Fig 1.
Boxplots plots comparing cardiac function index (CFI) derived from jugular indicator injection (CFI_jug), from femoral injection without activation of a potential correction by the device (CFI_fem_uncor), from femoral injection with activation of a potential correction by the device (CFI_fem_cor) and from femoral injection without activation of a potential correction by the device, but corrected by the previously suggested formula (CFI_fem_uncor_form).
CFI_fem_uncor_form was corrected using the formula suggested for correction of femoral indicator injection derived GEDVI: GEDVIcorrected [ml/m2] = 0.539 * GEDVIuncorrected—15.17 + 24.49 * CIuncorrected 2.311* BWideal. CFI_fem_uncor_form was calculated by multiplying CFI_fem_uncor with the ratio GEDVuncorrected/GEDVcorrected. GEDV(I): global end-diastolic volume (index).

Bland Altman plot comparing cardiac function index CFI_fem_uncor derived from femoral injection without activation of a potential correction by the device to the gold standard measurement CFI_jug using a jugular CVC for indicator injection.
Fig 3.
Bland Altman plot comparing cardiac function index CFI_fem_cor derived from femoral injection after activiation of a potential correction by the device to the gold standard measurement CFI_jug using a jugular CVC for indicator injection.
Fig 4.
Bland Altman plot comparing cardiac function index CFI derived from femoral indicator injection with (CFI_fem_cor) and without (CFI_fem_uncor) activation of a potential correction by the device.
Fig 5.
Bland Altman plot comparing cardiac function index CFI_jug derived from jugular indicator injection to cardiac function index CFI-fem_uncor_form which was derived from femoral indicator injection without activation of a potential correction by the device, but corrected with the formula suggested for correction of femoral indicator injection derived global end-diastolic volume index GEDVI: GEDVIcorrected [mL / m2] = 0.539 * GEDVIuncorrected—15.17 + 24.49 * CIuncorrected 2.311* BWideal. CFI_fem_uncor_form was calculated by multiplying CFI_fem_uncor with the ratio GEDVuncorrected/GEDVcorrected.
GEDV(I): global end-diastolic volume (index). CI: Cardiac index.
Table 4.
Categories of cardiac function index (CFI) classified as decreased (CFI <4.5 min-1), normal (4.5≤ CFI ≤6.5 min-1) and increased (CFI >6.5 min-1).
