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 SOMNO
vent
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 SOMNO
vent
CR is in the condition
in which it was before the interruption. Stored data are retained.
