Schematics (A) and monitor display (B) of the tested cardiac output (CO) measurement device. The y axis C (%) represents the percentage concentration of saline in the arterial blood while the x axis is time (seconds). ACVI, active circulation volume index; BSA, body surface area; CBVI, central blood volume index; CI, cardiac index; CVP, central venous pressure; HR, heart rate; SVI, stroke volume index; SVRI, systemic vascular resistance index; TEDVI, total end diastolic volume index; TEF, total ejection fraction.
