8.3.2 Exhalation valve, proximal flow sensor and silicone line
After cleaning, the items should be disinfected with alcohol 70º. The external part should be
disinfected using a clean cloth moistened with alcohol 70 º and internal part by immersion.
After disinfection, the external parts should be dried with a clean, soft and dry cloth and the
internal parts should be dried so that the solution drains by gravity.
8.3.3 Distal flow sensor (Envitec SpiroQuant A+)
It is recommended to disinfect the flow sensor before use. For disinfection:
1.
Disconnect the distal sensor from the exhalation valve and the connector cable and wait 30
minutes.
2.
Immerse the sensor in 70% ethanol solution for 1 hour
3.
Allow to dry naturally for 30 minutes in the environment before reassembly.
•
The distal flow sensor must not be sterilized by steam.
•
For the internal disinfection of DISTAL flow sensor, do not use tools that may generate
mechanical forces, such as air or water jet, at the risk of damaging the filament.
•
Drying of DISTAL flow sensor should occur naturally in ambient air, so avoid the use of
compressed air or dryer.
•
If there is a possibility of the sensor remain infected, replace it promptly.
8.3.4 IRMA CO
2
sensor
The IRMA CO
2
sensor may be disinfected with a cloth moistened with 70% ethanol.
•
The airways adapters IRMA CO
2
sensor are unsterile supplies, so the steam sterilization can
damage these accessories.
