Clinical Particulars
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.
Medicinal air is indicated in children, adults and elderly.
Posology and method of administration
Posology
Medicinal air can be used in children, adults and elderly. 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)
Peadiatric population
Medicinal air is indicated in children of all ages.
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.
Contraindications
None known.
Special warnings and precautions for use
None known.
Interaction with other medicinal products and other forms of interaction
No known interactions.
Fertility, pregnancy and lactation
Medicinal air may be used during pregnancy and lactation. Medicinal air does not affect fertility.
Effects on ability to drive and use machines
Not relevant.
Undesirable effects
No undesirable effects are known.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V*.
Overdose
Not relevant.
Pharmacological Properties
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 continually 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.
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.

Special precautions for disposal and other handling
Instructions for use and 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 use oil or grease, even if the cylinder valve is stiff or if the regulator is difficult to connect. Handle valves and equipment to match with clean and grease-free (hand cream, etc.) hands.
Use only standard equipment that is intended for medicinal air.
The gas cylinders must be stored protected from wind and weather, and kept dry and clean.
Check that the cylinders are sealed before use.
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.
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 deal with 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 uncouple the regulator. Label defective cylinders, put in the place intended for complaints and return them to the supplier.
Cylinders equipped with the so called LIV valve have the pressure regulator incorporated in the valve. A separate pressure regulator is therefore not needed. The LIV valve has a standard quick connector to be used with specific devices, and if provided a separate outlet with adjustable administration flow.
Using the gas cylinder
Smoking and open flames are forbidden in rooms where medicinal air is being used. Close down the apparatus in the event of fire or if it is not being used.
Larger gas cylinders should be transported with an appropriate type of cylinder cart. Be especially careful that connected apparatus is not inadvertently loosened.
When the cylinder is in use it must be fixed in a suitable support.
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 pressure in the cylinder to protect it from contamination.
After use, the cylinder valve must be closed hand-tight. Depressurise the regulator or connection.
