Failure pattern reviewChoose the visible problem.SpO₂ fallingOpen hypoxia pathway.BP/MAP fallingOpen hypotension pathway.No/low EtCO₂Tube, circulation, or equipment.Vent alarm / high pressureResistance, compliance, circuit, dyssynchrony.Abnormal vital signsTranslate vitals into a failure bucket.

First four moves

  • Call for help and assign roles.
  • Disconnect from ventilator and bag with 100% O₂/PEEP if unstable and appropriate.
  • Verify tube position/depth and waveform EtCO₂.
  • Search DOPES: displacement, obstruction, pneumothorax/patient, equipment, stacked breaths.

Do not miss

  • Right mainstem, esophageal tube, tube obstruction, tension pneumothorax, auto-PEEP, medication-related hypotension, RV failure.
