• Because this is a CE marked device, it must never be modified without prior expressed written
consent from Bio-Med Devices.
• When setting Pressure Trigger, auto-triggering or missed breaths may occur due to various
conditions including, but not limited to, compliance, resistance, rate, flow, PEEP, I:E ratio, and
circuit characteristics.
• Do not re-use disposable breathing circuits.
• Operation of the Crossvent in a contaminated environment can be hazardous when entrainment is
used.
• It is extremely important that the Pressure Trigger control be carefully adjusted to assure proper
operation in the SIMV and CPAP modes. Also, under certain conditions in SIMV with PEEP,
even though the low peak pressure alarm is set correctly for assisted breaths, there may be no low
peak pressure alarm following a patient disconnect until the next assisted breath. This period may
be up to 2 minutes.
• Improper changes made in the Calibration menu can be detrimental to the performance of the
ventilator.
• Do not apply tension to the flow sensor (pneumotach) tubing. Do not allow the sensor to be in the
patient circuit when not connected to the ventilator.
• In rare instances, when using the Crossvent with an air/oxygen blender, there may be a reduction in
the delivered flow at the higher flow settings. This reduction may occur when the blender is set
below 30% or above 90% O
pressures to the blender will tend to decrease the flow further so be sure these supply pressures are
maintained at 45- 75 PSI (310-517 kPa). If the Crossvent has the exhaled tidal volume monitoring
feature, it is recommended this be used to ensure proper tidal volumes are being delivered. If it
does not have this feature, then an external spirometer is recommended.
