medicament nebulisation
Use only medicament nebuliser 84 12 935
(white central section).
If other medicament nebulisers are used, con-
siderable deviations may occur in the tidal volume
and the inspiratory O concentration.

To minimise the deviation from the set O
Evita 4 uses a mixed gas to drive the medicament
nebuliser.
In adult ventilation, this mixed gas is generated by
switching over between compressed gases (medical air
and oxygen) in synchronisation with inspiration.
In paediatric ventilation, the nebuliser is operated
continuously, with medical air or oxygen in alternation.
The drive gas of the medicament nebuliser therefore
roughly corresponds to the set FiO
