Aerosol data according to ISO 27427
The aerosol characteristics presented in these instructions for
use were determined in accordance with ISO 27427 using Sal-
butamol. If other solutions or suspensions are used for
nebulisation, the aerosol characteristics may differ from the val-
ues shown (particularly if they have greater viscosity).
The following data is based on tests according to a standard
which takes adult breathing patterns as a basis. Therefore,
these figures will probably differ from corresponding figures
that were calculated for populations of children and infants.
