2. Description
Note:
SOMNOsmart 2, SOMNOset and SOMNOsoft + are of largely identical basic design. They differ only in
the software, display and fascia film. SOMNOsoft + has no oscillation generator and no microphone.
2.1 Purpose of SOMNOsmart 2
SOMNOsmart 2 is a smartPAP device for treating
sleep-related respiratory disorders.
SOMNOsmart 2 generates positive airway
pressure (PAP).
SOMNOsmart 2 is a self-regulating device. It
recognizes respiratory events and varies the
airway pressure accordingly.
While the patient is asleep, the airways are
braced by the air pressure generated.
Airway pressure is administered by means of a
mask.
SOMNOsmart 2 can be used for people aged
12 years or more.
2.2 Purpose of SOMNOset
SOMNOset is a device for efficient adjustment to
CPAP patients. The device can work on a standalone basis or in conjunction with the remote
control SOMNOadjust or an extended user
interface of the SOMNOsupport software. The
recorded data can also be visualized and
evaluated with the aid of SOMNOsupport.
SOMNOset permits titration without the patient
coming to a sleep laboratory. Titration can be
carried out in the patient's familiar surroundings.
SOMNOset generates positive airway pressure
(PAP).
SOMNOset may be operated as a self-regulating
device. In that case SOMNOset recognizes
respiratory events and varies the airway pressure
accordingly.
While the patient is asleep, the airways are
braced by the air pressure generated.
SOMNOsmart 2 from software version 6.0; in general from device no. 10,000: The softPAP mode in-
creases patient comfort by means of a brief
pressure reduction during the transition from inhalation to exhalation.
Important!
SOMNOsmart 2 can reliably prevent closure of
the airways only if the upper and lower pressure
limits specific to the patient and prescribed by a
doctor have been determined, e.g. in a sleep
laboratory, and set accordingly.
SOMNOsmart 2 is not suitable for use as a life-
support system.
Airway pressure is administered by means of a
mask.
In the Autotitration mode the device determines,
during the titration night, a therapy pressure
(recommended titration pressure) that largely
prevents closure of the upper airways.
From the data recorded, the physician can
determine the required therapy pressure. This
pressure is set on the therapy device which is given
to the patient for long-term therapy following
titration.
SOMNOset can be used for people aged 12
years or more.
Important!
SOMNOset is not suitable for use as a life-support
system.

2.3 Uses SOMNOsoft +
SOMNOsoft + is a CPAP device for treating sleep-
related respiratory disorders.
SOMNOsoft + generates positive airway pressure
(PAP).
The softPAP mode increases patient comfort by
means of a brief pressure reduction during the transition from inhalation to exhalation.
SOMNOsoft + recognises respiratory events. This
permits efficient therapy control.
During sleeping, the patient’s airways are braced
by the air pressure generated.
2.4 Function of SOMNOsmart 2
SOMNOsmart 2 works on the principle of an
electrically powered flow generator delivering an
electronically controlled constant pressure level.
A radial fan draws in ambient air through a filter
and conveys it to the device outlet port. From here
the air flows through the hose system and the mask
to the patient.
An oscillation generator creates a slight sinusoidal
pneumatic oscillation in the air flow produced by
the device.
The airway and oscillation pressure is registered
via the pressure measurement tube in the mask.
The current oscillation pressure reading is
compared with an average value and the
preceding values. This evaluation of the oscillation
pressure makes it possible to identify any
significant change in airway resistance and hence
to increase or reduce the therapy pressure via the
flow generator.
The pressure present in the mask is shown in the LC
display. The microprocessor-controlled flow
generator regulates the pressure at the value
determined.
The device also records a respiratory flow signal
that can be output to a PSG system or read off with
the aid of SOMNOsupport. This makes it possible
to identify apnoea, hypopnoea and respiratory
flow limitations.
Airway pressure is administered by means of a
mask.
SOMNOsoft + can be used both in CPAP mode
and in softPAP mode for individuals aged 12 years
or more.
Important!
SOMNOsoft + can reliably prevent closure of the
airways only if the therapy pressure specific to the
patient and prescribed by a physician has been
determined, e.g. in a sleep laboratory.
SOMNOsoft + is not suitable for use as a life-sup-
port system.
The exhalation system before the mask prevents
accumulation of CO2-enriched expired air in the
hose system.
Auto switch-on can be activated on the
SOMNOsmart 2. The device can then be
switched on by breathing into the mask. If there is
no pressure for about 5 seconds (e.g. because the
mask is taken off), the SOMNOsmart 2 switches
off automatically.
Following a power failure and resumption of the
power supply, the status of SOMNOsmart 2 is the
same as it was before the power failure. The
stored data remain preserved.
There are two functions designed to make it easier
to go to sleep: (soft-)start or start pressure function.
(Soft-)start function: When this is switched on, the
pressure is adjusted to the (soft-)start pressure set by
the physician. The pressure limits then gradually increase to the set values. The time taken for this increase is adjustable. This function is suitable for
patients who find the high pressure unpleasant
while they are awake.
Additional function from software version 6.0:
Start pressure function: The pressure remains at the
set value throughout the start period. At the end of
the start period, the pressure is reduced to the lower pressure limit. This function is suitable for
patients who find low pressure unpleasant while
they are awake, or who need high pressure quickly after they have gone to sleep.
Description 7
Page 8
In softPAP mode the respiratory flow curve is analysed continuously to ensure timely recognition of
the transition between inhalation and exhalation.
Before the transition to exhalation the therapy pressure is reduced to make it easier to breathe out.
The size of this pressure reduction can be set in two
stages: “slight” (stage 1) and “normal” (stage 2).
This increases patient comfort. Before the next inhalation phase, the pressure is raised to the therapy figure once again.
2.5 Function of SOMNOset
If apnoea or valid flow limitations occur while the
patient is sleeping, the softPAP mode is automatically deactivated for the relevant period. If the respiratory frequency is too high, the softPAP mode is
also temporarily deactivated. However, the therapy pressure remains reduced during this period.
In full face mode the device supports therapy with
a full face mask. The event-related pressure adjustment is modified accordingly.
SOMNOset works on the principle of an
electrically powered flow generator delivering an
electronically controlled constant pressure level.
A radial fan draws in ambient air through a filter
and conveys it to the device outlet port. From here
the air flows through the hose system and the mask
to the patient.
An oscillation generator creates a slight sinusoidal
pneumatic oscillation in the air flow produced by
the device.
The airway and oscillation pressure is registered
via the pressure measurement tube in the hose
system.
The current oscillation pressure reading is
compared with an average value and the
preceding values. This evaluation of the oscillation
pressure makes it possible to identify any
significant change in airway resistance and hence
to increase or reduce the therapy pressure via the
flow generator.
The pressure present in the mask is shown in the LC
display. The microprocessor-controlled flow
generator regulates the pressure at the value
determined.
The values determined are recorded. In
Autotitration mode, the recommended therapy
pressure is calculated at the end of the titration
night.
The device also records a respiratory flow signal
that can be output to a PSG system or read off with
the aid of SOMNOsupport. This makes it possible
to identify apnoea, hypopnoea and respiratory
flow limitations.
The exhalation system before the mask prevents
accumulation of CO2-enriched expired air in the
hose system.
To make it easier for the patient to go to sleep, an
automatic Softstart system is incorporated for the
APAP and CPAP modes. When this is switched on,
the pressure is reduced to the Softstart pressure set
by the physician. The therapy pressure then
gradually increases to the set value. The period for
the pressure rise can be set in 5-minute steps
between 0 and 30 minutes. The automatic
Softstart system can be locked out by the
physician.
Auto switch-on can be activated in APAP and
CPAP modes. The device can then be switched on
by breathing into the mask. If there is no pressure
for about 5 seconds (e.g. because the mask is
taken off), the SOMNOset switches off
automatically.
If the power supply is interrupted and then
restored, data recording starts afresh in all modes.
In that case, pressure adjustment and event
evaluation restart in the Autotitration and APAP
modes. In the Pressure Profile and CPAP modes,
titration or therapy are continued in the status that
was active before the interruption. The stored data
remain recorded despite the interruption.

