CO Monitoring
16-6
select this option to stop the measurement. The measured
CO and CI will be displayed.
„ CANCEL Selecting this option during a measurement cancels the
measurement. Selecting it after a measurement deletes the
measurement result.
„ REC This option allows you to print the measurement curve using
the recorder.
„ Scale Y This option allows you to change the scale of Y-axis
(temperature).
Three levels: 0 - 0.5
℃ , 0 - 1 ℃ and 0 - 2.0 ℃ .
You can adjust the scale according to the temperature
difference. The smaller the scale is, the larger the curve will
be.
„ Scale X This option allows you to change the scale of X-axis (time).
Two levels: 0 - 30S and 0 - 60S.
If you start measurement in the 0 - 30s level, it will be
switched to 0 - 60s level automatically if the measurement
cannot be finished within 30 seconds. After the switch, no
further adjustment can be made to the X-axis.
„ EDIT This option allows you to enter WINDOW FOR C.O. EDIT.
„ EXIT This option allows you exit WINDOW FOR CO
MEASUREMENT.
Measurement Procedure
1. The cardio output measurement can be started when the prompt information
“Ready for new measurement” appears in the window.
2. Select the START option, and then start the injection.
3. The thermodilution curve, the current blood temperature and the injectate
temperature are displayed in the process of the measurement.
4. The curve drawing stops automatically when the measurement is completed. At
the same time, the C.O. (Cardiac output) and the C.I. (Cardiac Index) are
calculated and displayed in the window. The monitor also displays the CO
value in the CO parameter window.
To ensure the accuracy of the measurement, it is suggested two consecutive
measurements be performed at an interval. The length of the interval can be set in
the C.O. SETUP menu (time unit: second). The remaining time to the next
measurement is displayed at the position of 2 in Figure 16-3. The next measurement
cannot be performed until the time reduces to zero and the “Ready for new
measurement” prompt information appears.
