Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: 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.
Enhed: 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.
Eksperimentel: 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.
Enhed: 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.
