A 38 year-old man (Ethiopian refugee) with untreated HIV and past history of TB, presents to the emergency department (ED) with anterior chest pain, shortness of breath and hypotension. He was seen 3 days prior by a walk-in clinic and referred to the ED with chest pain and ECG showing pericarditis, but did not attend the ED until symptoms were severe. In the ED, patient quickly progresses to profound shock and has a PEA arrest. POCUS will show a large pericardial effusion and tamponade. Team members are to initiate CPR, manage the arrest and treat the effusion using bedside pericardiocentesis in order to obtain return of spontaneous circulation (ROSC).
