2. Description of the equipment
2.1 Intended use SOMNOcomfort 2 and SOMNOcomfort 2e
SOMNOcomfort 2 and SOMNOcomfort 2e are CPAP-Therapy units for the treatment of sleep related
respiratory disorders.
• SOMNOcomfort 2/SOMNOcomfort 2e
creates continuous positive airway pressure
(CPAP).
• While sleeping, the patient’s airways are
stabilized by the applied pressure.
• Air pressure is administered by means of a
breathing mask.
• SOMNOcomfort 2/SOMNOcomfort 2e can
be used for patients age 12 and up.
Important!
SOMNOcomfort 2/SOMNOcomfort 2e can
only reliably prevent airway closure when the
CPAP pressure prescribed by a doctor for the
specific patient has been calculated, e.g. in a
sleep laboratory. Pressure is set by either using the
SOMNOadjust remote control or
SOMNOsupport at the units front control panel.
SOMNOcomfort 2 and SOMNOcomfort 2e are
not designed for life support.
2.2 Intended use SOMNObalance and SOMNObalance e
SOMNObalance and SOMNObalance e are autoCPAP devices for treating sleep-related respiratory
disorders.
• SOMNObalance/SOMNObalance e
creates positive airway pressure (PAP),
• While sleeping, the patient’s airways are
stabilized by the applied pressure.
• The pressure is administered by a nasal or fullface mask.
• SOMNObalance/SOMNObalance e can
be used for patients age 12 and up.
• SOMNObalance/SOMNObalance e
detects respiratory events and varies airway
pressure accordingly.
• SOMNObalance/SOMNObalance e can
be operated with or without the
SOMNOaqua respiratory air humidifier.
• SOMNObalance/SOMNObalance e
displays therapy data on the device.
Important!
SOMNObalance/SOMNObalance e can only
reliably prevent airway blockage if the upper and
lower pressure limit prescribed by the doctor on a
patient-specific basis has been determined and set
accordingly, for example in a sleep laboratory.
SOMNObalance and SOMNObalance e are
not designed for life support.
8 Description of the equipment
Page 9
2.3 Functional description SOMNOcomfort 2 and SOMNOcomfort 2e
SOMNOcomfort 2 and SOMNOcomfort 2e operate according to the principle of an electrically driven flow
generator, with the pressure level being controlled electronically.
• A fan draws in ambient air via a filter and
conveys it to the unit outlet. From here the air
flows through the breathing tube and the mask
to the patient.
• A pressure sensor measures the pressure at the
unit outlet and shows this in the display. The
microprocessor-controlled flow generator
controls the pressure to the set value and
reduces fluctuations in pressure caused by
breathing.
• A softstart automatic system is installed to help
the patient fall asleep more easily. When the
unit is switched on, the CPAP pressure starts at
the initial pressure selected by the doctor and
is then slowly increased to the setpoint
pressure selected. The time of the pressure
increase can be adjusted between 5 and
30 minutes in 5 minute increments.
• The therapy unit offers an automatic on/off
feature. The unit can then be switched on by
breathing into the mask. If there is no pressure
for approx. 15 seconds (e.g. because the
mask has been removed), it will switch off
automatically.
• The therapy parameters are set by trained
personnel using the remote control system
SOMNOadjust or the evaluation program
SOMNOsupport.
• The therapy unit will automatically save all
settings in the event of a power failure. This
means that the unit does not need to be reset
when power is restored.
2.4 Functional description SOMNObalance and SOMNObalance e
• A fan draws in ambient air via a filter and
conveys it to the unit outlet. From here the air
flows through the breathing tube and the mask
to the patient.
• The exhalation system upstream of the mask
prevents the accumulation of CO2-enriched
exhaled air in the tube system. During sleep,
the patient's airways are braced by the air
pressure generated.
• The pressure in the mask is shown in the
therapy device display. The device determines
a respiratory flow signal which can be output
to a PSG system or also read out using
SOMNOsupport.
• The device analyzes the pressure and
respiratory flow signals and detects respiratory
events (e.g. apneas, hypopneas, flow
limitations and snoring).
• In APAP mode, therapy pressure is
automatically increased in the event of
obstructive respiratory events, but no higher
than the upper pressure limit prescribed by the
doctor. Once the events are over, therapy
pressure is slowly reduced again.
• The device can be operated in APAP and
CPAP modes, in each case with softPAP
exhalation relief as an option.

