Intended purpose
The LAVI ventilator device may only be used for non-life-supporting respiration. It serves
as intermittent respiration support as well as to provide respiration to patients with
insufficient spontaneous breathing ability. The device is suitable for adults and chil-
dren from a tidal volume of 100 ml and higher and is designed for home care and/or
use in professional health care facilities. It must not be used for intensive ventilation.
LAVI is not intended for use in vehicles, planes or helicopters.
Description of function
The blower sucks in the ambient air via a filter and transports it to the patient at a set
pressure via a leakage tube circuit (with passive exhalation valve). Ventilation can be
invasive (e.g. using a tracheostoma) or non-invasive (using a mask).
Ventilation is carried out according to ventilation parameters set using the control ele-
ments. Ventilation can be monitored based on measurements and graphs on the display.
In case the custom and permanent alarm parameters are violated, visual and acoustic
alarms are emitted. If the prescribed ventilation is no longer possible due to a techni-
cal error, an acoustic alarm is emitted for at least 2 minutes.
If LAVI is operated with an internal battery, ventilation can continue on without dis-
ruption in the event of a power failure.
LAVI can be connected to a low-pressure source of oxygen for ventilation with increased
oxygen concentration. When oxygen is introduced but ventilation is not started, the
oxygen supply is interrupted by a safety valve. Remaining oxygen can be released from
the device via the oxygen outlet.
It is also possible to combine LAVI with the integrable humidifier “AquaTREND uni” or
an external humidifier.
Therapy and statistical data, including alarms and events, can be copied onto an SD
card and analysed using the PC software “easySET”.
For service purposes, LAVI features one USB and one COM interface.
