Stimulation intensity setting

After switching the PRIMEDIC
independent of the chosen operation mode or frequency.
The stimulation intensity can be adjusted by the keys Pacer-Intensity + and Pacer-
Intensity - . The alteration occurs with each key press in steps of 5
downwards. The stimulation frequency can also be altered during pacing.
If the keys Pacer-Intensity + or - are pressed continuously, the frequency is stepped
each half second. If the key is released, the frequency remains at the last adjusted
value.
If one of the pacer intensity keys + or – is depressed for an extended period of time,
the current level is changed by an increment of 5 every half second. The value last set
remains if the key is released.
The magnitude of the stimulation intensity is dependent of the physical condition of
the patient. The current intensity should be adjusted in a way that its effect can be
seen in the ECG monitored.
The magnitude of the intensity is a compromise between a good and effective stimu-
lation of the heart and an eventually necessary sedation of the patient. If the stimula-
tion effects are clearly visible in the ECG, by carefully degreasing the intensity the op-
timal intensity might be adjusted.
Pacing goes along with the contraction of skeletal muscles. This is not an indication
for effective heart stimulation. Always monitor the patients ECG to evaluate a suffi-
cient pacing intensity.

Start And Stop Pacing

The operation mode of the PRIMEDIC
started. During pacing a change of the operation mode is not possible. The set opera-
tion mode is displayed in the monitor.
By pressing the key Stimulation Start/Stop, stimulation starts with the pre-set pa-
rameters. This is acknowledged, with an acoustic signal. The operation mode indica-
tion text in the monitor flashes. With each pacing impulse, the Pacing-LED flashes.
To stop the stimulation press the key Stimulation Start/Stop for a short time, which is
acknowledged by an acoustical signal. The indication text in the monitor stops flash-
ing.
Limited stimulation duration in the OVERDRIVE-Mode:
To prevent a harmful excessive stimulation in the OVERDRIVE-Mode, the stimulation
period without any user adjustments is limited to 15 seconds.
After starting the stimulation with the key Stimulation Start/Stop the stimulation is
started with the pre-set values. The stimulation terminates after 15 seconds if no al-
teration of the Pacer Intensity or Frequency occurred by pressing one of the keys. Af-
ter pressing any key, the 15 seconds timing is restarted.
The stimulation can be stopped anytime before the 15 seconds are elapsed by shortly
pressing the key Stimulation Start/Stop.
During pacing the frequency and the intensity can be altered.
During pacing the heart rate alarms might be used for additional patient surveillance.
Due to the risk of electrocution the conductive surfaces of the electrodes and the pa-
tient might not be touched during stimulation. After treatment the adhesive elec-
trodes need to be removed from the patient. Ensure that conductive surfaces of the
electrodes might not be touched or get in contact with conductive parts or wet sur-
faces and the SavePads Plus cable is not connected to the device anymore.
