Hemodynamic management of hypotension during and after weaning from CPB

Hemodynamic management of hypotension during and after weaning from CPB
CVP PAP PADP or PAWP* Cardiac output Blood pressure LV function by TEE RV function by TEE Diagnosis Response
Low Low Low Low Low Normal or hyperdynamic Normal or hyperdynamic Hypovolemia Administer volume
Low or normal Low or normal Low or normal High Low Normal or hyperdynamic Normal or hyperdynamic Vasoplegia Administer vasopressor
High or normal High Low or normal High Low Normal Normal or hypocontractile Pulmonary hypertension Administer pulmonary vasodilator
High Normal or low Normal or high Low Low Normal Hypocontractile, often dilated Right ventricular dysfunction

Administer inotropic agent

Administer pulmonary vasodilator
Normal or high Normal or high High Low Low Hypocontractile, often dilated Normal Left ventricular dysfunction Administer inotropic agent
CPB: cardiopulmonary bypass; CVP: central venous pressure; PAP: pulmonary artery pressure; PADP: pulmonary artery diastolic pressure; PAWP: pulmonary artery wedge pressure; LV: left ventricular; TEE: transesophageal echocardiography; RV: right ventricular.
* PAWP should not be measured prior to neutralizing heparin following CPB. Initially, PADP is measured, the PADP may overestimate PAWP when patients have elevated pulmonary vascular resistance (eg, pulmonary hypertension).
¶ PADP or PAWP are indirect measures of LV filling pressure. With RV dysfunction and dilation, ventricular septal shift may increase LV filling pressure despite low or normal LV filling volume.
