subjects to allow settling of previously aerosolized particles in the
measuring device.
It is recommended that the flowhead be regularly cleaned according to
the guidelines of the user’s facility.
In the event of visible contamination of the flowhead cones or flowhead
element, they should be cleaned or disinfected as described in the
accompanying table. The flowhead conditioning meshes should also
be replaced in the event of damage, or if visibly contaminated.
The frequency of cleaning and disinfecting is dependent on the
Facility’s Risk Assessment, usage, and test environment, but it should
be at least monthly or every 100 subjects (500 blows).
It is recommended that the flowhead—flowhead complete and
flowhead connection tube—be replaced annually.
