electromagnetic field can cause momentary degradation of the ultrasound
image. When interference is present or intermittent, use caution when
continuing to use the system. If interference occurs often, review the
environment in which the system is being used, to identify possible sources
of radiated emissions. These emissions could be from other electrical devices
used within the same room or an adjacent room. Communication devices
such as cellular phones and pagers can cause these emissions. The existence
of radio, TV, or microwave transmission equipment located nearby can
cause emissions. In cases where EMI is causing disturbances, it may be
necessary to relocate your system.
• For information on electromagnetic emissions and immunity as it applies
to the system, see "Electromagnetic Compatibility" on page 67. Ensure that
the operating environment of your system meets the conditions specified
in the referenced information. Operating the system in an environment that
does not meet those conditions may degrade system performance.
Debrillators
Observe the following warnings when a defibrillation is required while using the
ultrasound system.
WARNINGS
• Before defibrillation, always remove all patient-applied parts from the patient.
• Before defibrillation, always disconnect invasive transducers from the system.
• A disposable transducer cover provides no protective electrical insulation
against defibrillation.
• A small hole in the outer layer of the transducer opens a conductive path
to grounded metal parts of the transducer. The secondary arcing that could
occur during defibrillation could cause patient burns. The risk of burns is
reduced, but not eliminated, by using an ungrounded defibrillator.
Use defibrillators that do not have grounded patient circuits. To determine
whether a defibrillator patient circuit is grounded, see the defibrillator service
guide, or consult a biomedical engineer.
