In the appropriate clinical setting, and where time allows a combination of the following may assist your decision.

  • Resp rate > 30 breaths per minute

  • Abnormal oxygenation as indicated by:

      • PaO2 <75 mmHg on an FiO2 > 1.4 (40% O2)

      • PaO2 : FiO2 ratio < 150

  • Depressed minute ventilation as indicated by:

      • PaO2 > 60 mmHg
