Clear the airway

Check the patient, ensure airway is clear


Give oxygen

If not already receiving high concentration oxygen start it now


Check equipment

Saturation probe disconnected / poor contact

Oxygen source disconnected / exhausted

Endotracheal tube blocked / displaced

Ventilation device malfunction
 


When the airway is clear & equipment
failure is not the cause...


Identify and treat the cause of hypoxia

This may be respiratory or cardiovascular

REMEMBER
A pulse oximeter measures oxygenation NOT ventilation
The CO2 may still be rising, indicating repiratory failure,
when the oximetry reading is near 100%
