4. Clinical particulars
4.1 Therapeutic indications
Medicinal air is indicated as a replacement for normal environmental/room air whenever it is required,
e.g.:
-
In cases of respirator treatment or in connection with anaesthesia as a part of the fresh gas flow in order to give a gas mixture with the desired oxygen content (FiO2)
-
As propellant in nebulisation treatment
-
As pure air in the care of immunosuppressed patients such as in cases of organ/cell transplantation or extensive burn wounds.
4.2 Posology and method of administration
Method of administration
Medicinal air is administered via the inspiratory air.
Medicinal air is given via special equipment. With the aid of this equipment medicinal air is added to
the gas that is to be inspired, and on expiration the air that has not been absorbed is mixed with the
surrounding air (non-rebreathing system). In anaesthesia particularly, special equipment is often used
which allows a greater or lesser proportion of the exhaled gas to be recirculated in the respiratory
system and rebreathed (so-called rebreathing system).
For information on use and handling see section 6.6.
Dosage
The purpose of using medicinal air is to ensure reliable administration of gas which contains oxygen in
a concentration that corresponds to the normal air in the environment/room air without the risk of
mixing in odours or other potentially irritating substances. Medicinal air is only indicated as a
replacement/substitute for room air, and as soon as it is required it should be mixed with medicinal
oxygen so that the desired oxygen concentration is obtained, using the calculation:
FiO2 = [(number of litres of air/minute x 21) + (number of litres of oxygen/minute x 100] / (number of
litres of air/minute + number of litres of oxygen/minute).

5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Medical gases, ATC code V03AN05
Medicinal air contains 21 % oxygen and the remaining part is nitrogen gas, which must be considered
inert. Medicinal air is mainly used on account of its oxygen content, which corresponds completely to
room air.
Oxygen is vital for human life, and must be supplied continuously to all tissues in order to maintain the cells’ energy production. Its target is the mitochondria in the individual cells, where the oxygen takes part in an enzymatic chain reaction, which creates energy, aerobic metabolism.
Nitrogen may be considered as inert.
5.2 Pharmacokinetic properties
Medicinal air consists of 21 % oxygen, which corresponds completely to the concentration in normal
room air/surrounding air. It is administered by inhalation and it is transported via the airways to the
lungs. In the pulmonary alveoli, as a result of the difference in partial pressure, a gas exchange takes
place from the inspired air/gas mixture to the capillary blood. The oxygen is transported further with
the systemic circulation, for the most part bound to haemoglobin only a very small part is freely
dissolved in plasma, to the capillary beds in the different tissues of the body. The oxygen is
transported with the aid of the pressure gradient out to the various cells.
Oxygen that is absorbed in the body is excreted almost completely as carbon dioxide formed in the
intermediate metabolism.
Nitrogen is not absorbed. It follows the expiratory air without having undergone any
conversion/metabolism.

6.6 Special precautions for disposal and other handling
General
Medicinal gases must only be used for medical purposes.
Different gas types and gas qualities must be kept separate from each other. Full and empty gas
cylinders must be stored separately.
Never apply oil or grease, even if the cylinder valve is difficult to operate or if the regulator is difficult to connect.
Valves and equipment must be handled with clean and grease-free (hand cream, etc.) hands.
Use only standard equipment that is intended for medicinal air.
The gas cylinders must be protected from wind and weather, and kept dry and clean.
Check that the cylinders are sealed before use.
Remaining pressure at return should be > 2 bar (200 kPa).
Preparation for use
Remove the seal from the valve before use.
Use only regulators intended for medicinal air. Check that the connection on the outside of the
coupling or regulator is clean and that the connections are in good condition.
Replace O-ring/seal as recommended by the equipment manufacturer.
Never use a tool on a stuck pressure/flow regulator intended to be connected manually, as this
can damage the coupling.
Open the cylinder valve slowly – at least half a turn.
Check for leakage in accordance with the instruction that accompanies the regulator. Do not try to handle leakage from the valve or apparatus yourself other than by changing the gasket or O-ring.
In the event of leakage, close the valve and disconnect the regulator. Label defective cylinders, put them in the area intended for complaints and return them to the supplier.
Using the gas cylinder
Smoking and open fire are prohibited in areas where medicinal air is being used.
Shut the cylinder valve in the event of fire and when not being used.
Larger gas cylinders (> 5 L) should be transported with an appropriate type of cylinder trolley. Take special care that connected devices are not inadvertently loosened.
When the cylinder is in use it must be fixed to a suitable support preventing it from falling.
When a small amount of gas is left in the gas cylinder, the cylinder valve must be closed. It is
important to leave a little excess pressure in the cylinder to protect it from becoming contaminated.
After use, the cylinder valve must be closed hand-tight. Depressurise the regulator or connection.
