Precautions Regarding Oxygen
WARNING
Maintenance Precautions (Cont’d):
•
For environmental protection, the ventilator and its components, whatever their respective conditions
of operation, cannot be disposed of with household waste and must be submitted for suitable selective
collection and possible recycling. Observe all applicable regulations when disposing of the ventilator
and any of its components.
•
If the device is damaged, its external housing is not correctly closed, or it behaves in a way that is not
described in this manual (excessive noise, heat emission, unusual odor, alarms not triggered during the
start-up procedure), the oxygen and power supplies should be disconnected and use of the device
stopped immediately.
•
After replacing the ventilator’s internal battery, push on the battery’s cover from the rear towards the
front to take pressure off the cover mounting brackets, thereby avoiding breakage when the screws are
tightened.
WARNING
•
The ventilator must not be used with flammable anesthetic substances.
•
Oxygen therapy for patients with respiratory failure is a common and effective medical prescription.
However, be aware that excessive oxygen use is likely to lead to serious complications—including, but
not limited to, patient injury.
•
Strictly follow the instructions provided in section 4.8.2, “Connecting the Oxygen Supply” , which
include the use of a flow regulator and special coupler.
•
To avoid injury to the patient and/or possible damage to the ventilator: before using the ventilator, use
a flow meter (flow regulator) to regulate the oxygen supply to specifications before connecting the
ventilator to the oxygen supply.
•
The Puritan Bennett 540™ Ventilator does not include an oxygen analyzer. Always measure the
delivered oxygen with a calibrated oxygen analyzer that features a high and low concentration alarm in
order to ensure that the prescribed oxygen concentration is delivered to the patient.
•
Ensure that the oxygen supply pressure to the machine never exceeds 7.25 psi (49.99 kPa) or a flow of
15 lpm. Refer to
Table A-8 on page A-3 for volume and sensitivity tolerances.
•
In the event of an oxygen leak, shut down the supply of oxygen at its source. In addition, remove and/or
keep any incandescent source away from the device, which may be enriched with oxygen. Air the
affected room to bring the oxygen level down to normal.
•
The hose connecting the ventilator to the oxygen source must be designed exclusively for use with
medical-grade oxygen. Under no circumstances should the oxygen hose be modified by the user. In
addition, the hose must be installed without the use of lubricants.
•
Ensure that the only gas supplied to the ventilator through the dedicated oxygen supply connector is
medical-grade oxygen.
•
The coupler must not remain connected to the oxygen connector unless it also connected to a leak-
proof, external oxygen gas source. When an oxygen supply is not being used with the ventilator,
disconnect the oxygen source completely from the ventilator.
•
To prevent any interference with the internal sensors of the ventilator, do not install a ventilator
humidifier upstream of the ventilator.
