Turn it (All the Way) Up: Flush Rate O2 for Pre-Oxygenation

Background: There has been a lot of buzz recently about the importance of pre-oxygenation in emergency airway management.  The recent publication of the ENDAO trial [2], a randomized clinical trial of ApOx vs no ApOx also emphasized this point.  In the review article accompanying this trial by John Sackles [3] he brought up the point that most patients in this study were intubated in less than 1 – 2 minutes.  In this scenario, preoxygenation alone would likely provide an adequate oxygen reservoir to prevent hypoxemia and that apneic oxygenation would only be helpful in the patients who exhausted their oxygen reserves (i.e. prolonged intubations). Although, apneic oxygenation has recently come into favor in emergency intubation, the issue that should maybe warrant greater consideration is proper preoxygenation. The optimal method of pre-oxygenation however, is often debated: bag-valve mask (BVM), nonrebreather (NRB), or simple face mask.  Read more →
