Measure
Angiotensin
The angiotensin arm will receive angiotensin II acetate at an initial dose of 20ng/kg/min, titratable during the study (6 hours) for MAP goals as outlined in the protocol.
Control
Control patients will receive placebo intravenously equal in duration, color and volume to the intervention arm's angiotensin II.
