The unique gas mixing system allows a precise oxygen concentration to be selected which will be
delivered irrespective of the inspiratory pressure or tidal volume. If only oxygen is supplied, the
concentration can be set between 45 (approx.) and 100% oxygen but if both oxygen and compressed
air are available then 21% to 70% oxygen can be selected. With 45% (approx.)/21% oxygen
selected 2/3 of the gas supplied to the patient circuit is entrained from the atmosphere, thereby
reducing consumption of cylindered gas by the same proportion.

Selection of the IMV function increases the set expiratory time by a factor of 10 so that this can be
extended up to 40 seconds – allowing time for spontaneous breathing between the mandatory
ventilations.

PEEP can be set using a control on the ventilator. This has an uncalibrated scale but can be finely
adjusted by reference to the actual value as indicated by the patient pressure manometer during
ventilation.

For the spontaneously breathing patient, airway pressure and oxygen concentration can be
controlled using the CPAP function. This function is also automatically introduced during the
expiratory phase whenever IMV is selected.

The exhalation valve is mounted on the ventilator output manifold and consists of a twist-to-remove
housing and a silicone rubber valve element. Both items can be autoclaved for sterilisation (see
section 5(d)).

babyPAC ventilators have been supplied which are suitable for ventilating patients whilst being
subjected to MRI procedures. See Sections 4(f) & 8(g) for further details concerning MR
Compatibility.

All parts which contain metals and which are MRI compatible are marked “/MRI” and where this
feature is required for additional parts and accessories /MRI should be added as a suffix to the order
code of each part ordered (See Section 7).

The control module is designed to be mounted in a variety of ways as described under Section 2 (d)
‘Mounting Options’. A sling is available to enable the unit to be carried from the user’s shoulder.
It may also be carried, together with a compressed gas cylinder, within a Pneupac

®

‘Instant

Action’ carrying case. A wide range of attachments and brackets are also available. The babyPAC
ventilator may be driven by oxygen and/or air from a compressed gas cylinder, pipeline system or
one of the airPAC portable compressors.
