  1. CO, cardiac output; CVP, central venous pressure; EF, ejection fraction; FAC, fractional area change; LAP, left atrial pressure; LVEDV, left ventricular end-diastolic volume; MR, mitral regurgitation; PAC, pulmonary artery catheter; PAP, pulmonary artery pressure; RVEDV, right ventricular end-diastolic volume; SF, shortening fraction; SV, stroke volume; SvO2, mixed venous oxygen saturation; TEE, transoesophageal echocardiography; TR, tricuspid regurgitation; wp, wedge pressure.
