LAFD EMS Revised Patient Disposition Policy (PDP) Practice Test

Continuous capnography during any ventilation provides real-time feedback on airway status and how well the patient is being ventilated. This is crucial because ETCO2 reflects the amount of carbon dioxide being eliminated with each breath, which helps confirm that the airway is patent and that ventilation is effective. It also helps you detect problems quickly, such as a mispositioned airway, tube dislodgement, hypoventilation, or returning circulation during CPR.

That’s why the correct statement is that ETCO2 should be recorded whenever ventilation assistance is provided. It isn’t limited to intubation, nor tied to low oxygen saturation alone, and it isn’t exclusive to pediatric patients. ETCO2 monitoring complements SpO2 and gives immediate, actionable insight into ventilation status across all patients receiving assistance.
