Points and Pearls Excerpt
-
Initiating best-practice ventilation management in the ED has been shown to decrease duration of ventilation, hospital stay, and mortality.
-
Failure to optimize oxygenation and perfusion prior to intubation and mechanical ventilation has been associated with an increased risk of peri-intubation cardiac arrest.
-
Hyperoxia in acutely ill patients is harmful. Large reviews have demonstrated an increase in mortality with a liberal oxygenation strategy compared to a more conservative approach.
-
Start the newly mechanically ventilated patient at 100% FiO2, but then rapidly titrate down the oxygen until the oxygen saturation is 93%-96%.
