2. Description of device
2.1 Intended use for VENTImotion/VENTIlogic
VENTImotion and VENTIlogic are home ventilation
devices for the non-invasive, non-life support venti-
lation of adult patients with respiratory insufficiency
in whom there is evidence of autonomous respira-
tory drive. This corresponds to the following clini-
cal pictures:
•
restrictive and obstructive ventilation disorders
like paresis of the diaphragm, OSAS, COPD
2.2 Functional description
Provision of therapy pressure
An electronically-controlled fan draws in ambient
air through a filter and delivers it to the device out-
let. From here, the air flows through the hose sys-
tem and the mask to the patient.
Therapy modes
The device can be operated in the following ther-
apy modes: CPAP, S, ST, T, SX, SXX, TA (TA with
VENTIlogic only).
In time-controlled mode T and in assisted-controlled
mode ST, your doctor can set respiratory frequency
in the range from 6 to 45 breaths per minute and
inspiration time in the range from 20 % to 67 % of
the respiratory period.
In assisted modes S, SX and SXX and in assisted-
controlled mode ST, your doctor can select one of
6 trigger levels for both inspiration and exhalation.
Your doctor can switch off the trigger for exhala-
tion. Exhalation is then time-controlled.
Other functions
The Softstart function makes it easier to fall asleep.
Your doctor sets initial pressures for inspiration and
exhalation which continuously rise to the therapy
pressures during the Softstart phase. This function
can be disabled by the doctor.
The therapy device has an auto switch-on system.
If this is activated, the device can be switched on

Description of device
•
disorders of the respiratory mechanism like
scoliosis, deformity of the thorax
•
neurological, muscular and neuromuscular dis-
orders
•
central respiratory regulation disorders
VENTImotion and VENTIlogic are
life-support use.
Use the device only for the purpose described
here.
Sensors detect the pressure in the mask and in the
hose system and also the respiratory phase switch
(trigger point). The fan accordingly provides the
IPAP and EPAP pressures set by the doctor.
In the adaptive, controlled TA mode, the device
automatically adapts to your personal breathing
rhythm and supplies the therapy pressure in exactly
the same rhythm.
If no breath is taken into the device in S mode,
pressure is switched at a minimum frequency of
6 breaths per minute.
You can activate volume compensation. Minimum
volume and maximum pressure rise are set for this
purpose. If the minimum volume is undershot, the
device automatically increases pressure continu-
ously until the set maximum pressure (therapy pres-
sure + max. pressure rise) is reached.
by a breath being taken into the mask. The device
is still switched off using the on/off key
The display shows therapy mode and, depending
on mode, the values currently being applied for
CPAP/IPAP and EPAP and for respiratory frequen-
cy (f). Spontaneous or mechanical respiratory
phase switches are also displayed and the pres-
sure change shown in the form of a graph.
