After 20 years in EMS, (see how it starts immediately - Emergency Medical Services), The whole bloody damned field is nothing but acronyms for as far as the eye can see.
From BPM - Beats per minute, to ABC - Airway, Breathing, circulation, (which today is more like ACB - Airway, Circulation, Breathing) to OPQRST - Onset, provoke/pallation, Quality, Region/Radiation, Severity, Time to A-Fib - Atrial Fibrillation to SOB - Shortness of Breath.
I hate them all…
Nope. It’s taught OPQRST.
