Fluid Bolus and Hemodynamic Response
The Bolus Wizard will report on the peak
hemodynamic change within the chosen
time-frame. Useful also to capture
hemodynamic impact of drug

Place & Connect Sensors
Baseline:
Semi-Recumbent position
Place sensors on patient’s body and attach
connectors according to their color
Obtain 3 min of monitoring
for average baseline SVI
The CHEETAH Sensors should be positioned around the
heart. The exact location is flexible. See sensor
package for more information
If the last three SVI readings are
stable, the PLR Test can be operated
from the Challenge stage
Start the Bolus/ Drug
Infusion

•Activate the Bolus Test
function of the CHEETAH monitor.
•Administer a 3ml/kg IV
Bolus over 5min1
Challenge: Leg Raise
For optimal results ensure stable
hemodynamics for 2 min prior to
the bolus
Obtain 3 min of monitoring
for SVI peak value

Patient Information
CHEETAH Sensors should be replaced with a new set of sensors after 48 hours
of use. Remember to preform a re-calibration after sensor replacement and
once daily.
A positive test suggests
that the patient is on the
ascending limb of the
Frank-Starling curve1-2
SVI ∆ = 17.1%
Example of a positive Bolus Test indicating
fluid responsiveness
Interpretation: Not Fluid
Responsive ∆SVI < 10%
Not Fluid Responsive: SVI will
remain flat or hardly increase in
response to IV fluids
Confirm data accuracy,
select ‘Run’ then press ‘OK’
to begin test

Review Data & Start Test
•At the end of the bolus challenge, stop the Bolus Test
•Note the peak change in the Wizard Report
A negative test suggests that
the patient is on the flat limb
of the Frank-Starling curve
SVI ∆ = 2.0%
Example of a negative Bolus Test indicating
no fluid responsiveness