the respective part of the housing (see also
Chapter 7.12, Page 31 and Chapter 7.13,
Page 31).
5.2.5 Checking the control panel and indicators
1. Make sure that front panel foil of the control
panel is attached flush and tight. If this is not
the case, replace the foil (see chapter “7.7”
on page 26).
2. You should now establish the power supply
by connecting the power supply 3 and the
power supply cable 2 to the unit and an
available power outlet.
3. Close the opening of the mask, e.g. using your
thumb or hand and hold it closed.
4. Push the on/off switch 19 to switch the device
on.
On the display, the total hours of operation
will be indicated for 3 seconds before the
current measured pressure will appear.
5. Press the Softstart button 20. The display will
change.
6. Switch the unit off using the 19 switch.
The display will show the date and the day’s
length of therapy for a short while.
Subsequently only “0” and “A” or “M” will be
shown.

5.2.6 Checking proper functionality of the therapy unit
1. Switch on the therapy unit.
2. Close the opening of the mask, e.g. using your
thumb or hand and hold it closed.
3. If the mask test is activated on
SOMNObalance/SOMNObalance e,
switch it off using button 20. If softstart is
switched on, then deactivate this as well,
likewise using button 20.
The radial fan will transport air to the mask
through the breathing tube, and the display
will show the current pressure in hPa.
4. Compare the pressure shown on the display
with the CPAP pressure prescribed. After
approx. 1 minute the maximum allowable
pressure deviation is ± 0.2 hPa.
5. Replace the masks with pressure measurement
adapter WM 23456 and connect it to an
exhalation system, e.g. WM 23685. Seal the
top opening with the red plug for drying
(WM 23639).
6. Connect the lateral connector to a pressure
measurement device.
7. Switch on the therapy device. If softstart is
active, switch it off using button 20.
8. Compare the value displayed by the pressure
measurement device with the value in the LC
display. After approx. 1 minute the maximum
allowable pressure deviation is ± 1 hPa.
9. Press the 20 button to activate softstart. The
softstart indicator 15 will appear and the
display will show the softstart time.
Concurrently, the CPAP pressure will be
reduced to the set softstart initial pressure.
The initial softstart pressure can be adjusted.
(see chapter “2.3” on page 9).
10. The pressure increases slowly and reaches the
CPAP pressure after the time selected. The
softstart indicator 15 will disappear.
With SOMNObalance/SOMNObalance e,
it is the set bottom pressure limit, not the
prescribed CPAP pressure, which is reached
in APAP mode.
11. Switch the therapy unit off.
12. Press and hold softstart button 20 until the
setting option for Automatic on/off
(SOMNOcomfort 2/SOMNOcomfort 2e) or
the SoftPAP stage (SOMNObalance/
SOMNObalance e) appears. On
SOMNObalance/SOMNObalance e, press
the humidifier button to reach the setting option
for Automatic on/off.

Final test 17
Page 18
13. In order to switch to the “A” setting, push the
on/off button 19.
– The therapy unit will now switch on
automatically when breathing into the mask
(pressure > 0,5 hPa),
– If the mask is removed, the unit should
switch off after approx. 15 seconds.
14. Switch the unit off using the button 19. The
display will show the date and the day’s
length of therapy for a short while.
Subsequently only “0” and “A” will be shown.
5.2.7 Checking proper function of the humidifier
1. Check the plastic housing visually:
if tears/damage or heavy soiling are found,
the plastic parts or gaskets must be replaced.
2. Fill the humidifier up to the mark with water.
3. Check whether the humidifier is leaking.
4. Empty the water.
5. Now pour in about 50 ml of water.
6. Attach the humidifier.
7. Attach the breathing tube to the unit.
8. Switch the therapy unit on.
9. Switch the humidifier on by pressing the
humidifier button on the therapy unit.
10. Set heater level 6 on the therapy unit.
11. Check whether the humidifier is getting
warmer.
12. Remove the breathing tube by pressing the
adapter’s locking button.
