Puritan Bennett 560 Ventilator User's Manual - Covidien

Installation and Assembly
The Puritan Bennett 560 Ventilator can be used with an optional oxygen analyser with
minimum and maximum concentration alarms. Always measure the delivered oxygen with a
calibrated oxygen analyser (FIO 2 kit) that features a minimum and maximum concentration
alarm in order to ensure that the prescribed oxygen concentration is delivered to the patient.
Oxygen administered to the patient is introduced from an external source into the machine through the oxygen
connector at the rear of the ventilator. It is then integrated into the total volume of delivered gas. Remove
the oxygen inlet connector from the back of the ventilator when external oxygen is not in use.
The specific oxygen flow to the patient depends on the physiological characteristics of the patient and the
ventilator settings.
The oxygen flow setting should be adjusted for each patient and established in relation to a calibrated oxygen
monitor measurement. Since the factors that affect administered oxygen flow may change over time, you
must ensure that these settings always correspond to the current oxygen therapy objectives specified by the
physician.
4.8.2 Connecting the Oxygen Supply
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.
A connector (Figure 4-15, 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).

Before connecting the oxygen supply, ensure that the stud on the oxygen connector
(Figure 4-15, item 3) is protruding outwards.
Inspect the oxygen coupler (Figure 4-16, 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.
