1. Description
1.1 Purpose
SOMNOsmart 2 is a smartPAP appliance for treating
sleep-related respiratory disorders.
• SOMNOsmart 2 creates a “Positive Airway
Pressure” (PAP).
• SOMNOsmart 2 is a self-regulating appliance.
SOMNOsmart 2 identifies respiratory events and
varies the respiratory pressure accordingly.
• The air pressure generated supports the patient’s
air passages during sleep.
• The air pressure is administered through a mask.
• SOMNOsmart 2 can be used for persons aged
12 and over.
•SOMNOsmart 2 from software version 6.0;
generally from device no. 10,000:
The softPAP mode increases patient comfort by
means of a brief pressure reduction during the tran-
sition from inhalation to exhalation.
Important! SOMNOsmart 2 can prevent blockage of the air pas-
sages reliably only if the upper and lower pressure lim-
its prescribed for the individual patient by a doctor
have been determined in, for example, a sleep
laboratory.
SOMNOsmart 2 is not suitable for life-support use.

1.2 Function
SOMNOsmart 2 works on the principle of an
electrically powered flow generator, and delivers an
electronically controlled constant pressure level.
• A radial fan draws in ambient air through a filter
and delivers it to the outlet port. From here the air
flows through the hose system and the mask to the
patient.
•An oscillation generator creates a slight pneumatic
sinusoidal 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 com-
pared 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 in-
crease 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 WEINMANNsupport. This makes it
possible to identify apnoea, hypopnoea and
respiratory flow limitations.
•The expiration system before the mask prevents ac-
cumulation of CO2-enriched expired air in the tube
system.

6Description
EN
•An automatic ON/OFF switching system can be
activated in the SOMNOsmart 2. This allows the
appliance to be switched on by breathing out into
the mask. If there is no pressure for about 5 sec-
onds (e.g. because the mask has slipped off dur-
ing the night), the SOMNOsmart 2 switches itself
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 to facilitate falling asleep:
(Soft)start or start pressure function.
•(Soft)start function: when the device is switched on,
pressure is set to the (Soft)start pressure specified by
the doctor. The pressure limits then slowly rise to
specified values. The duration of the rise is adjust-
able. This function is suitable for patients who find
high pressure unpleasant when they are awake.
From software version 6.0,
the following option is also
available:
•Start pressure function: pressure remains at the set
value during the start time. After the start time has
expired, pressure is reduced to the lower pressure
limit. This function is suitable for patients who find
low pressure unpleasant when they are awake or
who require a high pressure rapidly after they fall
asleep.
• In softPAP mode, the respiratory flow curve is sub-
jected to continuous evaluation so that transitions
between inspiration and exhalation can be detect-
ed early. Therapy pressure is reduced before the
transition to exhalation to relieve exhalation. The
extent of the drop can be set to two levels: "slight”
(Level 1) and "normal” (Level 2). This increases pa-
tient comfort. Before the next inspiration starts,
pressure is raised to the therapy value again.

Description 7
EN
• If apnoeas or valid flow limitations occur during
sleep, softPAP mode is automatically deactivated
for the relevant period. If respiratory rate is too
high, softPAP mode is likewise deactivated tempo-
rarily. However, therapy pressure remains re-
duced during this period.
• In full-face mode, therapy is supported by a full-
face mask. Adaptation of pressure in response to
respiratory events is modified during this process.

8Safety Instructions

2. Safety Instructions
2.1 Safety regulations
Read these operating instructions carefully. They are
part of the appliance and must be kept available at all
times. Use SOMNOsmart 2 for the designated pur-
pose only (see “1.1 Purpose” on page 4).
For your own safety and that of your patients, and in
accordance with the requirements of Directive
93/42/EEC, please observe the following points:
Operating the appliance
Caution!
•Check that the supply voltage of the unit complies
with your supply voltage. The unit is designed for
voltages of 115 V and 230 V. One of these
voltages is detected automatically. With 12 V DC
or 24 V DC use an inverter available as an
accessory.
•Caution with oxygen: When using oxygen during
night-time therapy smoking and open fire are not
permitted. There is the risk of fire. The oxygen may
be deposited in the clothing, bed linen or the hair.
It is only removed when the room is ventilated
thoroughly.
•The supply of oxygen is only permitted with the use
of the O2connection valve WM 24042.
•As regards oxygen please make sure you observe
the safety information included in the instructions
for your oxygen system.
