6. Proceed as follows.
In [Manual] measure mode, select the [Start] button and then inject the solution quickly when you see the
message [Ready for new set of measurement]. As shown in the figure above, during the measurement, the
currently measured thermodilution curve is displayed. At the end of the measurement, the thermodilution
curve is transferred to one of the 6 measurement windows and the monitor prompts you to wait for a certain
period of time before starting a new measurement.
In [Auto] measure mode, the monitor consecutively takes C.O. measurements automatically without the need
for pressing the [Start] button between two measurements. A new thermodilution measurement is possible as
soon as the message [Inject now!] is displayed on the screen. The monitor automatically detects further
thermodilution measurements.
7. Consecutively take 3 to 5 single measurements as instructed by Step 6.
A maximum of 6 measurements can be stored. If you perform more than six measurements without rejecting any, the
oldest will automatically be deleted when a seventh curve is stored. Select from the 6 measurement curves and the
system will automatically calculate and display the averaged C.O. and C.I. values. Then select the [Accept Average]
button to accept and store the averaged values.
When injecting, the stopcock to the PA catheter is open and the stopcock to the injectate solution is closed. After the
measurement is completed, turn off the stopcock to the PA catheter and turn on the stopcock to the injectate solution,
and then draw the injectate solution into the injectate syringe.
