Patient Preparation for ECG Monitoring
The following tips provide optimal ECG monitoring
results, but must never replace hospital-approved
practices or manufacturer’s recommendations.
Follow hospital procedures for proper skin
preparation. Dräger recommends Ag/AgCl
disposable electrodes. Never use disposable
electrodes after their expiration date and make sure
that there is enough gel and that the gel has not
dried out.
P- and T-waves with amplitudes exceeding 0.2 mV
can be interpreted as QRS complexes. To allow
detection of low heart rate conditions under these
circumstances, place the lead with the highest R-
wave in channel ECG1. If P- and T-waves continue
to be misinterpreted, reposition the electrodes or
use a pulse oximeter to monitor the pulse rate.
To maintain a clear signal, change electrodes every
24 to 48 hours or more often when the following
occurs:
– ECG signal degradation
– Excessive patient perspiration
– Skin irritation
The illustrations starting on page 140 show various
ECG-electrode configurations. Consider the
following when selecting the electrode sites:
– Surgery – keep electrodes as far from the
surgical site as possible, while maintaining a
clinically useful lead configuration. Place the
cable and lead wires as far from the ESU as
possible and perpendicular to the ESU cables.
– Burn Patients – use sterile electrodes. Clean
the equipment thoroughly and follow hospital
infection control procedures.
Electrosurgery
The integrated ESU suppression can improve the
performance of the monitor during electrosurgery,
reduces noise on ECG waveforms, and protects
the patient from burns.
To minimise interference from the
electrosurgical unit
1 Select the HR parameter box.
or
Select Sensor parameters... from the main-
menu bar > ECG tab > Settings 2 tab.
2 Select
ESU next to the Filter selection.
NOTE
12-lead monitoring is not available when the ESU
filter is enabled. Likewise, the ESU filter selection
is not available when you are using 12-lead
monitoring.
