According to AAMI specifications the peak of the synchronized defibrillator discharge
should be delivered within 60 ms of the peak of the R wave. The synchronization
pulse output on the patient monitors is delayed by a maximum of 35 ms from the R
wave peak. Your biomedical engineer should verify that your ECG/Defibrillator
combination does not exceed the recommended maximum delay of 60 ms.
12
Before outputting signals with defibrillator synchronization or ECG, check if the output
is functioning normally.
13
ECG accessories are not suitable for DIRECT CARDIAC APPLICATION. (Refer to
IEC60601-1 for more information about the definition of DIRECT CARDIAC
APPLICATION.)
14
Line isolation monitor transients may resemble actual cardiac waveforms and thus
inhibit heart rate alarms. When the electrode or lead is loose or fallen, the monitor is
easily affected by the transient response of certain types of insulation monitors. The
transient monitor signal produced by poor insulation of the line may be very similar to
the actual heart waveform, which will prevent the monitor from prompting a heart rate
alarm. In order to avoid this, user should check lead wires for damage and ensure
good skin contact prior to and during use. Always use fresh electrodes and follow
proper skin preparation techniques.
15
The monitor can only be used on one patient at a time. Monitoring more than one
patient simultaneously may result in hazards to the patient.
16
Pacemaker Failure: During a complete cardiac block or when pacemaker is unable to
pacing/capture, high P-wave (greater than 1/5 of the average height of the R-wave)
may be incorrectly counted by the monitor, which leads to a missing asystole.
NOTE:
1
Interference from a non-grounded instrument near the patient and ESU interference
can cause inaccuracy of the waveform.
2
IEC/EN60601-1-2 (protection against radiation is 3 v/m) specifies that the electrical
field density exceeding 3 v/m may cause measurement error in various frequencies. It
is accordingly suggested that do not use equipment generating electrical radiation
near ECG/RESP monitoring devices.
3
If the pacemaker signals are beyond the claimed range, the heart rate may be
calculated incorrectly.
4
In the default settings of the monitor, the ECG waveforms are the first two waveforms
from top in the waveform area.
5
For measurements in or near the heart we recommend connecting the monitor to the
potential equalization system.
6
For protecting environment, the used electrodes must be recycled or disposed of
properly.
