Transmitter Channel Management
WARNING
The following actions must be taken to properly receive the transmitter signal of the
correct patient on the receiving instrument. Otherwise, there may be signal loss or
signals may mix causing a serious accident, such as monitoring a different patient.
• Assign a channel administrator in the hospital and only he or she should manage
channel assignment.
• The channel administrator must manage the channels in the facility so that there is
no signal interference.
• When the transmitter channel is changed, the channel administrator must check
that the channel on the receiving monitor is also changed and the signal is
properly received.
• The channel administrator must replace the channel number label on the
transmitter with the new one after changing the channel.
For Patients Using Implantable Pacemaker
WARNING
Interaction Between Minute Ventilation Rate-Adaptive Pacemakers and Cardiac
Monitoring and Diagnostic Equipment*
The bioelectric impedance measurement sensor of a minute ventilation rate-adaptive
implantable pacemaker may be affected by transmitter which is connected to the
same patient. If this occurs, the pacemaker may pace at its maximum rate and the
transmitter may give incorrect data to the monitor. If this occurs, disconnect the
electrode leads from the patient or change the setting on the pacemaker by referring
to the pacemaker’s manual. For more details, contact your pacemaker representative
or Nihon Kohden representative.
* Minute ventilation is sensed in rate-adaptive pacemakers by a technology known as bioelectric
impedance measurement (BIM). Many medical devices in addition to pacemakers use this
technology. When one of these devices is used on a patient with an active, minute ventilation
rate-adaptive pacemaker, the pacemaker may erroneously interpret the mixture of BIM signals
created in the patient, resulting in an elevated pacing rate.
