† Cardiac performance was tested with a combination of volume loading and lower-extremity compression by an anti-g suit in 11 patients scheduled for aortic operations. The mean response of cardiac output (CO) to volume loading and anti-g suit compression was flat, despite a significant rise in pulmonary capillary wedge pressure (PCWP). Right to left intrapulmonary shunt was unchanged by the testing procedure. The low mean wedge pressure reemphasizes the need for preoperative insertion of a Swan-Ganz catheter and for measurement of PCWP and CO to provide optimal fluid treatment to each patient who undergoes an aortic reconstructive operation.
