HAPICánula Nasal de Alto Flujo de Oxígeno vs. Máscara Facial de Bolsa de No Rebreathing de Alta FiO2 para Oxigenación en la Intubación Traqueal

Pre-oxygenation is ensured in our ICU with a high FiO2 nonrebreathing facemask, except in patients already under high flow nasal cannula oxygen therapy because of acute hypoxemic respiratory failure. A nasal catheter is positioned to ensure a low oxygen flow during laryngoscopy. Whether or not all patients should benefit from high flow nasal cannula oxygen therapy for pre-oxygenation remains unknown. In order to improve quality of care delivered to our patients and in anticipation of a change in our practice, we decided to record prospectively oxygen parameters during and immediately of intubation using a facemask and to compare them with parameters obtained in patients intubated after our change in practice. The change of practice consists in the systematic use of high flow nasal cannula oxygen therapy to ensure pre and during procedure (tracheal intubation)oxygenation.
