Airvo 2 is cleaned according to local guidelines and self-cleaning routine when stopping treatment, after 7 days or earlier if needed. If a need for cleaning arises during ongoing treatment, stop airflow, move the water chamber first, then disconnect the proximal end of the AirSpiral and move over to the new system. The rest of the connections are kept intact. Start treatment on the system with the same settings as the previous Airvo 2 system. After starting treatment again, the T-connector can be moved to the new pole stand.
