ABC vs CAB

[Eithanhunt]

I'm sure this topic gets beat to death, but my professor says that priority is Airway Breathing Circulation (ABC) only for patients with respiratory issues, and that the priority switches to CAB otherwise.

I thought it was always ABC, unless you're going to perform CPR, only then it becomes CAB.

Clarification would be appreciated. Thank you.

You need to clarify with that instructor.

CAB is taught during BLS and ACLS. Even for a respiratory arrest, you start with CAB. If they have a good pulse you don't start compressions but you still check Circulation first.

General (awake and responsive) patient on the floor, basic assessment is ABC.

Also, with CAB, we add in Cspine precautions!
