Insp. O 2 Concentration During Medicament Nebulisation - Dräger Evita 2 dura Instructions For Use Manual

Insp. O concentration during medicament nebulisation
2
Use only medicament nebuliser 84 12 935 (white central
body).
If other medicament nebulisers are used, considerable
deviations may occur in the tidal volume and inspiratory
O concentration!

To minimise the deviation from the set O
Evita 2 dura generates a mixed gas to drive the medicament
nebuliser.
In adult ventilation, this mixed gas is generated by switching
over the 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
