Oxygenation goals

  • In recent pearls we have talked about 'lung protective' ventilation strategies to reduce volutrauma, barotrauma, and oxygen toxicity.
  • Using 'lung protective' strategies, such as low tidal volumes, results in higher levels of CO2 and a lower pH.  These are tolerated in favor of lower and safer alveolar pressures.
  • In addition to higher pCO2 values and lower pH, oxygenation goals are slightly lower than conventional teaching.
  • In these patients, you want to maintain SpO2 > 88% and PaO2 > 55 mm Hg.
