● DO NOT tape, obstruct or remove the reed alarm during clinical use.
● DO NOT occlude the sensor port on the side of the Bird Sentry blender.
● Do not routinely disconnect or remove O
must be disconnected, the full "warm-up" period, as stated in the sensor specifications, may be
required after the sensor is reconnected.
● The mixed gas bleed continuously bleeds to atmosphere at the oxygen concentration setting of
the control knob. Bleeding oxygen into any closed area could increase the risk of fire or
explosion. Do not operate this device in the presence of any flame or source of ignition; or
when using devices such as electrosurgical equipment or defibrillators.
Cautions
● Do not attempt to clean the Bird Sentry blender with cleaning agents that contain phenols,
ammonia chloride, or chloride compounds, or that contain more than 2% glutaraldehyde.
These agents may damage the plastic components and control panel overlays.
● Dropping or severely jarring the sensor after calibration may shift the calibration point enough
to require recalibration.
● Using the Bird Sentry blender to analyze and monitor oxygen concentrations other than at the
sensor port of the unit will require recalibration of the sensor.
● Always operate the Bird Sentry blender with clean, dry medical grade gases. Contaminates or
moisture can cause defective operation. Oxygen should have a minimum dew point of -80°F (-
62°C) or moisture content less than 7.9 PPM (0.0059mg/L). Oxygen "purity" should be at least
99.6% and air used should be medical grade. Water vapor content must not exceed a dew
point of 5°F (3°C) below the lowest ambient temperature to which the delivery system is
exposed. Particulate content must not exceed that which would be found immediately
downstream of a 15 micron absolute filter. Refer to CGA commodity specifications G-4.3 and
G7.1 for more information. Water vapor content of medical air or 0, supply to the blender must
not exceed 5.63 x 103 milligrams H2O per cubic meter of non-condensable gas.
● When disassembling, care must be exercised to prevent damaging the printed circuit board. All
work must be accomplished in a static safe environment.
● This device has not been tested in the presence of gases other than air or oxygen.
Notes
● The Bird Sentry blender is tested for compliance with ISO 11195:1995, clause 6, and meets
requirements regarding reverse gas flow as delivered.
● Applicable parts used in the Bird Sentry blender have been cleaned and degreased for oxygen
service. Any lubricants used are designed specifically for the application. Do not use anything
other than CareFusion specified lubricants when servicing the Bird Sentry blender.
● As long as the total pressure of the gas mixture being monitored is constant, the Bird Sentry
blender will accurately read oxygen concentrations. However, if the total pressure varies the
reading will fluctuate proportionately as the sensor actually measures the partial pressure of
oxygen in the mixture. The sensor readings will also change proportionately with barometric
pressure changes. Because of this, daily calibration of the sensor is recommended.
