A patient is brough to the ED with EMS. He was found in cardiac arrest, but ROSC was achieved after 5 minutes of CPR. His BP is 60/42 despite running fluids and a faint pulse is palpable. The team is planning a definite airway, and you have asked for a norepinephrine infusion to be prepared. What is the best strategy to maintain blood pressure and prevent rearrest before the drip is running?
