29.4 Cleaning Method
29.4.1 Ventilator
For cleaning use three clean, disposable,
absorbent, non-shedding cloths. Wipe clean with
the first cloth using a hand hot water/mild general
purpose detergent solution (as prescribed by the
appropriate hospital authority). Do not overload the
cloth with liquid. Remove the water/mild general
purpose detergent solution with the second cloth
using water only. Do not overload the cloth with
water. Wipe dry with the remaining cloth. Care
should be taken to ensure that the ventilator gas jets
in the ports are not blocked by any debris.
29.4.2 Flow Sensor
Wash in hand hot water/mild general purpose
detergent solution (as prescribed by the appropriate
hospital authority). Rinse with sterile water.
29.4.3 Exhalation block
The exhalation block can be immersed and agitated
in the detergent solution. Do not insert any objects
into the exhalation block. Rinse the exhalation block
in clean water, it must be allowed to dry thoroughly
before sterilization.
29.5 Disinfection Method
29.5.1 Ventilator.
For disinfection use two clean, disposable,
absorbent, non-shedding cloths. Wipe clean with
the first cloth using Alcohol (70% isopropanol). Wipe
dry with the remaining cloth.
29.5.2 Flow Sensor
Immersion in disinfectant recommended for use with
plastic materials. Immersion times and
concentrations must be in accordance with
manufacturer’s instructions. Rinse with sterile water.
29.5.3 Exhalation block
The exhalation block can be immersed in Alcohol
(70% isopropanol). The exhalation block must be
allowed to dry thoroughly before sterilization.
29.6 Sterilization Method
The silencer (N2186/01), flow sensor (N5402) and
exhalation block (N6622) must be sterilized
between use on patients. The ventilator cannot be
sterilized.
The exhalation block must be cleaned as an
essential prerequisite to sterilization.
For the silencer, flow sensor and exhalation block.
Autoclave with pure dry saturated steam at:
134ºC (277ºF) (Allowable variation of temperature
of +3ºC) at 220kPa (32psi) with a minimum holding
time of 3 minutes
or
121ºC (248ºF) (Allowable variation of temperature
of +3ºC) at 96kPa (14.1psi) with a minimum holding
time of 15 minutes.
The silencer can be autoclaved up to 25 times. The
body of the silencer should be marked after each
autoclave cycle with a high temperature, water
proof, permanent maker to indicate number of
sterilization cycles completed.
Note: Cleaning is an essential prerequisite to
disinfection and sterilization.
Warning: Ensure that the detergent solution
does not enter the unit or the exhalation block
gas ports on the side of the machine.
(Touchscreen) Do not use any abrasive
cleaners on the touchscreen surface.
Warning: Do not clean the flow sensor with
compressed air or water jet. As this will
destroy the sensor wires
Note: Alcohols such as 70% isopropanol have
a good activity against bacteria and viruses.
They should only be used after all visible
surface dirt has been removed from the area
to be disinfected.
Warning: Disinfectants containing
compounds similar to PHENOL or
ALKYLAMINES (Glucorrotamine) are
unsuitable.
