down independent of the On/Off switch. If this occurs, the external power supply must be used to recharge the battery and
the On/Off switch must be turned to Off and then back to On before the unit will operate.
NOTE: 20 minutes of operation after the low battery alarm assumes a properly maintained battery in
good condition.
To prolong life and maintain performance, it is recommended that the Crossvent be stored with the power supply plugged in
or with the battery fully charged at a relative humidity of 65% (±20%) whenever possible. Because NiMH batteries will
naturally "self-discharge", it is strongly recommended the battery be cycled through at least one charge/discharge according
to the table below if left off the power supply for an extended period of time.
WARNING: Never operate the CROSSVENT without a battery since it will fail to
operate if the plug-in power supply is removed.
CAUTION: The battery should be placed at least every two years. Only use batteries
supplied by Bio-Med Devices, part #PRT2268. Do not substitute.
CAUTION: Do not allow the temperature of the battery to go above 131° F (55° C)
whether the unit is on or off as this may cause damage resulting in a shorter life expectancy
of the battery.

The main patient circuit corrugated hose is attached here. It provides the un-humidified breathing gas to the patient circuit.

Provides the pressure signal to operate the exhalation valve. During inspiration it applies a high-pressure signal to the
exhalation valve diaphragm, which sets the PIP Limit. During expiration it provides a zero or PEEP level to the exhalation
valve diaphragm.

Provides connection of the proximal airway pressure tube to the internal pressure transducer. This allows the Crossvent-
2i+ to monitor airway pressure.

These two connectors provide the pressure signals to the internal transducer that permits the measurement of flow which is
used to display Exhaled Tidal Volume as well as sense effort for Flow Trigger. The proximal connector should be
connected to the tube on the pneumotachograph (PNEUMOTACH) which is proximal to the patient. The distal connector
is connected to the tube that is more distant from the patient. The pneumotach is attached via its two tubes to these
connectors. Flow is measured as the differential pressure across the orifice of the pneumotach.
WARNING: The pneumotach must be in the circuit and connected to the ventilator
when using Flow Triggering. If the pneumotach is not being used, then Constant
Flow should be the ventilator mode.
CAUTION: The pressure connection tubes of the pneumotach should always be mounted
vertically to prevent collection of condensate in the pressure tubes. The tubes should be
inspected periodically and condensate should be removed. This condensate may cause
erroneous readings and thus improper operation of the Crossvent-2i+. Never block these
connections with the unit operating as this can damage the internal transducer. Always
securely connect both pneumotach lines (proximal and distal) to their respective connectors
before inserting the pneumotach in the flow stream. This will prevent possible damage to
the internal transducer and will also prevent humidified gas from inadvertently blowing up
the pneumotach sensing lines.
