ECG Monitoring
WARNING
After attaching the electrode to the
patient and connecting the electrode
lead to the transmitter, check that
electrodes are attached to the patient
and check that the electrode lead is
connected to the transmitter properly.
When the electrodes are removed from
the patient, do not touch the metal part
of the electrode with bare hands or let
the metal part of the electrode contact
the metal part of the bed or any other
conductive parts. Failure to follow this
warning may cause electrical shock or
injury to the patient by discharged
energy.
WARNING
The transmitter detects the pacemaker
pulse and rejects the pacemaker pulse
from the heart rate count. However, all
of the pacemaker pulse might not be
rejected. If the pacemaker pulse is not
rejected, the pacemaker pulse is
detected as QRS and false heart rate
may be indicated. Keep pacemaker
patients under close observation.
* For the pacemaker pulse rejection capability
of ZM-520PA/521PA/530PA/531PA
transmitter refer to the “Specifications -
ECG” section.
WARNING
The pacemaker pulse can be
overlooked or detected as QRS. You
cannot confirm the pacemaker
operation only from the detected
pacemaker pulse.
CAUTION
Only use Nihon Kohden specified
electrodes and electrode leads. When
other type of electrodes or electrode
leads are used, the “CHECK
ELECTRODES” message may be
displayed and ECG monitoring may
stop.
CAUTION
When the “ELECTRODE OFF” or
“CHECK ELECTRODES” message is
displayed on the receiving monitor,
ECG is not monitored properly and the
ECG alarm does not function. Check
the electrode, electrode leads, and if
necessary, replace with new ones.
CAUTION
Hold the connector of the electrode
lead when connecting/disconnecting
the electrode lead. If you disconnect
the electrode lead by pulling the lead, it
damages the electrode lead.
