Background:Tracheal intubation is a common procedure performed on critically ill patients. In these patients, there is a high risk of life-threatening complications associated with the procedure, with severe hypoxemia being one of the more common. Development of severe hypoxemia, in turn, increases the risk of post-intubation cardiac arrest. Therefore, optimal preoxygenation is an essential part of tracheal intubation to help stave off subsequent complications.
Both NIV and HFNC can provide a higher fraction of inspired oxygen than standard oxygen therapies. HFNC can provide continuous oxygen up to 70L/min via nasal prongs with the potential advantage of remaining in place for apneic oxygenation. NIV can also provide high flow oxygen but must be removed during the apneic phase of intubation. To date there has not been a study comparing NIV vs HFNC to reduce the incidence of severe hypoxemia during intubation until now; the FLORALI-2 trial....Read More
