A Randomised Controlled Trial of High-Flow Nasal Oxygen Versus Standard Oxygen Therapy in Critically Ill Immunocompromised Patients

"Devices used to treat spontaneously ventilating patients in the ICU who require supplemental oxygen. They deliver either~* low-flow oxygen \[including nasal cannula, Ventimask® without Venturi effect, and non-rebreather mask\]~* or medium-flow oxygen \[Venturi masks and medium-flow facemasks\]"

The intervention is the use of a device that allows to deliver high flow humidified and warmed oxygen. The device used is the Optiflow™ (Fisher\&Paykel, Courtaboeuf, France).
