Averaging Cardiac Output
This function computes the average using the data from up to five, good,
displayed curves. Curves labeled as “bad” are not included in the average.
You can perform cardiac output averaging as soon as the system has measured
and displayed at least two acceptable curves.
When the cardiac output averaging is complete:
• The CO zone displays the curves used in the average, the averaged cardiac
output, and cardiac index values.
• The time and date of the last curve displays.
Clearing Cardiac Output Curves
Occasionally you may want to delete a curve prior to averaging or storing. All
curves, or only selected curves, can be cleared. If a “bad” curve is displayed when
you select to average, store, or clear another displayed curve, the “bad” curve is
also cleared.
When you clear an individual CO curve or all CO curves, the INJECT WHEN
READY message is displayed in the first available curve position, so the curves
displayed on the screen may not appear in numerical order.
Storing Cardiac Output Curves
This feature enables you to store all of the acceptable, displayed curves at once
or individually. The system stores the vital signs and cardiac output value it
acquired at the end of curve acquisition, along with the time it displayed each
curve. The curves clear from the screen as they are stored. The system does not
store “bad” curves. After you store the acceptable curves, the system clears all
curves from the screen.
Stopping Curve Drawing and Acquisition
This feature enables you to stop the curve drawing and data acquisition of a
cardiac output curve in progress. The STOP CURVE key only appears during
curve drawing. Touching this key will invalidate all curve data for that injection.
Once the blood temperature is again stable, the INJECT WHEN READY message
will appear if in AUTO mode. The TOUCH START THEN INJECT message will
appear if in MANUAL mode.
