 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
Below is a list of system status alarm messages that may be displayed in the patient’s
bed window during monitoring. SpO2 messages appear in abbreviated form in graph
headers. If you are unable to resume SpO2 monitoring, contact your sales/service
representative.
NOTE
The Xpod oximeter can display the same SpO2 system status messages as the
Apex oximeter, except for the CHANGE BATTERY message. The Xpod
oximeter uses the battery power supplied by the transmitter and therefore does
not support this message.
