ECG Monitoring
Overview
This chapter describes the Efficia DFM100’s basic ECG and arrhythmia monitoring functions. The
device uses Philips’ ST/AR Algorithm for ECG analysis.
You can use the Efficia DFM100 to monitor your patient’s ECG through:
• multifunction electrode pads.
• 3- or 5-lead ECG monitoring electrode sets.
• external paddles (for quick assessment only, not continuous monitoring).
If both pads and monitoring electrodes are connected, the Efficia DFM100 allows you to select a
lead to monitor from either source.
Configurable heart rate and arrhythmia alarms clearly communicate patient status, both audibly and
visually.
You can use the Efficia DFM100 to monitor both adult and infant/child ECGs. Use the Patient
Category button to switch categories.
When pressing the Patient Category button, all parameter alarm limits change to the new patient
category. These changes are retained when you switch modes.
• For patients that are ≥ 25kg or ≥ 8 years old, use Adult patient category.
• For patients <25kg or < 8 years old, use Infant/Child patient category.
ECG waveforms can be acquired through the Therapy port for pads/paddles or the ECG
Monitoring port for 3- or 5-lead sets. When you are using 3-lead ECG monitoring, only one ECG
lead vector is available. If you are using 5-lead ECG monitoring, up to three ECG lead vectors are
available at the same time for display.
WARNINGS: When monitoring neonatal ECGs, inaccurate measurements and alarms could result because of
differences in the characteristics of the adult ECG compared to the neonatal ECG.
When an external pacemaker is being used on a patient, arrhythmia monitoring is severely
compromised due to the high energy level in the pacer pulse. This may result in the arrhythmia
algorithm’s failure to detect pacemaker non-capture or asystole.
During complete heart block or pacemaker failure (to pace or capture) tall P-Waves (greater than 1/5
of the average R-Wave height) may be erroneously counted by the arrhythmia algorithm, resulting in
missed detection of cardiac arrest.
Algorithms in the Efficia DFM100 use the currently set internal Paced Status during rhythm
analysis. If the Paced Status is set to unknown, the algorithm uses Paced. In order to get a more
accurate rhythm analysis, confirm that the patient’s paced status is set correctly.
