4.8.2 Connecting the Oxygen Supply
A connector ( Figure 4-14 , item 1) for an external low pressure oxygen source is available at the rear of
the ventilator. It is essential that you also use the special coupler (item 2) supplied with the ventilator
to attach the external low pressure oxygen source to the connector. The connector is also fitted with a
non-return airtight valve system. The non-return airtight valve system includes a stud (item 3) and a
locking tab (item 4).

WARNING
•
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.
•
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-17 on page A-12.
•
ThePuritan Bennett 540™ 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.
WARNING
•
Ensure that the only gas supplied to the ventilator through the dedicated oxygen supply connector is
medical-grade oxygen.
•
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.
Caution
•
Before connecting the oxygen supply, ensure that the stud on the oxygen connector ( Figure 4-14 , item 3) is
protruding outwards.
•
Inspect the oxygen coupler ( Figure 4-15 , item 2) before use to ensure it has its black O-ring attached and in
good condition. Do not use an oxygen coupler with a missing, damaged, or worn O-ring.
