Sophie The flexible neonatology ventilaton system
In intensive cooperation with renowned physicians, Fritz Stephan GmbH has succeeded in
developing SOPHIE as a neonatology ventilator system based on the proven cutting-edge
technology of STEPHANIE thus ensuring highest levels of efficiency, design and operability.
With its flexibility and performance, SOPHIE can be adapted easily and reliably to the individually required ventilation situation for premature and newborn infants.
In addition to conventional and high frequency ventilation strategies it also allows non-invasive
ventilation. This system sets new standards of non-invasive ventilation of premature and newborn
infants by combining the innovative patient interface „EasyFlow nCPAP“ with dead space free
ventilation control via external respiration sensor.
Ventilation modes
SOPHIE offers all established conventional pressure
controlled ventilation forms. Convenient undelayed
change between various ventilation modes are
possible by simple menu selection.
As a matter of course, our well proven volume
guarantee is included in the range of features.
It controls ventilation pressure of the subsequent
inspiration according to the previously measured
expiratory tidal volume.
High Frequency Ventilation HFOV
SOPHIE is a ventilator that combines highfrequency oscillation and conventional ventilation
strategies in one unit. The HFOV, which is
available by pressing a button, can be carried out
without any delay or need to change the patient tubes.
The integration of the heated humidifier avoids any
additional compressible volumes that would reduce
the HFOV performance.
Optimum respiratory gas conditioning
The integrated respiratory gas humidifier provides
the patient simply and safely with ideally heated and
humidified respiratory gas through molecular humidification. The intelligent control system prevents any
condensation in the heated, temperature-monitored
patient tubes. SOPHIE thus needs absolutely no
additional equipment to condition the respiratory gas.
Non-invasive Ventilation (NIV)
The benefits of a non-invasive ventilation therapy
for newborn or prematurely born babies have been
established by several scientific studies (e.g. COIN
study). The application of NIV permits lung-protective ventilation strategies thus helping reduce the
occurrence of air leak syndromes and BPD.
The use of NIPPV reduces the danger of ventilation
failure after extubation and therefore significantly
reduces the incidence of reintubation. A newly
developed system of Fritz Stephan GmbH detects
the abdominal movement of patients by means of
an external respiration sensor. This is then converted
into a stable, fast-reacting (<30ms) trigger signal, thus
allowing SNIPPV which can further improve the
efficiency of ventilation.
Although the BPD rate has the tendency to be
lowered by an early application of NIV, the risk of
pneumothorax may increase (especially in very
prematurely born babies) since exogenous surfactants
can only be safely applied to an intubated patient.
Due to its innovative control system, SOPHIE allows
swift changes between invasive and non-invasive
ventilation thus allowing the optimal support of the
so-called INSURE method
Innovative design
SOPHIE's innovative design combines top quality
aluminium and glass surfaces to produce an aesthetic
SOPHIE's compatibility with STEPHANIE is
another advantage: patient components, tubes and
sensors are identical thus allowing an easy exchange
between the two units.
Intuitive operation concept
All settings can be adjusted with just one single
knob. The user is guided systematically through the
ventilation menu, with the display only showing the
relevant parameters for the chosen ventilation form.
The parameters can be adapted easily to the patient's
needs even before starting ventilation. Efficient monitoring permits safe control at all times. Clearly allocated buttons make it much easier to separately adapt
the relevant parameters during ventilation.
