Noninvasive Ventilation versus Nonrebreather Bag–Valve Mask to Achieve Preoxygenation before Intubation of Hypoxic Patients

To the Editor:

In their recent article, Baillard and colleagues analyze preoxygenation for a 3-min period prior to a rapid sequence intubation in hypoxic, critically ill patients (1). They compare the application of preoxygenation with pressure support ventilation delivered by an ICU ventilator (NIV) through a face mask with an FIO2 of 1.0 and a PEEP level of 5 cm H2O versus a nonrebreather bag–valve mask. They demonstrate that preoxygenation using NIV is more effective at reducing arterial oxyhemoglobin desaturation than the usual preoxygenation procedure with nonrebreather bag–valve mask driven by 15 L/min oxygen.

We found an important detail lacking. Is their self-inflating bag suitably mounted with an oxygen reservoir? In recent work (2), we demonstrated that significant differences existed between a system with an oxygen reservoir and one without it (the FIO2 that obtained with or without the reservoir diminished from 0.99 to 0.65, respectively). If the authors of the study used a system without reservoir, this simple fact could explain the differences they found. This information would be most helpful to correctly interpret the study's conclusions.
