SECTION 6 MAINTENANCE
(a) General
Because of the high reliability and long life of the control elements used, the babyPAC ventilator
does not require any specific planned servicing. Service is only required if calibration needs to be
restored, if component failure occurs or if damage is incurred.
It is recommended that maintenance is carried out at two levels. At the first level, the procedure
specified in Section 3(b) should be followed at regular intervals, typically once a month,
irrespective of use, and a record kept by the use of the log sheet at the back of this manual. At the
second level, the performance of the ventilator should be checked as specified in Section 6(b).
(b) Performance Checking
Performance checking of the babyPAC ventilator must be carried out with equipment calibrated to
ensure accuracy under the flow patterns generated by the machine. It should be carried out by
suitably trained personnel. If suitable personnel or equipment are not available it should be
checked by the Pneupac
®
as part of a service contract or its authorised representative.
Recommended performance checking procedures and suitable equipment are detailed in the product
maintenance manual which is available to suitably trained personnel.
The frequency of performance checking should be determined by the user depending upon the
intensity of use. Normally, this would be not more often than once every 6 months but at least
once every 2 years.
(c) Changing of battery
The specified batteries will give several years of service under normal use conditions but to avoid
the need to locate a spare battery whilst the ventilator is in field service it is recommended that the
battery is replaced as a matter of routine at the same time as the performance checking as specified
in Section 6(b) above. (If the equipment is checked every 6 months and the date of the battery
changing is recorded, replacement is only necessary every second check, i.e. annually). The
procedure for changing the battery is as follows (see section2(c) 15 for precautions in MRI use): -
(i)
Ensure the function selector switch is set to ‘O’.
(ii) Remove the battery retaining cap, situated on the right hand side of the control module, by
twisting a quarter of a turn anti-clockwise using a coin in the slot provided.
(iii) The battery will be automatically pushed out of its holder.
(iv) Fit the replacement battery, base first, into the holder. (The positive cap must be showing
outwards).
(v) Replace the battery retaining cap by pushing it against the battery and twisting clockwise
until it stops after a ¼ turn. (The cap is reversible so ensure that the marking on the outside
of the cap corresponds to the battery being used. See section 2(c) 15).
(vi) Select 'CMV+PEEP’ on the main pneumatic switch and check that the alarm system runs
through the start-up self checking procedure (See section 3(b) 5).
