Anesthetic Hypotension

Editor's Note: A version of this algorithm was published in the March 2017 issue of Clinician's Brief. It was revised and republished in 2019.

*Permissive hypercapnia is a ventilation strategy in which oxygenation is prioritized over expired carbon dioxide. Higher than normal carbon dioxide levels are allowed because of low ventilation that preserves the lungs.

AV = atrioventricular, BOAS = brachycephalic obstructive airway syndrome, CO = cardiac output, HR = heart rate, IPPV = intermittent positive pressure ventilation, MABP = mean arterial blood pressure, PEEP = positive end-expiratory pressure, SIRS = systemic inflammatory response syndrome, SV = stroke volume, SVR = systemic vascular resistance
