Central-to-peripheral gradients during CPB are consistent and unmodified by variables; extends CPB hemodynamic observations in CABG but leaves outcome effects open.
Do different cardioprotection strategies, flow types, or vasoactive drugs affect the central-to-peripheral arterial pressure gradient during cardiopulmonary bypass in patients undergoing CABG?
The central-to-peripheral arterial pressure gradient during cardiopulmonary bypass is a consistent phenomenon primarily occurring between the brachial and radial arteries, unaffected by common intraoperative variables or vasoactive agents.
