280 bpm with a default setting of 150 bpm. When the
unit is monitoring a patient's heart rate through pulse
oximetry (SpO
), however, the unit automatically lowers
2
the upper limit for the high heart rate alarm to 235 bpm.
The unit restores the original high heart rate alarm limit
when ECG monitoring resumes.
Suspending and Silencing Alarms
When a high priority alarm occurs, the unit emits a
continuous alarm tone, highlights the value of the
alarming parameter on the display screen, and flashes
the alarm symbol associated with that parameter.
You can either suspend the alarm tone for 90 seconds or
you can silence the alarm tone.
Suspending Alarm Tones
To suspend the alarm tone for 90 seconds,
press and release the ALARM SUSPEND
button in less than 1 second. The alarm tone
stops, the unit displays an "X" across the
alarm's flashing alarm symbol, and the value of the
alarming parameter remains highlighted. (If you press
the ALARM SUSPEND button again, alarm processing
is reactivated.)
After 90 seconds, if the physiological
parameter remains at a value that triggers the
alarm, the unit sounds the alarm tone again.
If the alarm condition clears (the physiological
parameter returns to a value within range) after you have
suspended the alarm tone, the unit resets the alarm and
displays the alarm symbol (no flashing, no "X"). The
alarm parameter displays normally (no highlighting).
If a second, different alarm occurs after you suspend an
alarm tone, you can suspend the alarm tone for that
second parameter by pressing and releasing the
ALARM SUSPEND button. The unit performs the same
way as described previously for the first alarm.
Silencing Alarm Tones
To silence the alarm tone, press and hold down
the ALARM SUSPEND button for between 1
and 3 seconds (hold down button for at least
one second, but less than 3 seconds). The
alarm tone stops, the unit displays the alarm's alarm
symbol with a dashed line "X" across it, and the value of
the alarm parameter remains highlighted. (If you press
the ALARM SUSPEND button again, alarm processing
is reactivated.)
The alarm tone does not sound again as long
as the physiological parameter's value remains
out of range.
If the alarm condition clears (the physiological
parameter returns to a value within range) after you
silence the alarm tone, the unit resets the alarm and
displays the alarm symbol (no inverse video, no "X").
The alarm parameter value displays normally (no
highlighting).
10-4
After the unit resets an alarm, should the
physiological parameter again go out of range,
it triggers the alarm.
Deactivating and Activating Alarms
To deactivate all alarms on the E Series unit, press and
hold down the ALARM SUSPEND button for 3 seconds
or longer. The alarm symbol for all alarms has an "X"
through them to indicate that the alarms are deactivated.
Alarm parameter values display normally (no
highlighting).
To reactivate the alarms, press and release the ALARM
SUSPEND button in less than 1 second.
Smart Alarms
In Defib, Monitor or ON mode, ECG/heart rate alarm
capabilities are enhanced with the defibrillation advisory
feature called Smart Alarms. When alarms are
operating, this feature triggers an audible alarm
whenever the unit detects ventricular fibrillation or wide
complex ventricular tachycardias. For advisory-triggered
alarms, an additional CHECK PATIENT message
appears on the display and the chart recorder print out.
If alarms are operating in Pacer mode (Pacer version
only), the unit displays the message VF ALARMS OFF
indicating that the Smart Alarms feature has been
disabled.
Recorder Operation
The stripchart recorder documents the ECG trace with a
6 second delay at all times. To start the stripchart
recorder, press the RECORDER button. The stripchart
recorder runs continuously until you press the button
again.
Each time the strip recorder is started, the time, date,
ECG lead, size, and heart rate are printed on the top part
of the paper. If the unit is pacing, the output current is
also printed. Similarly, if the defibrillator has been
discharged, the delivered energy is printed.
Note: Check the paper supply at the beginning of each
shift and after each use to ensure adequate
recording capability. A colored stripe on the paper
means that the paper supply is low.
A CHECK RECORDER message appears on the display
when the stripchart recorder is activated without paper.
The stripchart recorder automatically shuts off when
there is no paper.
After loading new paper, press the RECORDER button
to start the strip recorder.
Diagnostic Bandwidth
When using an ECG cable for monitoring, you can
switch the unit to diagnostic bandwidth (0.05-150 Hz) by
pressing and holding the RECORDER button depressed.
Diagnostic bandwidth is maintained as long as the
RECORDER button is held down. The unit reverts to
9650-1210-01 Rev. T
