48. AUG. ALARM
Indicates diastolic augmentation alarm limit in mmHg. If the alarm is not
enabled, OFF is displaved.
49. BATTERY INDICATOR
Indicates the charge remaining in the internal batteries. This indicator 1s
displayed only when the system is operating off of che internal batteries.
Display of the "Low Battery" advisory message indicates less than 30 minutes
of remaining battery life. When this message appears the battery symbol is
displayed as empty and starts flashing. Connect the pump to AC power and
turn the AC mains switch on as soon as possible.
50. HELIUM INDICATOR
Approximately indicates the amount of helium remaining in the tank. A
"Low Helium" advisory message will be displayed when the rank is almost
empty.
51. ECG Scale |
The ECG scale is located immediately to the left of the displayed ECG
wavetorm. It is provided to facilitate determination of ECG amplitude. The
scale is one centimeter high. The annotation indicates the current scale factor
for the displayed ECG waveform, e.g. 1 mv/cm.
NOTE: The displayed ECG signal is automatically scaled (amplified) for
optimal screen presentation. Due to the automatic scaling, low ECG
amplitudes may appear to be of normal amplitude when displayed.
Judgements concerning ECG amplitude should be done with reference to
the annotated scale or a printed ECG output.
Arterial Pressure (AP) Scale
The AP scale is located immediately to the left of the displayed AP
waveform. The scale is a vertical line with annotated "tick" marks. The units
of the annotation are mmHg. The scale is provided to facilitate determination
of AP amplitude.
NOTE: The dispiayed AP signal can be automatically or manually scaled
(amplified) and offset for optimal screen presentation (See section 1.3.22.1
for more information). When using automatic scaling, low AP amplitudes
may appear to be of normal amplitude when displayed. Judgements
concerning automatically scaled AP waveforms should be done with
reference to the annotated scale, patient arterial pressure parameter display,
ога printed AP output.
Wavetorms (ECG, AP, shuttle gas )
Depending upon user preferences, the system displays either two waveforms
(ECG and AP) or three waveforms (ECG,AP, Balloon Pressure). Order of
display is fixed, ECG is displayed horizontally across the top of the screen.
Next, Arterial Pressure is displayed across the middle of the screen and
finally, across the bottom, the balloon pressure waveform (if enabled). If the
balloon pressure waveform is not enabled, then the additional screen area is
used by the arterial pressure waveform display.
