Patients who are scheduled to receive living donor liver transplantation will be monitored with a radial and femoral arterial line. A pulmonary artery catheter will also be placed and central venous pressure, cardiac index, and cardiac output will also be monitored. Simultaneously, on the middle finger of the hand where the radial artery is monitored, Clearsight (Edwards Lifesciences, Irvine, CA), a finger cuff, is placed and noninvasive blood pressure, cardiac output, cardiac index are measured. Using the VitalDB program, the parameters measured with the invasive methods and the parameters obtained by the noninvasive method are compared.
