ECG Alarm
The range of adjustment of the ECG Alarm is from 30
–
300 beats per minute [bpm]. The lower
alarm limit can be selected in the range 30
–
99 beats per minute. The upper alarm limit cannot
be lower than the lower limit and the value selected can be up to 300 beats per minute. The
lower and upper alarm limits are displayed on the monitor. Changes can only be made in the
Setup menu. When one of the set limits is attained an ECG Alarm is initiated. If no valid heart
rate can be obtained (e.g. on the occurrence of an asystole (cardiac arrest) an alarm is
likewise initiated. In this case the heart rate is indicated in the form of dashes.
The Alarm in the event of an asystole (cardiac arrest) and on exceeding the set ECG limits
takes the form of a loud tone, alternating quickly between 2 pitch levels of approx. 5 seconds
duration. This alarm is repeated every 20 seconds. At the same time a bell symbol and the
heart rate flash on the display.
The ECG Alarm button is used to acknowledge the ECG Alarm. The acoustic Alarm is
suppressed for the duration of one minute. During this period of time the bell symbol on the
display is crossed out. Pressing the button again during this period reactivates the Alarm. The
alarm limits are retained.
The ECG Alarm can be deactivated in the Setup menu. When the ECG Alarm (= 0 %) is
deactivated the bell symbol is permanently crossed out. If in this case the alarm limits are
exceeded no acoustic alarm is initiated, but the bell symbol and heart rate flash, in order to
inform the user.
Note: If the equipment is operated with PRIMEDIC™ SavePads Connect
-Electrodes on the
patient, in auto mode the bell symbol for the ECG Alarm is always crossed out, in order to
indicate that in this condition no ECG Alarm occurs. By this means interfering messages are
avoided during the repetition of the HLW request.
7.5.2
VF Alarm
The VF Alarm only occurs during ECG monitoring with ECG electrodes / ECG cable, by means
of which shocks cannot be applied. With the VF Alarm eight "gong-type" muffled tones are
heard over a period of approx. 5 seconds, which are repeated every 20 seconds and
accompanied by the verbal message
< Analysis recommended, use SavePads >.
If the ECG Alarm is activated, the acoustic Alarm takes place with the ECG Alarm tone. The
speech output is always provided.
The VF Alarm requires, that the ECG cable and the ECG electrodes are replaced by the
PRIMEDIC™ SavePads Connect
-Cable with SavePads Connect defibrillation electrodes, or
otherwise no defibrillation can take place. Whilst defibrillation can take place via the paddles
parallel to the ECG electrodes in the manual mode, in the Auto mode defibrillation is only
possible via SavePads Connect-Electrodes.
The VF Alarm cannot be suppressed by the Mute button.
