tient’s pulse is too high, this may indicate oversedation
(refer to Section 2). An alarm sounds to alert the practi-
tioner. In case of oversedation, reduce the nitrous oxide
immediately or set it to 0 and administer 100% oxygen
to the patient. If the oxygen saturation level indicated on
the pulse oximeter falls while 100% oxygen is being ad-
ministered, switch the unit off immediately and contact
your service partner. If the pulse is too low and the pa-
tient is too deeply sedated, an alarm signal also sounds
and the nitrous oxide must be reduced. It is essential
that information learned during the advanced training
course be adhered to!
Information on ambient air pollution
with nitrous oxide
the practising physician is responsible for ensuring the
rooms used are sufficiently ventilated and for complying
with the limit values for nitrous oxide concentration in
rooms. observe the current technical rules for Hazard-
ous Substances trGS 900 (occupational exposure limit
values) and trGS 525 (Hazardous substances in health
care facilities). take the table under Section 6 on reduc-
ing ambient air pollution through nitrous oxide into ac-
count.
A suction unit is compulsory and should have a
suction power of at least 45 l/min.! It must be moni-
tored using a vacuum control block (refer to Section
4. Accessories)!
Vacuum control block (can be ordered as an accessory,
refer to Section 4. Baldus® scavenger system accesso-
ries and instruction manual): the vacuum control block
is equipped with an inspection glass with indicator and
ball and a controller. the controller is used to adjust the
suction power. the suction unit is at the ideal setting
when the ball is in the indicated range.
Environment and disposal
the mixer and Bag t must be positioned in a splash-
proof area. If moisture or other contaminants enter the
unit a malfunction may occur. the unit must be stored at
a temperature between -5°C and 48°C (stabilise to room
temperature before operation). return the unit to us for
disposal or observe the usual disposal methods.
CautIon! It may be difficult to read the display
in bright environments, e.g. if a lamp or the sun is
shining directly on it. ensure that the percentages are
set correctly, as incorrect settings may lead to overse-
dation, for example.
