Chapter 11 - Cleaning and Maintenance Cleaning and Disinfection Guidelines
176 Apollo Operator’s Manual
Part Number: 90 38 237, 6th edition
Breathing system, absorber, and scavenger
• All parts of the breathing system, including
ventilator diaphragm, Y-piece, breathing
hoses, breathing bag (but not including the
Spirolog flow sensors)
• parts of the absorber
• parts of the AGS scavenging system
These parts can be thermally disinfected in an
automatic cleaning and disinfecting machine at 93 °C
(199 °F) for 10 minutes. Only neutral cleaning agents
and fully demineralized water may be used.
Chemical disinfectants need not be added for
thermal disinfection; they may cause corrosion.
Spirolog flow sensors
• Disinfect approx. 1 hour in 70% ethanol or
isopropanol solution. Leave the sensor to dry
in air for at least 30 minutes, otherwise the
sensor may be damaged by remaining alcohol
when calibrated.
• The flow sensor can be reused as long as it
can be calibrated successfully.
• Do not clean the Spirolog flow sensor in a
cleaning and disinfection machine or with
compressed air, water jets, brushes, etc.
These methods would damage the thin sensor
wires inside.
SpiroLife flow sensors
• Disinfect approx. 1 hour in 70% ethanol or
isopropanol solution. Leave the sensor to dry
in air for at least 30 minutes, otherwise the
sensor may be damaged by remaining alcohol
when calibrated.
• The SpiroLife flow sensor may be sterilized at
134
o
C (273
o
F) in hot steam.
CAUTION !
The breathing system valve plate must be sterilized
after washing in order to dry it. Correct operation of
the machine may be impaired and lead to failure if
the control areas in the valve plate are not dried
completely.
CAUTION !
The Spirolog flow sensor cannot be sterilized.
