NCT06007495

Brief Summary

The goal of this pilot randomized cross-over study is to compare the effect of a full-face mask with expiratory washout to a conventional full face mask on non-invasive ventilation (NIV) in patients with acute hypercapnic, and acute hypoxemic, respiratory failure. The main questions it aims to answer are:

  • Does a mask with expiratory washout improve minute ventilation in patients using non-invasive ventilation compared with a conventional single-limb NIV mask
  • How does a mask with expiratory washout affect respiratory variables compared with a dual-limb NIV mask. Participants already prescribed NIV will undergo 3 arms of the investigation in a randomized order:
  • Single-limb NIV with investigation mask (with expiratory washout)
  • Single-limb NIV with conventional mask
  • Dual-limb NIV with conventional mask

Outcome Measures

Primary Outcomes (1)

  • Minute Ventilation

    Variations of the minute ventilation in the three different arms (Investigational mask, single-limb conventional, dual-limb conventional)

    Recorded at baseline and the end of each 30-minute period of non-invasive ventilation over 1 hour and 30 minutes of data measurement

Secondary Outcomes (5)

  • Tidal Volume

    Recorded at baseline and the end of each 30-minute period of non-invasive ventilation over 1 hour and 30 minutes of data measurement

  • Respiratory Rate

    Recorded at baseline and the end of each 30-minute period of non-invasive ventilation over 1 hour and 30 minutes of data measurement

  • Blood gases

    Recorded at baseline and the end of each 30-minute period of non-invasive ventilation over 1 hour and 30 minutes of data measurement

  • Dyspnoea Score

    Recorded at baseline and the end of each 30-minute period of non-invasive ventilation over 1 hour and 30 minutes of data measurement

  • Mask Comfort Score

    Recorded at baseline and the end of each 30-minute period of non-invasive ventilation over 1 hour and 30 minutes of data measurement

Study Arms (3)

Single-limb non-invasive ventilation with expiratory washout

EXPERIMENTAL

In a random order, 30 minute period of non-invasive ventilation using the investigational mask, a vented full-face mask with expiratory washout

Device: Investigational full-face mask with expiratory washout

Single-limb non-invasive ventilation

ACTIVE COMPARATOR

In a random order, 30 minute period of non-invasive ventilation with a conventional vented full-face mask (RT077 or equivalent)

Device: Conventional full-face mask - single-limb

Dual-limb non-invasive ventilation

ACTIVE COMPARATOR

In a random order, 30 minute period of non-invasive ventilation with a conventional vented full-face mask (RT076 or equivalent)

Device: Conventional full-face mask - dual-limb

Interventions
