Please read the entire instruction manual carefully prior
to initial operation to protect yourself and your patients
from operating errors! this instruction manual contains
instructions on checks which must be performed by the
practitioner before initial operation and periodically
thereafter. the checks are needed to ensure the unit and
its safety features are fully operational. Please keep this
instruction manual so that it can be consulted whenever
necessary.
Intended use
Specific percentages of medical nitrous oxide are added
to medical oxygen using the mixer. the patient remains
conscious, but is more relaxed and is no longer afraid of
the treatment. Various journals and studies have indi-
cated that nitrous oxide sedation up to a maximum of
70% nitrous oxide constitutes minimal sedation aimed
at achieving an anxiolytic effect (alleviating anxiety) in
patients. It is not an anaesthetic. the patient is awake
and breathing independently and can respond to exter-
nal stimuli. Some patients are not sufficiently sedated
with a level of 50% nitrous oxide. Accordingly, besides
the Baldus® touch 50, which can administer maximum
50% nitrous oxide, there are also the Baldus® touch 60
and 70 units, which are limited to maximum 60% and
70% nitrous oxide. trained practitioners can therefore
decide for themselves the maximum nitrous oxide dose
they would like to administer. the nitrous oxide concen-
tration is tailored to the individual patient. the Baldus®
touch 50, 60 and 70 units are designed for installation
in the Baldus® All-in-one-Cart, for example, or in plas-
terboard. the Baldus® Bag t is also compatible with ni-
trous oxide mixers from other manufacturers designed
for installation. Breathing bags and mask systems are
attached to the Bag t.
Important information
the oxygen-nitrous oxide mixer must not be combined
with anaesthetic equipment or used as anaesthetic
equipment. Adjusting the settings or system and open-
ing the mixer or Bag t are strictly forbidden, as this could
cause your patient serious harm. Any alterations to the
mixer or Bag t will invalidate all guarantees and warran-
ties.
only accessories approved by Baldus® for the system
may be used. In case of faults or problems discontinue
the treatment with nitrous oxide immediately and con-
sult your instruction manual and/or contact your ser-
vice partner or the manufacturer Baldus medizintechnik
GmbH (0049 261/ 96 38 926-0). Do not attempt to per-
form any repairs yourself or adjust the mixer. never use
the unit without first taking an advanced training course
on how to handle and use these units. ensure to careful-
ly observe the content of the advanced training course
from which you obtained your certification and instruc-
tions from your service partner. the unit is only intended
for use in the medical field and may only be used by a
physician to sedate patients with nitrous oxide and ox-
ygen where necessary. the oxygen-nitrous oxide mixer
must not be used for any other purpose.
Please take the medical history correctly, as conveyed
during the advanced training course. At the start of the
treatment, apply the pulse oximeter and increase the
concentration of n
2
o slowly, according to the individual
patient, until the patient is sedated. never leave a sedat-
ed patient unattended! the breathing bag can be used
to monitor the sedation and should always be filled dur-
ing the sedation (can be ordered as an accessory, refer to
Section 4. Accessories and 7. Handling).
CautIon! Any sedation must always be monitored
using a pulse oximeter with individual alarm limits
(refer to Section 4. Accessories)! Always keep spare
batteries ready for the pulse oximeter!
Pulse oximeter
(can be ordered as an accessory, refer
to Section 4. Accessories): the pulse and oxygen satura-
tion level are vital parameters which indicate whether
the patient is doing well and the sedation is having an
effect. Sedation usually increases the oxygen saturation
level, lowers the pulse and relaxes the patient. If the ox-
ygen saturation level drops below an individually ad-
justable value, an alarm sounds on the pulse oximeter.
If a patient is being sedated with 20% nitrous oxide, for
example, 80% oxygen is being delivered. In other words,
the patient has a healthy oversupply of oxygen. If the
oxygen saturation level still falls below 85%, for exam-
ple, the nitrous oxide sedation must be stopped imme-
diately in case the nitrous oxide and oxygen have been
mixed up and 80% nitrous oxide is being delivered, for
instance. ensure the oxygen and nitrous oxide have not
been mixed up (refer to Section 6.1 General safety infor-
mation: gas type check).
Delivering 100% nitrous oxide would harm your patient.
However, there is very little probability of this happening
as the manufacturer performs a gas type check. If the pa-
