WARNING
5 For patients with pacemakers, the pacing impulse analysis function must be switched
ON. Otherwise, the pacing impulse may be counted as regular QRS complexes,
which could prevent an asystole event from being detected.
6 PACEMAKER
PATIENTS
—
Rate meters may continue to count the pacemaker rate
during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon
rate meter alarms. Keep pacemaker patients under close surveillance.
7 The electrodes should be made of the same metal materials.
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 3v/m) specifies that the electrical
field density exceeding 1v/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.
12.3 Monitoring Procedure
12.3.1 Preparation
1.
Prepare the patient's skin prior to placing the electrodes.
The skin is a poor conductor of electricity, therefore preparation of the patient's skin is
important to facilitate good electrode contact to skin.
Shave hair from sites, if necessary.
Wash sites thoroughly with soap and water. (Never use ether or pure alcohol, because
this increases skin impedance).
Rub the skin briskly to increase capillary blood flow in the tissues and remove skin
scurf and grease.
2.
Attach clip or snap to electrodes prior to placement.
3.
Put the electrodes on the patient. Before attaching, apply some conductive jelly on the
electrodes if the electrodes are not electrolyte self-supplied.
4.
Connect the electrode lead to the patient's cable.
5.
Make sure the monitor is ready with power supply.
