During ALS Step 3, which monitoring modalities are used?

• A. ECG and End-Tidal CO2 monitoring
• B. SpO2 and Blood Pressure monitoring
• C. Only SpO2 monitoring
• D. Ultrasound monitoring

Answer: (A)

During ALS Step 3, the focus is on advanced airway management and continuous physiologic monitoring. ECG provides real-time information on heart rhythm during resuscitation, while capnography (end-tidal CO2) is essential for confirming endotracheal tube placement and assessing ventilation quality while chest compressions are ongoing. These two monitoring modalities are foundational for Step 3 because they directly guide airway patency, ventilation effectiveness, and rhythm management. SpO2 and blood pressure are important, but SpO2 can be unreliable during CPR due to low perfusion, and ultrasound is not a routine monitoring modality in this step.
