Physical Examination:

Patient brought in ambulance for stabilization at ER. Family member reports that arrived home and encountered patient sweating with psychomotor agitation, moaning, and precordial pain. Upon arriving, paramedics determined that patient was hypoxemic and with inaudible blood pressure. Transported to the ER, patient arrived with respiratory failure – gasping. It was performed orotracheal intubation, escalating to cardiorespiratory arrest at pulseless electrical activity. Reanimation maneuvers with spontaneous circulation return during a total of 5 (3-2-2-2-2) cardiorespiratory arrest cycles and administration of adrenaline, bicarbonate and crystalloids, and noradrenaline. We are hospitalizing patient. We don’t have a mechanical ventilator. ECG showed ST segment elevation in aVR lead and diffuse ST segment depression.
