Problem
How does the IntelliRate algorithm impact an
Asystole alarm with a QRS waveform?
Why is the monitor calling V Tach when the patient is
not in V Tach?
2094480-001
Solution
switch to single lead analysis so all arrhythmia
interpretations are based on this single ECG lead.
IntelliRate will report Asystole when the following
conditions are met:
The ECG HR has been valid and stable during the
●
previous 30 seconds.
The invasive pressure pulse rate was valid earlier,
●
but does not indicate beat detections in the
previous 30 seconds.
The mean arterial blood pressure of the
●
invasive pressure pulse rate source is below the
user-selected limit.
The SpO parameter if available does not indicate
●
2
beat detections in the previous 30 seconds.
NOTE
The monitoring system may be detecting a wider
QRS complex or artifact in some of the analyzed ECG
waveforms. In addition, the V leads may be exhibiting
polarity changes, which may occasionally cause an
inaccurate call.
1. Assess the patient.
2. Check the ECG signal acquired from the patient.
View each ECG lead to assess the width of the
●
QRS complexes in the analyzed leads.
If artifact exists in any of the analyzed leads,
●
reprep the patient's skin, replace electrodes,
and adjust the electrode placement.
It may be beneficial to move V lead electrodes
●
(chest lead) to alternate precordial electrode
placements to improve detection.
3. Relearn the ECG rhythm. It is important to relearn
the patient's ECG pattern any time the electrode
configuration is adjusted.
If the problem continues, determine the lead with
the narrowest QRS complex, display that lead, then
switch to single lead analysis so all arrhythmia
interpretations are based on this single ECG lead.
CARESCAPE ONE
IntelliRate performs this
analysis only when
pacemaker detection is
configured on.
