invasive Ventilation group will receive an additional educational session of one hour for improving compliance.

Experimental: Nasal High Flow (MyAirvo) device group

The patients in the NHF arm will receive NHF treatment and two hours training adaptation session will be conducted in the hospital.

Device: Nasal High Flow installation
Participants randomized in NHF group will receive the nasal high flow (NHF) treatment delivered by myAirvo2. Nasal High-Flow (NHF) is a treatment delivering heated, humidified, and optionally oxygen-enriched, air at high flow rates through a nasal cannula. The physiologic effects of NHF are an improvement in gas exchanges including a reduction in hypercarbia an optimization in breathing patterns with a reduction of work of breathing and high compliance as delivered via a comfortable nasal interface

  • MyAirvo Device
  • Other: Training session
    The patients in the Nasal High Flow (MyAirvo) arm will receive two hours training adaptation session in the hospital

    Outcome Measures

    Primary Outcome Measures

    1. Changes on nocturnal parameters with the nasal high-flow (NHF) compared to non-invasive ventilation in patients with a COPD-related hypercapnic respiratory failure. [between night at day 1 (baseline) and night at day 90 (3 months after)]

      Differences in mean overnight transcutaneous PtCO2 measurement

    Secondary Outcome Measures

    1. Evaluation the impact of nasal high-flow (NHF) on other nocturnal parameters compared to non-invasive ventilation ± LTOT compared to non-invasive ventilation in patients with a COPD-related hypercapnic respiratory failure. [between night at day 1 (baseline) and night at day 90 (3 months after)]

      Maximum PtCO2

    2. Treatment adherence [between night at day 1 (baseline) and night at day 90 (3 months after)]

      Treatment adherence measured objectively by download of NIV software data and for NHF (myAirvo2) by hour meter & daily average of usage (screen display)

    3. Daytime blood gas values in ambient air [between day 0 (inclusion) and day 97 (end of the study)]

      PaCO2 & PaO2 in ambient air will be measured by blood gas sample in NHF group compared de NIV group

    4. Other nocturnal parameter [between night at day 1 (baseline) and night at day 90 (3 months after)]

      Overnight Sp02 will be evaluated by nocturnal oximetry at home in order to determine: mean nocturnal SaO2, nadir nocturnal SaO2, cumulative time spent below 90% of SaO2 (CT<90%), Oxygen Desaturation Index.

    5. Physical activity [for 7 days from the day 1 and for 7 days from the day 90]

      An actimetry will allow evaluating physical activity (number of steps)
