6. When you see the message [
Ready for New Measurement
], select the [
Start
] button
and then inject the solution within 4 seconds. As shown in the figure above, during the
measurement, the currently measured thermodilution curve is displayed on the upper
part. At the end of the measurement, the thermodilution curve is transferred to one of
the 6 measurement windows on the lower part and the monitor prompts you to wait for
a certain period of time before starting a new measurement.
7. When you see the message [
Ready for New Measurement
], repeat step 5 until you
have completed the measurements you want to perform. 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.
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.
