Effects of High-flow Oxygen Therapy and Non-invasive Ventilation on Lung Volumes and on Upper Airway (HONIVAH)
Respiratory Failure
About this trial
This is an interventional treatment trial for Respiratory Failure focused on measuring intensive care, non-invasive ventilation, high-flow nasal oxygen therapy, hypoxemic respiratory failure, upper airway
Eligibility Criteria
Inclusion Criteria: Patient with hypoxemia at any time of ICU stay defined as follow: standard oxygen therapy flow ≥ 3L/min to maintain a pulsed oxygen saturation ≥ 95% Adult (age ≥ 18 years) (2) A CT scan prescribed by the physician in charge of the patient as part of the exploration of the patient's pathology and not as part of a "dedicated" prescription for the study. Exclusion Criteria: NIV contraindication (need for immediate endotracheal intubation and mechanical ventilation; hemodynamic instability defined by systolic blood pressure < 90 mmHg or mean blood pressure < 65 mmHg, use of vasopressors; Glasgow Coma Scale score of 12 points or less) History of recent facial trauma not compatible with the use of nasal cannulas Pregnancy Refusal of study participation protected person Patient not affiliated to the social security system or not benefiting from such a system Lack of signed informed consent

Active Comparator
HFNC (Hight-flow oxygen therapy)
Non-invasive ventilation (NIV)
In the HFNC group, patients will receive HFNC oxygen therapy for 20 minutes. Oxygen will be passed through a heated humidifier and continuously delivered through medium or large nasal cannulas (OptiflowTM, Fisher and Paykel Healthcare) depending on patient anatomy, with a gas flow of 50 litres per minute and the FiO2 will be adjusted to maintain a SpO2 between 95% and 98%.
In the NIV Group, patients will receive NIV for 20 minutes delivered with a naso-buccal or face mask according to the patient's tolerance. The pressure-support level will be adjusted with the aim of an expired tidal volume of 6 to 8 ml per kilogram of predicted body weight, with a positive end-expiratory pressure (PEEP) of 5 cmH2O. The FiO2 will be adjusted to maintain a SpO2 between 95% and 98%.
