Common Traps
Agonal breathing trap
Gasping is abnormal ≠ Start arrest pathway
Pulse delay trap
Max 10 seconds ≠ Unsure means CPR
Post-shock trap
Do not pulse-check ≠ Resume CPR immediately
No-shock trap
AED no shock ≠ Resume CPR immediately
Ventilation trap
Visible chest rise ≠ Avoid overventilation
Opioid trap
Naloxone helps breathing ≠ CPR still first
PEA trap
Organized rhythm ≠ Still pulseless arrest
Asystole trap
Confirm leads ≠ Do not defib
Brady block trap
Atropine may fail ≠ Pacing may be needed
Tachy shock trap
Pulse gets sync ≠ Pulseless gets defib
Adenosine trap
Regular SVT only ≠ Avoid unstable delay
Team trap
Silent tasks fail ≠ Close every loop
