8 Maintenance
Certain maintenance operations are the responsibility of the user, when others must be performed by
a technician.
For any operation requiring the machine to be opened, call on a trained, qualified technician.
8.1 By the user
The user must:
•
If using a patient circuit with water trap, empty the patient circuit water traps as often as neces-
sary,
•
Clean and disinfect the reusable elements between each patient: the patient circuit, the expiratory
flow sensor, and the expiratory valve (see Expiratory assembly: Flow expiratory valve on
page 99).
•
Between patients, replace the non-reusable elements (circuit, filters, expiratory valve, expiratory
flow sensor, IRMA
™
CO2 measurement probe adapter),
•
Replace the bacteriological filter at the ventilator output according to manufacturer recommenda-
tions,
•
Replace the Monnal Clean’In HEPA air intake filter every six months,
•
Replace the O2 sensor (see O2 Cell on page 106) and expiratory flow sensor in the event of fail-
ure,
•
Check the remaining battery capacity approximately every six months (connect a test lung to the
ventilator, start ventilation, and check that battery capacity is adequate),
•
Replace the extractable battery after two years. The extractable battery's commissioning date is
shown on the label (see Extractable battery on page 24).
•
Go through a checklist before each use (see Checklist on page 139).
8.2 By the technician
The technician carries out maintenance once a year while also checking that the machine functions
and performs correctly. Access to maintenance is protected by a code. This code is provided to the
qualified technician via a call to the hotline, following technical training by
Air Liquide Medical Systems
or their authorized representative. The ventilator counts two operational parameters: number of hours
of ventilation, and number of hours that the machine is powered up.
These times can be viewed at any time in the start-up and stand-by screen:
