Cardiac output
2. Follow your care unit’s policy and procedures for positioning the patient for the
C.O. measurement.
3. Follow the catheter manufacturer's instructions to set up the in-line or bath
probe patient cables.
4. For an in-line setup, make sure the in-line sensor is securely connected to the
tubing.
5. For the bath probe setup, make sure the bath probe is correctly sensing the
injectate temperature.
Checking the C.O. measurement
1. Check that the monitor recognizes cable connections (activates the display) and
all C.O. menu selections are available.
2. Remember that in order to get Cardiac Index (C.I.) you must first enter the patient
demographics.
3. For E-modules, check that the message Press Start C.O. appears on the screen.
Using the C.O. measurement
Entering patient data for the C.I. value
The patient's height and weight values are required for determining cardiac index (C.I.).
1. Select the cardiac output parameter window.
2. Select Demographics from the Measurement tab.
3. Set the patient’s height and weight.
The BSA value is calculated automatically once the height and weight have been
selected.
4. You can return to the Cardiac Output menu by selecting Previous Menu .
C.O. measurement modes
C.O. measurements can be taken using the automatic or manual measurement
modes. Both measurement modes allow you to use up to six C.O. measurements
for calculating a C.O. average.
You can confirm the C.O. measurements within 15 minutes from the start of the first
thermodilution measurement, so even if you leave the menu the measurements will
not disappear during this time.
Taking an automatic C.O. measurement
PDM and TRAM: When measuring C.O. using the automatic mode, the monitor
averages approximately 8.5 seconds of the patient’s blood temperature before
establishing a stable baseline and displaying the
Inject When Ready message.
E-modules: When measuring C.O. using the automatic mode, new measurements can
be taken when the
Press Start C.O. Serial message displays.
Holding the injectate syringe by the plunger, not the barrel, improves measurement
accuracy.
