Operator Mode: When the Operator mode is selected the Timing bar displays the
inflation/deflation range and current timing settings.
This range is 0% to 120% of the R-R interval for all trigger modes. The distance
between vertical lines represents 10% of the R-R or AP interval. An expanding green or
red bar indicates the inflation and deflation set points. This bar changes to red during
Arterial Pressure triggering. The bar changes to yellow if deflation timing is set beyond
100% (100% to 120% only).
The patient's physiological data is displayed in white alphanumeric characters for
assisted beats. This data is calculated and displayed on a beat-to-beat basis. Heart Rate
is averaged over two seconds. In addition, a heart-shaped symbol flashes each time the
system detects a trigger point. Physiological data that is displayed includes:
• HR (Heart Rate, in BPM)
• SYS (Systolic Pressure, in mmHg)
• AUG (Augmentation, in mmHg)
• DIA (Diastolic Pressure, in mmHg)
• MAP (Mean Arterial Pressure, in mmHg)
When the Assist ratio is 1:2 or lower, the Unassisted AP values appear continuously in
YELLOW below the Assisted value.
Other operating information displayed includes:
• Balloon Volume (Current set volume. This is automatically set from the IAB
connector or can be changed by the user.)
• HE (remaining helium pressure in the tank, bar graph display in PSI)
• ALARM STATUS (on or off)
• FiberOptix sensor status: A lightbulb is displayed in the AP scaling area. The
™
color of the lightbulb alerts the user as to the current status of the FiberOptix
AP sensor. (See page 3-31 for details).
• Trigger Signal (flashing heart symbol and white highlights on green ECG trace)
• Trigger mode (Displayed under the HR) The color of the trigger mode matches
the associated waveform. Internal trigger is displayed in YELLOW.
• Diagnostics (alphanumeric messages)
• ECG/Source/Lead and Gain State (AUTO or MANUAL)
• Arterial Pressure/Balloon Pressure Waveform Scales
• Operation mode selected: Displayed above the ECG waveform in Yellow and by
LED's on the key.
• Warning messages: These include, Battery Operation, Weaning Selected, Alarms
Off and Operations Mode selected.
• Cursor (magenta)
