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
EXPERIMENTALIn a random order, 30 minute period of non-invasive ventilation using the investigational mask, a vented full-face mask with expiratory washout
Single-limb non-invasive ventilation
ACTIVE COMPARATORIn a random order, 30 minute period of non-invasive ventilation with a conventional vented full-face mask (RT077 or equivalent)
Dual-limb non-invasive ventilation
ACTIVE COMPARATORIn a random order, 30 minute period of non-invasive ventilation with a conventional vented full-face mask (RT076 or equivalent)
Interventions
With cross-over in randomized order, mask worn for 30 minutes with prescribed single-limb non-invasive ventilation
With cross-over in randomized order, conventional mask such as RT077, worn for 30 minutes with prescribed single-limb non-invasive ventilation
With cross-over in randomized order, conventional mask such as RT076, worn for 30 minutes with prescribed dual-limb non-invasive ventilation
