Which capability is typically associated with ALS but not with BLS?

• A. Cardiac rhythm interpretation
• B. Rescue breaths
• C. Use of AED
• D. Walking patients to the ambulance

Answer: (A)

Cardiac rhythm interpretation is an ALS capability because it requires reading an ECG strip, recognizing specific rhythms (like VF, VT, or asystole), and making clinical decisions based on that interpretation. BLS providers rely on an AED to analyze rhythm and decide whether to shock, so they don’t manually interpret rhythms themselves. Rescue breaths and the use of an AED are within the BLS scope, and simply walking patients to the ambulance isn’t a defined advanced capability. Therefore, rhythm interpretation is the feature that distinguishes ALS from BLS.
