Version 3.1
ITBVI = ITBV / PBSA
where ITBVI = Intrathoracic Blood Volume Index (ml/m
2
)
ITBV = Intrathoracic Blood Volume (ml)
PBSA = Predicted Body Surface Area (m²)
SVV = (SV
max
– SV
min
) / SV
mean
where SVV = Stroke Volume Variation (%)
SV
max
= Mean value of 4 maximum stroke volumes of the last
30 seconds (ml)
SV
min
= Mean value of 4 minimum stroke volumes of the last
30 seconds (ml)
SV
mean
= Mean value of stroke volumes over the last 30 seconds (ml)
PPV = (PP
max
– PP
min
) / PP
mean
where PPV = Pulse Pressure Variation (%)
PP = Pulse Pressure (AP
sys
- AP
dia
)
AP
sys
= Systolic Arterial Pressure
AP
dia
= Diastolic Arterial Pressure
PP
max
= Mean value of 4 maximum Pulse Pressures of the last 30 seconds
(mmHg)
PP
min
= Mean value of 4 minimum Pulse Pressures of the last 30 seconds
(mmHg)
PP
mean
= Mean value of pulse pressure over the last 30 seconds (mmHg)

SVR = [(MAP – CVP) / CO] x 80
where SVR = Systemic Vascular Resistance (dynxsxcm
-5
)
MAP = Mean Arterial Pressure (mmHg)
CVP = Central Venous Pressure (mmHg)
CO = Cardiac Output (l/min)
SVRI = [(MAP-CVP) / CI] x 80
where SVRI = Systemic Vascular Resistance Index (dynxsxcm
-5
xm
2
)
MAP = Mean Arterial Pressure (mmHg)
CVP = Central Venous Pressure (mmHg)
CI = Cardiac Index (l/min/m
