When managing cardiac arrest, it is important to differentiate PEA, the presence of organized electrical activity without a pulse, from "pseudo-PEA,"where there is no pulse but there IS cardiac activity visualized on ultrasound.
Bottom Line: Pseudo-PEA is different from PEA. Utilize POCUS during your cardiac arrests to identify it and to help diagnose reversible causes, and treat it as a profound shock state with the appropriate supportive measures, i.e. pressors or inotropy.
