1 Safety Instructions
At all times, strictly follow this manual. The safe use of the FLIGHT 50
Ventilator requires full understanding of its operation, and adherence to the
manual's instructions. The equipment is only to be used for the purpose
specified in section 1.1. Observe all of the WARNINGS and CAUTIONS
posted in this manual, and on buttons found on the FLIGHT 50 Ventilator
and associated accessories.
1.1 General Warnings
External power connection: To maintain grounding
integrity when using AC power, only connect to hospital
grade receptacles. Always disconnect the external power
supply prior to servicing. There is a risk of explosion if
used in the presence of flammable anesthetics.
All settings and adjustments in the different ventilation
modes must be made in accordance with a physician's
prescribed therapy.
Do not use electrically conductive patient circuits.
Always use a clean, disinfected patient circuit.
Always use an outlet filter or equivalent at the Airway
Pressure Connector, to protect the internal transducers
from moisture and other contaminants.
The ventilator is ready for operation only when:
It is completely assembled.
The OVP has been successfully completed.
Failure to identify and correct alarm violations may result
in patient injury.

Safety Instructions
General Warnings
Operator's Manual | 1-2
Ensure that the oxygen source is not empty before and
during the use of the optional Air/Oxygen Entrainment
Mixer or Oxygen Blending Bag Kit.
As Li-Ion batteries are charged and discharged over time,
their ability to hold a charge is decreased with use. This
can shorten the amount of time the ventilator can
function while on battery power.
The batteries should be replaced when they no longer
meet the needs of the user. This depends on a number of
factors including settings and usage patterns.
Charge the batteries for a minimum of three hours before
powering the ventilator from the batteries. This ensures
that the batteries will be fully charged.
During storage, charge the batteries for a minimum of
three hours every 30 days. This improves the chances of
always having charged batteries.
Always ensure that the green Ext. Power LED is
illuminated after connecting the FLIGHT 50 Ventilator to
an external AC or DC power source. If the LED is not
illuminated, check all power connections and resolve any
problems.
Always plug the FLIGHT 50 Ventilator into an AC power
supply source when not in use. This will ensure the best
battery performance.
The flow resistance of the air inlet filter, located on the
right side of the ventilator, will likely increase with
repeated use. Ensure that the filter is changed regularly.
Only a FLIGHT MEDICAL approved patient circuit can be
used with the FLIGHT 50 Ventilator.

Safety Instructions
Cautions
Operator's Manual | 1-3
Only a FLIGHT MEDICAL approved exhalation valve can be
used with the FLIGHT 50 Ventilator.
Perform an exhalation valve calibration each time a clean
circuit/exhalation valve is installed.
The FLIGHT 50 Ventilator has been tested and found to comply with the
EMC limits according to the EN60601-1-1-2 standard class B. These limits
are designed to provide reasonable protection against harmful interference
in a typical medical installation. The equipment generates uses and can
radiate radio frequency energy and, if not installed and used in accordance
with these instructions, may cause harmful interference to other devices in
the vicinity. However, there is no guarantee that interference will not occur
in a particular installation. If it is found that this equipment causes harmful
interference with other devices, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving device.
Increase the distance between the equipment.
Connect the equipment into an outlet on a circuit different from
that to which the device (s) is connected.
Consult the manufacturer for help.
1.2 Cautions
Only use medical grade oxygen with the Air/Oxygen
Entrainment Mixer or Oxygen Blending Bag Kit.
Do not place liquid containers in the immediate vicinity or
on top of the FLIGHT 50 Ventilator. Liquids that get into
the ventilator can cause equipment malfunction and
damage.
After the FLIGHT 5050 Ventilator is serviced, it must
completely pass an Operational Verification Procedure
(OVP) before being returned to patient use.
An authorized FLIGHT MEDICAL factory-trained technician
must do all service or repairs performed on the FLIGHT
5050 Ventilator.

Safety Instructions
Contact Information
Operator's Manual | 1-4
Do not open the ventilator or perform service on an open
unit while connected to external power.
Use standard antistatic techniques while working inside
the ventilator or handling any electronic parts.
Clean all external accessories of the ventilator prior to
servicing.
Water in the oxygen supply can cause equipment
malfunction and damage.
Batteries contain Li-Ion. Do not discard them in an
incinerator or force them open. Batteries should not be
disposed of with normal waste.
Use the tools and equipment specified in this manual to
perform specific procedures.
