Additional functions
Medicament nebulisation
Inflammable agents must not be nebulised!
They may be ignited by the glowing flow sensor.
During adult ventilation
Applicable in every ventilation mode. EvitaXL applies the medicament
aerosol in synchronisation with the inspiratory flow
phase and maintains the minute volume constant.
The medicament nebuliser is supplied by the ventilator with
medical air, O2 or a mixture of medical air and O2 according to
the set O2 concentration. Deviations in the O2 concentration
are thus kept to a minimum.
In extreme cases (with a minimum inspiration flow of
15 L/min), the deviations can be up to ±4 % by volume*.
To avoid greater deviations, medicament nebulisation is automatically
switched off at inspiratory flows below 15 L/min.
During paediatric ventilation
Medicament nebulisation is possible in the pressure-controlled
paediatric ventilation modes.
In volume-controlled ventilation modes, medicament nebulisation
is only possible with the supplementary AutoFlow ®
function.
Unlike in adult ventilation, the medicament nebuliser nebulises
continuously in paediatric ventilation, but the aerosol generated
during expiration does not reach the lungs.
Depending on the set O2 concentration, the medicament nebuliser
is supplied with medical air or O2 or a mixture of medical
air and O2 by the ventilator. Deviations in the O2 concentration
are thus minimised.
For breathing rates above 12 bpm, please refer to the graph
on page 228.
The maximum possible deviations in the O2 concentration are
±4 % by volume.
* For a detailed description of the insp. O2 concentration during
medicament nebulisation, refer to page 228.
Additional functions
Medicament nebulisation
We recommend that you do not use the medicament nebuliser
at breathing rates of less than 12 bpm.
For breathing rates of less than 12 bpm, the deviations in
the O2 concentration may be much greater in extreme
cases.
These deviations cannot be detected by the device's internal
O2- concentration monitor.
The minute and tidal volumes displayed may be considerably
higher or lower than those actually applied to the patient on
account of tolerances in the nebuliser flow. Pressure-controlled
ventilation is therefore recommended during nebulisation.
The measured values prevailing before nebulisation
must be taken into account if necessary.
If the VT and MV values diverge strongly, the ventilation pressure
can be used for assessment of the ventilation. VT and MV
values can be compared by comparing the difference between
PEEP and plateau pressure before and during nebulisation.
In order to avoid false alarms and ensure monitoring:
● Adjust both alarm limits for MV in line with the actual value.
● Use additional monitoring, e.g. SpO2, if necessary.
Only the medicament nebuliser 84 12 935 (with white
middle part) may be used.
If other pneumatic medicament nebulisers are used,
there may be major deviations in tidal volume and inspiratory
O2 concentration!
