QUICK SETUP OF THE CHEETAH MEDICAL SYSTEM In five easy steps Turn On The Cheetah Medical Monitor Press the power button until the system turns on DETERMINATION OF FLUID STATUS* DETERMINATION OF FLUID STATUS* Access the PLR Wizard Access the Bolus Test Wizard Conduct a reversible fluid challenge in order to determine fluid responsiveness Conduct a fluid challenge in order to determine fluid responsiveness Passive Leg Raise (PLR) The PLR wizard will display the peak hemodynamic change from the baseline over a 3 min time span CHEETAH NICOM Menu >> Protocol >> PLR Test 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 selection/titration Menu >> Protocol >> Bolus Test STARLING SV 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 45° •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 Bolus Test Results Prewired Sensors Main Menu Screen Select ‘New Patient’ 30°-45° Use a wedge cushion for ease of use and standardization Interpretation: Fluid Responsive ∆SVI ≥ 10% Enter Patient Details Fluid Responsive: SVI & organ perfusion will likely increase in response to IV fluids3-4 Input: ID, Age, Height, Weight and Gender. Select Finish A positive test suggests that the patient is on the ascending limb of the Frank-Starling curve 17.1% PLR Not Fluid Responsive Fluid Responsive A negative test suggests that the patient is on the flat limb of the Frank-Starling curve If inserted data is incorrect: select ‘Update Details’and re-enter data SVI ∆ = 2.0% Example of a negative PLR Test indicating no fluid responsiveness 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 Interpretation: Fluid Responsive ∆SVI ≥ 10% Frank-Starling curve Interpretation: Not Fluid Responsive ∆SVI < 10% 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 1 Cecconi M, Parsons AK, Rhodes A.
