Impact of High-level Oxygen Therapy on the Reconditioning of Type I Hypoxemic Respiratory Insufficiency Patients in Intensive Care

The measurements are carried out on a max effort of 12 minutes on a cyclometer ergometer with a constant load (Motomed viva2 light). A first effort is made with a Venturi type mask whose Inspired Fraction in Oxygen (FiO2) is set for a pulsated oxygen saturation (SpO2) greater than or equal to 85%, and then a second at 2h interval with high-throughput googles (Optiflow) with the corresponding FiO2.
