Calculation Results
Window
Displays the calculation results within the current
calculation range.
 Dmax: indicates the maximum IVC inner diameter within
a respiratory cycle.
 Dmin: indicates the minimum IVC inner diameter within
a respiratory cycle.
 IVC CI = (Dmax-Dmin)/Dmax
 IVC DI = (Dmax-Dmin)/Dmin
 IVCV = (Dmax-Dmin)/[(Dmax+Dmin)/2]
