2. Description of device
2.1 Intended use
SOMNOvent CR is an automatically-regulating CS therapy device with autoTriLevel
principle suitable for treating patients from the age of 12
•with periodic respiration or Cheyne-Stokes breathing (e.g. in
cardiac insufficiency)
•as well as central, mixed and complex sleep apnea.
The therapy device adapts ventilation automatically and continuously to the changing
requirements of the patient in question.
The SOMNOvent C R i s not suitable for life-support use on patients requiring ventilation.
Caution!
To ensure successful therapy with the SOMNOvent CR, the pressure limits prescribed
by the doctor and the background ventilation frequency must be determined and
adjusted accordingly in a sleep laboratory.
2.2 Description of function
The SOMNOvent CR has an electronically-controlled fan which takes in ambient air
through a filter and pumps it to the fan outlet. From here, the air flows through the tube
system and the breathing mask to the patient.
The SOMNOvent CR analyzes the pressure in the mask and the air flow to the patient and
detects from this sleep-related respiratory disorders such as Cheyne-Stokes breathing or
airway obstructions.
Depending on the events detected, the three pressure levels IPAP (pressure during
inspiration), EPAP (pressure at the start of exhalation) and EEPAP (pressure at the end of
exhalation) are automatically adapted to the current requirements of the patient.
• If respiratory volume drops, the device supports the patient's breathing
by continuously increasing IPAP/EPAP difference. In this way, ventilation
in Cheyne-Stokes breathing and in central or mixed sleep apnea
syndrome is normalized.

10 Description of device
EN
• In the case of apneas, the therapy device ventilates at a fixed respiratory
frequency or automatically at an individual frequency
• In the case of increasing respiratory volume, the IPAP/EPAP difference is
reduced to calm breathing.
• If obstructions (epochs with apneas, hypopneas, flow limitations or
snoring) are detected, EEPAP is increased to keep the airways open.
• In the case of normal breathing, pleasant exhalation relief is
administered. Before the transition to exhalation, therapy pressure is
reduced to relieve exhalation. This increases patient comfort. Before the
start of the next inspiration, pressure is increased back up to therapy
pressure. Pressure is slightly increased during inspiration.
The device stores data relating to therapy monitoring and adjustment, thus allowing
comprehensive analysis by the doctor.
Automatic Softstart is fitted to facilitate falling asleep. On switching on, pressure is reduced
to the Softstart pressure set by the doctor. Therapy pressure then slowly increases to the
specified value. The device does not react to respiratory disorders during the Softstart
phase.
The therapy device can be used to check whether the mask is correctly fitted. Leaks due to
a poorly-fitted mask often only occur at relatively high pressures. To check that the mask
is leaktight, it is possible to output a higher pressure during the first 30 seconds after the
therapy device is switched on. This pressure is adjustable.
A qualitative leakage display is available during therapy.
It is possible to activate automatic on/off on the SOMNOvent CR. The device can be
switched on by taking a breath into the mask and switches off automatically if not used.
If the power supply is interrupted and then restored, the SOMNOvent CR is in the condition
in which it was before the interruption. Stored data are retained.
