Measuring Cardiac Output
2000966-386D Dash™ 3000/4000/5000 12-3
Measuring
To verify that you are ready to measure CO, follow this procedure.
1. Admit the patient to the monitor.
2. Connect the patient cable to the Temp/CO patient connector on the monitor.
3. Position the patient.
4. Verify the in-line sensor is connected to the tubing or that the bath probe is
correctly sensing injectate temperature.
5. Verify that patient data displays in the CO parameter window.
6. Verify the monitor is ready for cardiac output trials.
7. Verify that a good quality waveform displays.
8. Adjust the control settings as necessary.
9. Verify that the swan catheter vendor, size and constant are correct.
Control Settings
To adjust the control settings for the patient admitted to the monitor, select the CO
parameter window label. Then select any of the following options and make the
desired changes.
NOTE
All changes are temporary and revert to the factory or custom defaults when the
patient is discharged. To permanently change the these settings, refer to Defining
Custom Defaults on page 3-7.
NOTE
If you change the selections for USE, CATHETER, INJECT TEMP, SIZE or
INJECT VOL during or after beginning a cardiac trial, the trials saved in the
history are deleted. Saved calculations are not deleted or changed. All new trials
and calculations use the new selected values.
Option Function
DELETE CO TRIALS Select and delete trials not wanted. Up to four trials are
saved; when a new trial is made, the oldest trial is deleted.
CARDIAC CALCS Access the cardiac calculations program. For more
information, refer to Cardiac Calculations on page 6-8.
CARDIAC OUTPUT NOW Perform one manual cardiac output measurement when the
“INJECT NOW!” message displays. Manual injections may
be preferred for patients with extreme blood temperature
fluctuations.
BT LIMITS Select the blood temperature alarm limits and unit of
measurement. An alarm sounds when a value occurs
outside of these limits.
