November 22, 2022 updated by: ADIR Association

Evaluation of the Physiological Effects of High Flow Nasal Canulae Oxygen Therapy During Exercise in Patients With Fibrosing Interstitial Lung Diseases

in this study, the investigators aim to describe the effects of highflow nasal canulae oxygen therapy (HFNC) on respiratory muscle function during exercise in patients with fibrosing interstitial lung diseases (ILD) during an endurance test

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Venturi mask
Patients will be placed under oxygen therapy with Venturi mask at a constant flow of 15L/min and a set FiO2 of 50%. The real FiO2 will be mesured in the mask at rest.
Ventury mask is a oxygen therapy technic which allows the administration with a mask of oxygen with a flow up to 15L/Min and a monitored FiO2.
Experimental: High flow nasal canulae
Patients will be placed under high flow nasal canulae oxygen therapy with a constant flow of 50L/min and the real FiO2 provided by Venturi mask.
high flow nasal canulae is a oxygen therapy technic which allows the administration of warmed and humidified oxygen with a flow up to 50L/Min and a monitored FiO2. Physiological previous studies reported various effects of this technic especially on work of breathing. In our study the investigators aim to test this physiological property during exercise.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Ptdi swing
Time Frame: during the intervention, at isotime
To compare the change in transdiaphragmatic pressure between baseline and peak during inspiration (Ptdi swing) between HFNC and VM in patients with fibrosing Interstitial Lung Disease in stable state, at isotime.
during the intervention, at isotime

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
