18.6.1 Preparing for C.O. Measurement
1. Connect the C.O. cable to the C.O. module and thermistor connector, making sure the C.O. numeric area is
displayed on the monitor’s main screen.
2. Follow the hospital’s policy and procedures to prepare the patient for the C.O. measurement.
3. Follow the manufacturer’s instructions to set up the catheter and other accessories.
4. Check that all the accessories are properly connected.
• For an in-line probe setup, make sure the in-line sensor is securely connected to the tubing. For the
bath probe setup, make sure the bath probe is correctly sensing the injectate temperature.
18.6.2 Setting C.O. Measurement
Before performing the C.O. measurement, follow this procedure:
1. Select the C.O. numeric area to enter the C.O. Measure menu.
2. Select the Setup.
3. Perform the following check or setup:
â—† Check if the height and weight are appropriate for your patient. Change if necessary. The patient's
height and weight values are required for determining cardiac index (C.I.).
â—† Check that the correct computation constant is entered. The computation constant has a close
relationship with the entered injectate volume, injectate probe type (in-line probe or bath probe) and
