Description
1
Sys/Dia/MAP
Display
The Systolic, Mean Arterial and Diastolic pressures are derived from the
arterial blood pressure waveform. MAP is derived by integrating the BP
waveform and computing the average.
See Systolic, Mean Arterial and Diastolic Pressures on page 28.
2
CO Display
The product of stroke volume and heart rate. The Cardiac Output (CO) is the
amount of blood pumped by the heart in a minute.
See Cardiac Output on page 28.
3
SV Display
Stroke Volume is the amount of blood ejected by the heart in a given beat;
updated beat-by-beat based on the LiDCO pulse power analysis algorithm.
See Stroke Volume on page 29.
4
HR Display
The number of beats per minute of the heart.
See Heart Rate on page 28.
5
SVR Display
The quotient of pressure and cardiac output. Systemic Vascular Resistance
(SVR) reflects the resistance to flow and is calculated as the quotient of
pressure and cardiac output.
See Systemic Vascular Resistance on page 30.
6
SVV Display
Stroke Volume Variation (SVV) is the maximum Stroke Volume (SV) minus the
minimum SV divided by the mean SV across at least one respiratory cycle (10
seconds). Values below 8% indicate the patient is unlikely to respond to fluids
values above 13% indicate the patient will respond to fluids.
See Stroke Volume Variation on page 29.
7
PPV Display
The maximum Pulse Pressure (PP) minus the minimum PP divided by the
mean PP across at least one respiratory cycle (10 seconds). Values below
10% indicate the patient is unlikely to respond to fluids values above 15%
indicate the patient will respond to fluids.
See Pulse Pressure Variation on page 29.
8
DO
2
Display
Oxygen Delivery (DO
2
) is the product of cardiac output and oxygen
concentration. The DO
2
is the amount oxygen delivered to the tissues.
See Oxygen Delivery on page 29.
9
VO
2
Display
Oxygen Consumption (VO
2
) is a measure of the oxygen consumed by tissues.
VO
2
is calculated from CO, Hemoglobin (Hb or SpHb) and arterial saturation
(SaO
2
or SpO
2
) and venous saturation (SvO
2
).
See Oxygen Consumption on page 29.
10
HRV Display
Heart Rate Variation (HRV) is the standard deviation in heart rate over a
respiratory cycle (10 sec) divided by the mean HR. Values above 10% will not
display the SVV or PPV.
See Heart Rate Variation on page 28.
