The AIRVO 2 must be cleaned and disinfected between patients. This should
take place as soon as possible after use. The re-processing steps can be found in
the disinfection manual or on the swing tag. These steps must be carried out
between patients: Cleaning, High-level Disinfection and storage. Cleaning is
particularly important, you need to remove debris so that disinfection works
effectively, its easiest if you leave the AIRVO 2 on the mobile pole stand. Switch
off the unit and unplug from the mains/utility power socket. Remove the
breathing tube, water chamber and water bag and safely dispose of them. For
cleaning you will need: A cleaning sponge stick, Approved cleaning wipes,
A clean, damp, lint-free cloth and an approved cleaning solution. Follow the
manufacturer's instructions when using any cleaning solution, diluting it if
necessary before use. Avoid toxic abrasive or corrosive cleaners that may
damage the AIRVO 2. The disinfection manual or your local Fisher & Paykel
office can provide advice on appropriate cleaning products. The most important
part to clean is the outlet elbow between the right chamber port and
breathing tube port. Do not clean the left-hand chamber port as this can
damage the non-return valve located at this port. First, dip the cleaning sponge-stick
in a solution of warm water and mild detergent. Thoroughly clean the
outlet elbow from both ends, as far as possible,
continuously rotating the sponge-stick.
Rinse the cleaning sponge-stick under running water and using the same
rotation action, remove any residue from the outlet elbow. Discard the cleaning
sponge-stick. If using a disposable cloth, thoroughly clean the outlet elbow from
both ends, as far as possible continuously rotating the cloth with
your finger. Use an alcohol wipe, or apply an alcohol solution to a clean, damp,
disposable lint-free cloth, to wipe the outside surfaces of the unit.
The next step is high-level disinfection using the red disinfection tube. This
process heats the outlet elbow to at least 87 degrees Celsius for more than
30 minutes. Minimize the risk of cross-contamination by starting the
disinfection cycle immediately after cleaning. First, connect the red
disinfection tube to the AIRVO 2. One end of the disinfection tube has a blue
plastic connector. Lift the sleeve and slide the connector onto the unit. Push
the sleeve down to lock. Connect the red end of the disinfection tube to the
left-hand chamber port and push fully into position then fix the blue filter
cap securely onto the right chamber port. The AIRVO 2 is ready for disinfection.
Connect the power cable to the mains/utility power socket and start the
disinfection cycle by holding the on/off button for 3 seconds until the unit
beeps. The AIRVO 2 will turn on and run a series of calibration chicks raising an
alarm if any problems are detected. For example, you may be prompted to change
the air filter. If so remove the filter cover from the back of the AIRVO 2,
discard the old filter and insert a new one. Make sure the filter cover is
properly attached.
Once everything checks out, the disinfection cycle will begin, it will
take 55 minutes to complete and the display will count down the time
remaining. If any problems arise during disinfection, start the cycle again. If
the problem persists, refer to the disinfection manual for more information.
Once the countdown reaches zero, the disinfection cycle has completed
successfully in the disinfection numbers displayed. Finally turn the AIRVO 2 off by
holding down the power button, disinfection is complete. You can remove
the disinfection tube at this stage and seal the AIRVO 2 with a clean storage
cover. If you are not using the clean storage cover you may prefer to leave
the disinfection tube in place for storage. In either case it is best to
leave the AIRVO 2 on the stand, to protect it from bumps and knocks. Write
your name, the disinfection date and the disinfection number on the space
provided on the clean storage cover. Store the unit and disinfection kit in
an area suitable for medical devices, which is clean, dry and dust-free. Never
store the unit until it has been cleaned and disinfected. The AIRVO 2 is now ready
for the next patient.
