Diagnosis

Unexplained oxygen desaturation

  1. Call for help

    • Ask: "Who will be the crisis manager?"
    • Crisis manager designates checklist reader

  2. Turn FiO2 to 100% at high gas flows

    • Confirm inspired FiO2 = 100% on gas analyzer
    • Confirm presence of end-tidal CO2

  3. Hand-ventilate to assess compliance

  4. Listen to breath sounds

  5. Check...

    • Blood pressure, pulse, airway pressures
    • Capnogram waveform
    • Endotracheal tube/supraglottic device position
    • Pulse oximeter placement and limb perfusion
    • Circuit integrity: disconnection, kinks, holes

  6. Consider initial stabilization actions

    • Suction secretions
    • Remove circuit and use self-inflating bag
    • Alveolar recruitment maneuver and PEEP titration
    • Bronchodilator therapy
    • Deepen anesthetic and paralysis
    • Optimize positioning and insufflation pressure

  7. Consider causes - see DIFFERENTIAL Diagnosis

  8. If hypoxia persists, consider ECMO

Patient weight

Between 30 kg and 250 kg

Reset the checklist?

Checked steps, the timer and this crisis log are cleared. The patient’s weight is kept.

Finish the crisis?

The timer pauses, and you can review the case and the event log.
