Patient Monitor User Manual
6 If the ECG signal exceeds the measuring range, the monitor will indicates it by a
message "ECG Signal Exceeded".
7 In order to avoid being burnt, please keep the electrodes far away from the radio knife
while using electrosurgical equipment.
8 When using Electrosurgery (ES) equipment, do not place an electrode near the
grounding plate of the Electrosurgery device, otherwise there will be a great deal of
interference with the ECG signal.
9 The electrodes should be made of the same metal materials.
10 ECG cables can be damaged when connected to a patient during defibrillation or
using other high frequency equipment. Check cables for functionality before using
them again. It is recommended to use defibrillator-proof ECG lead to avoid burn.
11 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
