Newborn children receiving highly concentra-
ted (more than 40%)
oxygen treatments for longer periods of time
can suffer from lesions to the eyelenses that can
cause blindness (retrolenticular fibroplasia).
Apart from that there is danger that bleedings(
pulmonial hemorrhage), cellular and/or functio-
nal disorders of the lungs (focal atelectasis as well
as hyalin membrane lesions with diffuse pulmo-
nary fibrosis) occur.
In order to prevent such a collapse of the lung
functions (bronchopulmonial dysplasia), it is im-
perative to check the oxygen pressure in the arte-
rial (oxygen-rich) blood repeatedly.
1.2. Functional Characteristics
By means of a set pressure reducer the oxygen
pressure from the bottle (200 bar) is reduced to a
working pressure of 1.6 bar ± 0.2 bar.
The oxygen is led through a spiral hose from
the pressure reducer to the Precise 3000 . The
user is connected to the Precise 3000 by a nasal
canula.
A micro-controler built into the
Precise
3000
regulates the oxygen flow to the user accor-
ding to two operating modes and sixteen perfor-
mance steps. The functions of the
Precise 3000
are permanently monitored during use.
The Precise 3000 only releases the oxygen at
the beginning of the inhalation for a certain peri-
od of time. Only that oxygen can reach the alveo-
li and be absorbed by the blood in this way.
Most of the remaining oxygen would be exha-
led again.
The Precise 3000 can be set to the user’s in-
dividual needs by a medical expert.
The user himself can choose beteween 16 per-
formance steps according to the respective requi-
rements.
The user must inhale through the nose to make
sure the
Precise 3000
can serve properly.
If the device does not receive an inhalation im-
pulse during one minute an acoustic alarmsignal
is set off and
CHECK NASAL CANULA ap-
pears in the display. If this error is not eliminated
the device turns off automatically (see point 3.6).
1.3. Safety Instructions
This technical maunual and the instructions for
use are part of the unit supplied. It must be avai-
lable at any time.
Precondition to the agreed use of the Precise
3000
is thorough knowledge and adherance to
these instructions for use.
The instructions given here serve, following
the device safety laws, the prevention of dangers
by using the device in a not agreed manner and
have to be read and observed by all those who use,
check and maintain the device.
Do not expose the oxygen bottle to any source
of heat (heating fan, radiator, oven etc.).
Only qualified service personnel may check the
apparatus in case of damages to the plug or mains
cable, malfunctioning, general damages from fal-
ling down onto the ground or into water.
Humidifyers must not be used.
Observe the important instructions for use.
Only original parts are to be used.
Remove battery when the device is not in use
for longer periods of time.
External electromagnetical interferance does
not endanger the user.
The connections are to be kept absolutely dry
and free of grease.
The oxygen bottle is to be protected against
falling over. Any damages to the device, the pres-
sure reducer as well as to the oxygen bottle are to
be reported to the authorized service personnel.
Keep the device and mountings free of oil and
grease (observe the instructions given by the the
oxygen supplier.
It is absolutely necessary to wash hands before
operating the device.
Smoking and open fire generally are strictly
prohibited near oxygen leading mountings!
Make sure the oxygen bottle is filled sufficient-
ly.
