regular therapy, with a greater quantity
of nebulised medicine and particles at
the ideal size for treatment of the entire
respiratory tract .
Sidestream uses the exclusive Diamond
Jet technology, guaranteeing a more uni-
form nebulisation: in fact, the medicine
crosses through 4 channels indepen-
dent of the air flow channel. This avoids
premature nebulisation within the tubes
(13).
The Sidestream nebulizer cup features
the unique Venturi Double Effect, whe-
re air enters the nebulizer cup from the
bottom (compressed air) - like conven-
tional nebulizer cups, as well as from the
top. The additional air flow from outside
the nebulizer cup combined with the air
flow from the compressor conveys even
more particles to the lungs (14).
At the nebulizer cup summit, the medici-
ne is nebulised by the air produced by the
compressor and air drawn from outside.
A central deflector creates two currents
of nebulised air, which hit the nebulizer
cup walls. This impact causes the largest
particles to drop to the nebulizer cup floor
and reinitiate the cycle, while those with
a suitable dimension leave the nebulizer
cup and are breathed in by the patient.
This particular technology significantly
increases particles flow and reduces
therapy time, which has a critical impact
on the treatment's efficiency and its ac-
ceptance, especially with children.
NEBULIZER CUP
EFFECTIVENESS
The special configuration of Sidestream
enables medicine to penetrate the respi-
ratory tracts more easily, thanks to the
optimal size of nebulised aerosol parti-
cles. With the Sidestream nebulizer cup,
80% of particles are smaller than 5 mi-
cron (from 1 to 5 micron) and can reach
and deposit in the lower airways, while
particle size in traditional nebulizer cups
varies, so only 50% of particles reaches
the lower airways.

NEBULISATION
RATE
The design of the Sidestream nebulizer
cup also reduces treatment length, with
medicine administered quickly and effec-
tively. As the table shows, Sidestream ne-
bulises the same amount of medicine as
a traditional chamber in half the time.

NEBULISATION
QUALITY
Sidestream produces same-size, optimal
particles to maximise breathable flow.
