Use this scenаriо tо аnswer questiоns 34-39: A 51-yeаr-old patient is reporting stomach pain and chest discomfort that is radiating down their left arm. The patient had coronary artery stents placed 5 days ago. The patient’s skin is pale and cool to the touch. Their blood pressure is 72/46 mm Hg, mean arterial pressure is 55 mm Hg, heart rate is 188/min, respiratory rate is 28 breaths per minute, and SpO2 is 89% on room air. The ECG shows ventricular tachycardia. While you administer supplemental oxygen, the patient suddenly loses consciousness, and the ECG monitor shows ventricular fibrillation. The patient has been intubated and shortly after gains return of spontaneous circulation but is not able to follow commands. Their vitals show heart rate of 110/min, mean arterial pressure of 70 mm Hg, respiratory rate of 6 breaths per minute, and oxygen saturation of 93% on 100% oxygen. A 12-lead ECG reveals ST-segment elevation in leads V2 through V4. While awaiting transfer to the cath lab for percutaneous coronary intervention, which post–cardiac arrest care intervention do you choose next for this patient?
