Intervention

Device:
• high flow nasal canulae
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.
• Ventury mask
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Ptdi swing	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	PTPdi	on effort at isotime, comparison between HFNC and VM of diaphragmatic pressure time product during a respiratory cycle (PTPdi)	during the intervention, at isotime
Secondary	PTPoeso	on effort at isotime, comparison between HFNC and VM of the respiratory "Pressure Time Product" during a respiratory cycle (PTPoeso)	during the intervention, at isotime
Secondary	Poeso swing	on effort at isotime, comparison between HFNC and VM of variation of oesophagal pressure between the base state and the peak (Poeso swing)	during the intervention, at isotime
Secondary	DeltaPtdi/DeltaEAdi	on effort at isotime, comparison between HFNC and VM of the electromechanical coupling of the diaphragm (ratio of variation of the transdiaphragmatic pressure by the variation of electrical activity of the diaphragm (EAdi) between the start of inspiration and the end of expiration, (DeltaPtdi/DeltaEAdi)	during the intervention, at isotime
Secondary	SmO2	on effort at isotime, comparison between HFNC and VM of the measurement of tissue saturation in oxygen (SmO2) by "Near Infrared Spectrometry" (NIRS)	during the intervention, at isotime
Secondary	TcCO2	on effort at isotime, comparison between HFNC and VM of transcutaneous CO2 measurement (TcCO2)	during the intervention, at isotime
Secondary	Tlim	Comparison of endurance time (Tlim) between HFNC and VM	during the intervention, at the end of endurance test
