More Information

  • Select Your Options (not included):
    nVISION Data Management Software: Windows based software provides seamless transfer of stored data for further analysis, report generation and storage (8500M)
    - Serial to USB adapter for data transfer (Standard FTDI or Continua compliant PHDC protocol options)
  • SpO2 Display:
    The SpO2 display is identified by the SpO2 symbol. This 3-digit light-emitting diode (LED) display shows the current oxygen saturation percentage.
  • Pulse Rate Display:
    The Pulse Rate display is identified by the symbol. This 3-digit LED display shows the pulse rate in pulses per minute.
  • Pulse Quality Indicator:
    The Pulse Quality Indicator display (identified by the symbol) is a tricolor LED that blinks once for each detected pulse. The color of the Pulse Quality indicator changes with the pulse strength signal, as described below.
    - Green indicates a good pulse strength signal.
    - Amber indicates a marginal pulse strength signal. To improve signal quality, reposition the sensor, try a different sensor type, reduce patient movement, or improve the site circulation.
    - Red indicates an inadequate pulse strength signal. While the Pulse Quality display is red, SpO2 and pulse rate values are not updated. After about 10 seconds, the values are replaced with dashes, indicating that readings are not possible.
  • Low Battery Indicator:
    When battery capacity is low, the display will blink once each second. If the batteries are not replaced, they will reach critically low capacity and the display will blink dashes. The Pulse Quality LED will blink red or amber, not green. After 10 minutes of critically low battery capacity, the display will go blank.
  • Sensor Fault or Inadequate Signal Display:
    If the device determines that a sensor fault or inadequate signal condition exists (a sensor disconnect, failure, misalignment or incompatibility with the monitor) or if a pulse oximeter sensor signal is no longer detected, a dash (-) appears in the leftmost position of the SpO2 display. The readings that are displayed will freeze for 10 seconds if the pulse oximeter sensor fault or the inadequate signal continues.