2.6 Functional description of SOMNOsoft +
SOMNOsoft + works on the principle of an elec-
trically powered flow generator delivering an electronically controlled constant pressure level.
A radial fan draws in ambient air through a filter
and conveys it to the device outlet port. From here
the air flows through the hose system and mask to
the patient.
The airway pressure is registered via the pressure
measurement tube in the mask.

In softPAP mode the respiratory flow curve is analysed continuously to ensure timely recognition of
the transition between inhalation and exhalation.
Before the transition to exhalation the therapy pres
sure is reduced to make it easier to breathe out.

The device also records a respiratory flow signal
that can be output to a PSG system or read off with
the aid of SOMNOsupport. SOMNOsoft + recog-
nises apnoea, hypopnoea and respiratory flow
limitations. This permits efficient therapy control.
The exhalation system in front of the mask prevents
accumulation of CO2-enriched expired air in the
tube system.
An automatic Softstart system is provided to enable
the patient to go to sleep more easily. When this
is switched on, the pressure is reduced to the Softstart pressure set by the physician. The therapy
pressure then gradually increases to the set value.
The period for the pressure rise can be set in 5minute steps between 0 and 30 minutes. The automatic Softstart system can be locked out by the
-
physician.

is taken off), SOMNOsoft + switches off automatically.
Following a power failure and resumption of the
power supply, the status of SOMNOsoft + is the
same as it was before the power failure. The
stored data remain preserved.

3. Servicing
3.1 Intervals
The two filters 45 and 46 need to be checked regularly for soiling.
• Coarse dust filter 45 must be changed every 6
months.
• Fine filter 46 must be changed at least every
250 operating hours.
• The pressure measurement tube 11 must be
changed at least every 6 months – and more
frequently if soiling is heavy.
The following preventive maintenance measures must also be carried out:
1. Service after every 5000 operating hours
(service symbol 23 appears in display and
must be reset after every service).
2. Service after a maximum of 2 years (see
service label on back of device).
3. The parts exposed to the air flow must be
cleaned every 10,000 hours or 4 years.
4. Every 2 years the battery on the Smartboard or
Softboard must be replaced.
After every service, replace the service label 87
with one bearing the new data (see “9. Spare
parts” on page 46). Use a hole punch or nail
scissors (V-shaped notch) to mark the month. Affix
the new service label to the left of the filter cover.
For hygiene reasons we recommend:
• replacing the complete mask system every 6 to
12 months depending on soiling, and
• replacing the expiration system in accordance
with the relevant operating instructions.
