Explanations and
Safety Instructions
1.1. Use
The oxygen therapy with the breath-impulse con-
trolled
Precise 3000 is carried out exclusively
according to the current medical rules for the use
of medical oxygen. By using the
Precise 3000
a
multitude of possibilities in the oxygen therapy
open up to the user.
●
Mobility for the user
●
Considerably better use of the oxygen supply,
inter alia by automatic adaptation to the O
2
requirement
●
Decrease in dessication of the air passages du-
ring oxygen inhalation
●
Increase of the volume percentage of oxygen in
the air
●
Best adaptation to the oxygen requirement
even during the user’s changing performance
levels
Latest technical- and manufacturing standards
guarantee perfect functioning, high flexibility
and utmost user comfort.
Only for patients whose lifefunctions are not
directly and permanently dependent on a higher
oxygen concentration in the air.
The oxygen inhalation therapy, however,
should only be carried out after thorough exami-
nation by a physician.
Oxygen for medical purposes is a highly effec-
tive drug. Wrong application might cause side ef-
fects.
The instructions of the physician are to be
strictly observed.
Every physical disorder has to be reported to
the physician in attendance immediately.
Contraindications
An oxygen therapy can only be carried out taking
special care in the following cases:
– patients of high age
– obesity
– simultaneous ACTH- or glucocorticoid-treat-
ment
– patients with high carbon dioxid concentration
in arterial (oxygenrich) blood
– poisoning with substances that reduce brea-
thing.
– breathing control disorders in the central ner-
vous system
– fever
The application of a pure oxygen treatment
should not be carried out in case of acute trouble
in breathing (respiratory insufficiency on the base
of a chronic obstructive emphysema bronchitis)
because of the impending decrease in ventilation
of the lungs.
Side effects
Taking into consideration the contraindications,
side effects under normal oxygen pressure are not
to be expected. Patients suffering from insuffi-
cient lung ventilation might encounter a rapid in-
crease of the carbon dioxid value inhaling oxygen.
No clinically significant symptoms have been
diagnosed during treatments with 50% oxygen
for up to seven days. 100% oxygen given for 24
hours, however, leads to cellular and functional le-
sions of the lungs (cell changes of the respiratory
epithelium, secretion inspissation, restriction of
ciliar movement, atelectasis as well as changes of
the minute volume, carbon dioxide dretension
and pulmonial vasodilation)
This means that generally during treatments
carried out over longer periods of time at 1 at-
mosperic excess pressure or at even higher oxygen
pressures in the air, symptoms of poisoning (hy-
poventilation, acidosis up to development of an
edema of the lungs) are to be expected.
It is to be observed that decreasing the partial
pressure too rapidly can lead to a critically insuf-
ficient oxygen supply (hypoxemia).
