Podcast 831: O2 Targets

Podcast 831: O2 Targets

Contributor: Aaron Lessen,MD

Educational Pearls:

  • Recent study looked at mechanically ventilated patients in ED and ICU to determine if O2 saturation level impacted patient outcomes
    • 2541 patients randomized to one of three target O2 saturation levels
      • Low: 90% (Range: 88-92%)
      • Intermediate: 94% (Range: 92-96%)
      • High: 98% (Range: 96-100%)
    • Outcome indicators
      • Primary: Number of days alive and ventilator free by day 28 of hospital admission
      • Secondary: Mortality at 28 days
    • No significant difference was seen for either primary or secondary outcomes between all three groups at 28 days
  • This study shows that the target oxygenation level is not likely to significantly impact outcomes in mechanically ventilated patients in the ED
