•
Extreme care should be taken to assure that the patient circuit components are connected
correctly. Improper connection can cause malfunction.
•
Periodically the CROSSVENT-3+ should be operated in the test mode to ascertain that it is
functioning properly. A test lung should be ventilated prior to each use to further insure that all
modes are functioning correctly. An external spirometer should be used to verify correct volumes
and flow rates.
•
The patient should never be left unattended after the ALARM QUIET key is depressed since this is
followed by a period when the audible alarms are deactivated.
•
An audible alarm always indicates an anomalous state which should always be rectified.
•
While some alarms may be turned off to permit use of the CROSSVENT without them, it is
recommended that they be used at all times.
•
Always be certain that the Maximum Pressure Limit is set correctly and is operative even when
volume limiting, to prevent possible inadvertent administration of high pressure.
pressure can be caused by blocked tubes, changes in patient compliance or resistance, or system
malfunction.
•
The alarm ports on the front of the CROSSVENT should never be obstructed.
•
For proper operation only the O
•
Never operate the CROSSVENT-3+ without a battery since it will fail to operate if the plug-in
power supply is removed.
•
The screened ports on the side, back, and bottom of the unit should not be obstructed when the
ventilator is in use.
•
Only qualified, trained, service technicians should attempt repairs and service when needed.
Serious personal injury and/or equipment damage can result if repairs are performed by unqualified
personnel
•
It is imperative to verify that clinically appropriate alarm limits are fully operational following
connection of the ventilator to a patient.
•
It is important to note that once a sensor has been turned off, the alarms for that sensor are
inoperative.
•
Breathing through the negative pressure relief valve requires a greatly increased work of breathing
and only air is provided. A situation in which the patient is breathing through this valve should be
rectified immediately in order to prevent possible adverse affects to the patient.
•
It is extremely important that the Pressure Trigger control be carefully adjusted to assure proper
operation in the CPAP mode.
• When in SIMV, it is important to always set a correct SIMV RATE, TIDAL VOLUME and FLOW
to insure proper ventilation in case the patient becomes apneic.
• When in CPAP, it is important to always set a correct BACKUP RATE, TIDAL VOLUME and
FLOW to insure proper ventilation in case the patient becomes apneic.
• To obtain the full 3-minute duration of the Power Failure alarm, the Crossvent must have been
powered on for at least 1 minute.
• All safety measures must be observed when servicing this device. In particular, the ventilator must
be turned off and the power supply disconnected.
• Bio-Med Devices cannot be held responsible for any failure to adhere to the recommendations set
