It can monitor kinetic parameters such as SVV, CI and SV continuously and dynamically, the monitoring accuracy was confirmed by many studies.6-8 Waldron6 and other studies showed that there was good correlation between the data of NICOM and esophageal doppler monitor (EDM), and the missing data was less than EDM.
During HIPEC, LVEF significantly decreased (Figure 3), and measurements of intravascular filling (SVV, PPV, and IVC diameter) suggested significant hypovolaemia.
There was a precipitous fall of BP and CVP in the initial period of enterolysis, together with an increase of SVV (Figure 2).
Caloric test, SVV test, HIT, and vHIT were normal and did not show any deficit in VOR.
SVV received funding for this work from the National Research Foundation.

The transpulmonary thermodilution provided the following: (1) preload parameters: global end-diastolic volume index (GEDVI), intrathoracic blood volume index (ITBVI), and stroke volume variation (SVV); (2) cardiac parameters: CO, cardiac index (CI), and global ejection fraction (GEF); (3) afterload parameters: systemic vascular resistance index (SVRI); and (4) lung parameters: extravascular lung water index (EVLWI) and pulmonary vascular permeability index (PVPI).
Based on the magnitude of the positive pressure ventilation-induced pulse pressure variation (PPV) or stroke volume variation (SVV), "volume responsiveness" can be defined, which predicts a substantial elevation in cardiac output in response to a fluid bolus [2].
Sixty-five (86%) patients had small vessel vasculitis (SVV) and 11 (14%) had medium sized vessel vasculitis (MVV).
