EMS Environment
While the DFM100 has been designed for use in the EMS environment, use in these conditions can
put stresses on the device and its accessories that could potentially affect essential performance. Users
in these environments should be aware of the following:
• Direct sunlight and other sources of excessive illumination can affect SpO
2
readings. For more
information see “Understanding Pulse Oximetry” on page 110.
• The device has been built to withstand lint and dust. After an event where the DFM100 was
exposed to lint and dust, you should thoroughly clean it. See “Cleaning Instructions” on
page 177 for more information.
• Cellular telephones, 2-way radios and other radio frequency-emitting devices could cause
interference problems and potentially affect the behavior of the device. Users should abide by
the recommended separation distances found on page 218.
• Check all accessories frequently. Confirm that all sensors, electrodes, ports and the Therapy
cable are in working order. Replace all that are not in good working order.
• Make sure that the Therapy Cable Collar is installed on devices in high-vibration environments.
See “Therapy Cable Collar” on page 19.
• Devices in the EMS environment may require a power converter to convert vehicle DC power
to AC power for the Efficia DFM100.
