ECG MONITORING
This section describes the basic ECG monitoring functions of the Responder 2000.
The Responder 2000 can be used for ECG monitoring. The monitoring function allows the operator to monitor through:
•
Pads
•
3-lead ECG Electrodes
•
5-lead ECG Electrodes
If both pads and monitoring electrodes are connected, monitoring allows you to select a lead from the 3-lead, 5-lead ECG
source, or to monitor through the pads.
Configurable heart rate and arrhythmia alarms clearly communicate patient status, both audibly and visually.
See Setting the ECG Source and Gain in this section for changing these settings.
ACTIVATING AND DEACTIVATING FILTERS
Activating muscle and AC line filters makes the displayed ECG insensitive to AC interference and muscle tremor.
However, the filters alter the ECG signal, and a filtered signal is not suitable for diagnosis (displayed or printed ECG).
NOTE:
Active filters will alter the ECG signal. Switch off the filters to obtain a diagnostic ECG.
NOTE:
ECG signals acquired with pads, paddles, or spoons cannot be used for diagnostic purposes.
MONITORING HEART RATE
WARNING:
No Asystole Alarm
The defibrillator gives asystole alarm only when the heart rate falls below the low HR limit. Therefore, do not disable the
low HR limit.
WARNING:
Incorrect HR / No HR Alarm
In the presence of arrhythmias and morphological changes of the ECG, the device may not be able to calculate the
correct heart rate. Beats may be counted twice or may be ignored
NOTE:
The defibrillator can be set up to automatically activate the alarm tone on power up. The default alarm
limits can also be adjusted in the setup menu.
During patient transport the device may fail to identify arrhythmias due to motion artifact.
The default heart limits are 40 and 180 bpm and the audio alarm is disabled. The audio alarm can be enabled
permanently from the setup menu.
The defibrillator reports an alarm condition if the HR exceeds one of the alarm limits for more than 10 seconds:
•
The audio alarm sounds (configurable)
•
The recorder starts (configurable)
•
The alarm is indicated on the display
When the parameter reading returns to normal range, the audio alarm stops.
For information on setting and changing alarm parameters, refer to chapter
Responding to Alarm

Heart Rate Alarm Limits
