Insp. O2 concentration during medicament nebulisation
Insp. O2 concentration during medicament
nebulisation
Use only medicament nebuliser 84 12 935 (white central
section).
If other medicament nebulisers are used, considerable
deviations may occur in the tidal volume and the inspiratory
O2 concentration!
To minimise the deviation from the set O2 concentration,
EvitaXL 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 FiO2.
The graph shows the possible deviations of the applied O2
concentration as a function of the set FiO2 with a minimal
inspiratory flow (15 L/min) in adult ventilation or at ventilation
frequencies above 12 bpm in paediatric ventilation.
