CAUTIONS
1. Do not sterilise the ventilator control unit.
The patient block assembly must be
removed from the control unit before
sterilisation ( see section 6.2.4).
All other internal components are not
compatible with sterilisation techniques
and damage may result.
2. For ventilator components which require
sterilisation, peak sterilisation
temperatures should not exceed 136oC
(275oF) to prevent possible damage.
(See section 6).
3. Those parts suitable for ethylene oxide
sterilisation should, following sterilisation,
be quarantined in a well ventilated area to
allow dissipation of residual gas absorbed
by the components.
Follow the steriliser manufacturer’s
recommendations for any special aeration
periods required.
4. The exhalation valve located in the
bellows base assembly and the paediatric
bellows adaptor must be cleaned and
sterilised separately. See section 6.
5. Care must be taken not to let any liquid
run into the control unit; serious damage
may result.
6. Always check for correct fitment, and carry
out a full function test before clinical use, if
the bellows has been removed and
refitted for any reason. See section 6.
7. Damage may occur to the battery if it is
allowed to remain in a discharged state.
Check the battery frequently if the
ventilator is in storage (see Appendix 1).
8. Fresh gas compensation is disabled if :
a) The spirometry system is turned OFF
through the menu system, or
b) The spirometry system is not functioning
correctly.
9. Fresh gas mixture compensation is disabled
if :
a) The spirometry system is turned OFF
through the menu system, or
b) The spirometry system is not functioning
correctly.
c) The O
2
monitor is switched OFF.
10. Circuit compliance is not activated until
Fresh Gas Compensation is switched
OFF.
NOTES
1. The term ‘cycle’ is used to designate the
transition to the exhalation phase.
2. The term ‘trigger’ is used to indicate the
transition to the inhalation phase.
