2. Description of device
2.1 Intended use
SOMNOvent a u t o - S
SOMNOvent auto-S is an automatically-regulating BiLevel S therapy device with
autoTriLevel principle and up to three pressure levels suitable for treating patients from the
age of 12 with obstructive, mixed or complex sleep apnea and
– a high pressure requirement,
– poor compliance due to high pressure on exhalation,
– fluctuating pressure requirement or
– nocturnal hypoventilation (OHS).
SOMNOvent auto-S is not suitable for life-support purposes on patients requiring
ventilation.
Note
To ensure successful therapy with SOMNOvent auto-S, it is important to determine and
set accordingly therapy mode, pressure limits and minimum respiratory frequency.
SOMNOvent a u t o - S T
SOMNOvent auto-ST is an automatically-regulating BiLevel ST therapy device with
autoTriLevel principle and up to three pressure levels suitable for treating patients from the
age of 12 with obstructive, mixed or complex sleep apnea and
– a high pressure requirement,
– poor compliance due to high pressure on exhalation,
– fluctuating pressure requirement,
– central apneas,
– nocturnal hypoventilation (OHS),
– respiratory insufficiency or
– coprevalent COPD (overlap).
SOMNOvent auto-ST is not suitable for life-support purposes on patients requiring
ventilation.

10 Description of device
Note
To ensure successful therapy with SOMNOvent auto-ST, therapy mode, therapy objective
and possibly other therapy parameters have to be determined and set accordingly by spe-
cialist medical staff.
2.2 Description of function
The therapy device has an electronically-controlled fan which draws in ambient air through
a filter and pumps it to the fan outlet. The air flows to the patient from here through the
breathing tube and the breathing mask.
The therapy device analyzes the pressure in the mask and the air flow to the patient and
from this, detects sleep-related respiratory disorders such as obstructions of the airways or
a central respiratory deficit.
The three pressure levels IPAP (pressure during inspiration), EPAP (pressure at the start of
exhalation) and EEPAP (pressure at the end of exhalation) are adapted to suit the patient’s
current requirements depending on the events detected.
The therapy device has different modes:
•CPAP
•S: one of three pressure variants can be selected for S mode.
•BiLevel: IPAP and EPAP can be set to a fixed value
•TriLevel: IPAP, EPAP and EEPAP can be set to a fixed value.
•auto TriLevel: IPAP, EPAP and EEPAP are continuously adapted to the
patient’s current requirements.
In the event of obstructions, EEPAP is automatically increased within lim-
its which can be set; if there are no obstructions, it is gradually reduced
again.
The difference between IPAP and EPAP (PDIFF) can likewise be adapted
automatically up to an upper limit which can be set.
•ST (can only be selected on SOMNOvent auto-ST): one of three pressure variants can be
selected for S mode:
•BiLevel: IPAP and EPAP can be set to a fixed value.
•TriLevel: IPAP, EPAP and EEPAP can be set to a fixed value.
•auto TriLevel: IPAP, EPAP and EEPAP are continuously adapted to the
patient’s current requirements.
In the event of obstructions, EEPAP is automatically increased within lim-
its which can be set; if there are no obstructions, it is gradually reduced
again.
