CAUTIONS

• Clean, dry, medical grade gas sources supplied at 17 – 55 psi (117 kPa – 380 kPa) unrestricted flow must be used at
all times to assure proper operation of the Crossvent-2i+ Ventilator.
• The Crossvent-2i+ should not be steam or gas sterilized as this will result in damage to some of its components.
• When connecting the pneumotachograph (optional) it is important that the proximal and distal tubes be connected
to the proper connector to assure correct operation. It is also important that the side ports of the flow sensor
head point upward to prevent condensate from collecting in the two pressure tubes. Condensate can cause
improper readings and this in turn can cause possible system malfunction. These tubes should be periodically
inspected and any condensate should be removed.
• Always connect both flow sensor tubes to the ventilator before attaching sensor head to patient circuit to prevent
possible damage to the internal sensing device and also to prevent humidified gas from possibly flowing up the
tubes.
• Never block the patient proximal or patient distal connections or flow sensor head with gas supply connected to the
ventilator as this can possibly damage the flow transducer.
• Connect the oxygen sensor (optional) upstream of the humidifier since the fuel cell functions better in non-
humidified gas.
• Touch screen control keys should be pressed by hand only. Care should be taken not to allow keys to be contacted
by sharp objects as damage may result.
• Clean touch screen only with alcohol. Clean the rest of the Crossvent-2i+ unit with mild, non-abrasive, anti-
bacterial cleanser.
• Do not place liquids on or near the Crossvent-2i+. Liquid entering the unit can cause severe damage and
malfunction.
• It is recommended that the Crossvent-2i+ never be left with its battery discharged as this will reduce battery life.
After discharge of the battery, recharge fully before disconnecting the plug-in power supply.
• Only replace the battery pack with Bio-Med Devices part #PRT2268. Do not substitute. The cells are non-
standard high capacity
• When using an AC power source, only the power supply provided with the Crossvent is approved for use with this
ventilator. Any other power supply may cause damage and/or unreliable operation (See Appendix E).
• Any more comprehensive DC power supply than that which is supplied must be short circuit protected and must
comply with all of the specifications and standards as listed in Section III, Part B.
• Do not use in an MRI room.
• Antistatic or electrically conductive hoses or tubing should not be used.
• When it is necessary to operate the Crossvent from an AC inverter, only inverters in compliance with NEMA
standards should be used (see Appendix E).
• 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.
