Measuring CO Cardiac Output (CO) (Optional)
18 - 6 V Series Operating Instructions
18.3 Measuring CO
18.3.1 Optimizing CO Measurements
1. From the PA catheter package insert, verify the correct computation constant for the catheter
type, injectate volume, and injectate temperature. Change the computation constant if it is
different than the monitor’s factory default of 0.500.
2. Verify proper PA catheter positioning.
3. Purge system of air.
4. Use correct injectate port.
18.3.2 Auto and Manual CO Measurements
In Auto Start mode (when Auto Start is set to On), the monitor automatically takes the CO
measurement after establishing a baseline blood temperature. In this mode, it is not necessary to
select the Start CO button in the CO Run dialog. After a bolus injection, the V 12/V 21 computes the
CO and is ready to start another bolus injection.
In Manual mode (when Auto Start is set to Off), the monitor takes the CO measurement after
selecting the Start CO button in the CO Run dialog. After a bolus injection, the V 12/V 21 computes
the CO and is ready to start another bolus injection.
18.3.3 Taking CO Measurements
1. Connect the CO cable to the CO connector in the CO module.
2. If not previously done, follow the steps in the "Configuring the CO Parameter" on page 18-4 or
skip to following step.
3. Select the CO digital tile.
4. Select the Setup tab.
5. Enter the Height, Weight, and CO Source.
6. Select the C.O. Run button.
The Cardiac Output dialog displays (shown in FIGURE 18-4).
NOTE: CCO measurements take precedence over CO measurements. If you are
using both CO and CCO, and want to take a CO measurement, change
the CO Source to Module and then run the measurement. To reengage
CCO as the priority measurement, change the CO Source to Auto.
