Troubleshooting
2001989-200E ApexPro™ D-5
Pace 2 mode analyzes waveforms with the added capability of minimizing the
chance of counting severe residual pacemaker energy as QRS complexes. In
relation to the event rejection capability of Pace 2 pace mode, certain
morphologies may not be detected. Arrhythmia calls like asystole or pause may
be made with heart rate identified as less than actual.
Again, pacemaker patients should be kept UNDER CLOSE OBSERVATION. The
appropriate pace mode may be determined at the time the pacemaker patient is
admitted to the monitoring system. The Pace 2 mode is recommended for use
whenever possible.
Check ECG signal from patient:
1. Check/adjust lead placement.
2. Check/perform skin preparation.
3. Check/replace electrodes.
ST troubleshooting
Problem: ST numerics changed to Xs
Solution: An ST value changes to Xs when the patient’s dominant morphology has
not been detected 16 times in the last 30 seconds. The program waits one minute and
then automatically relearns. ST numerics will be displayed after the relearn.
IF PROBLEM CONTINUES:
1. Check for morphology change.
2. Check for noise on ECG.
3. Relearn:
a. Click on the patient’s ECG tab.
b. Click on the Relearn button.
SpO2 messages
WARNING
LOSS OF ALARMS—Do not use transmitter accessory devices
such as SpO2 and NBP without ECG cables attached. Failure to use
accessory devices in the prescribed manner may result in a loss of
alarms.
NOTE
The Xpod oximeter can display the same SpO2 system status messages as the
Apex oximeter, except for the CHANGE BATTERY message. For the Xpod
oximeter CHANGE BATTERY message, refer to Transmitter-related messages
on page D-10. The Xpod oximeter uses the battery power supplied by the
transmitter and therefore does not support this message.
