Performing PiCCO C.O. Measurements

13 Monitoring Cardiac Output

Measuring C. O. Using the PiCCO Method

8Check that the correct arterial catheter constant is selected.

If the catheter is recognized by the monitor, the catheter constant is automatically displayed and cannot be changed manually. If it is not recognized, in the C.O. procedure window, select CathCt and use the pop-up keypad to enter the correct value. The catheter constant is usually written either on the catheter or on the catheter packaging.

9Make sure that the injectate volume setting matches the injectate volume you will use. To change the volume, in the C.O. procedure window, select InjVol and select the correct injectate volume from the pop-up list.

If there is a problem with the volume or temperature you have chosen, the monitor will issue a curve alert message to inform you of this.

10If you are measuring CCO or CCI, check that the correct pressure source is selected in the Setup CCO menu. The pressure label under CCO from must match the pressure measured with the arterial catheter. To change the pressure source, select CCO from to call up a list of available pressure labels and select the correct label.

11If you are measuring CCO or CCI, verify that the correct alarm source is selected in the menu item Alarms From. To change the alarm source, select Alarms From and choose either CCO or CCI.

Always wait for the monitor to indicate readiness for the next step before proceeding.

If you are measuring CCO, all measurements should be conducted within 15 minutes. Older measurements “expire” for CCO calibration.

1Enter the C.O. procedure window.

2When you see the message ...Ready for new measurement, start the measurement by selecting the pop-up key Start C.O. or pressing the Start hardkey on the C.O. module, or pressing the remote start switch.

3When you hear the ready tone and see the message ...Stable baseline, inject now!, inject the solution into the CVP catheter.

At the end of the measurement the thermodilution curve, cardiac output, index values, ITBV and EVLW values and any curve alerts are displayed and a message will appear “...Wait before starting new measurement”.

4When you see the ...Ready for new measurement message, repeat the procedure until you have completed the measurements you want to perform. You can perform a maximum of 6 measurements before editing. If you perform more than 6 measurements without rejecting any, the oldest will automatically be deleted when a 7th curve is stored.

Editing PiCCO C.O. Measurements

It is important to identify and reject erroneous trials, as the monitor uses all the measurement trial values you do not reject to calculate the averaged cardiac output.

1Review the trials. Irregular trials or trials marked with a “?” should be reviewed carefully. Consider the similarity of the values and the shape of the C.O. curve. A normal C.O. curve has one smooth peak and returns to the temperature baseline level after the peak.

2Reject unsatisfactory trials: use the Select Trial pop-up key to move between trials, then select the Accept Reject pop-up key to accept or reject trials. If you are using a touch screen
