The MAP, CI, SVI, and
SVV in responders significantly increased after fluid loading [Table 2].
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.

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).
