SUMMARY OF PRODUCT CHARACTERISTICS
1 NAME OF THE MEDICINAL PRODUCT
Medicinal Air Synthetic 21.75% v/v medicinal gas compressed.
2 QUALITATIVE AND QUANTITATIVE COMPOSITION
Oxygen 21.75% v/v.
For the full list of excipients, see section 6.1.
3 PHARMACEUTICAL FORM
Medicinal gas, compressed
Medicinal Air Synthetic is a colourless, odourless and tasteless gas.
4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Prevention of hypoxia where treatment with atmospheric air is indicated.
4.2 Posology and method of administration
Posology
The flow rate and duration of administration should be determined based on the cause of the hypoxia.
Method of administration
A physician, experienced in intensive care or pneumology, should see to the administration of medicinal air as inlet gas for respirators used in respiratory support.
For long-term administration, humidification is advised.
Medicinal air is administered via inhaled air, preferably by means of dedicated equipment (for example, a nasal cannula, facial mask, facial tent, an oxygen tent over a crib, or flow to tracheotomy). Such devices must be used according to the instructions of the manufacturer. Through this equipment, medicinal air is administered along with inhaled air. Upon exhaling, the exhaled gas leaves the patient together with any surplus air and mixes with the ambient air (“non-rebreathing” system).
If the patient is not able to breathe independently, artificial breathing support can be provided.
General
Connections for tubes, valves, etc., must be clean and dry. If needed, clean them according to the instructions of the supplier. Do not use solvents.
Do not use oil or grease on the cylinder valve or the related equipment.
4.3 Contraindications
There are no absolute contraindications.
4.4 Special warnings and precautions for use
Medicinal air may only be administered to patients under atmospheric pressure.
Administration of medicinal air under pressure could cause decompression sickness (as a result of the effects of nitrogen) and oxygen toxicity.
If medicinal air is mixed with other inhalation gases, the oxygen fraction in the inhaled mixture (Fraction of inspired oxygen - FiO2) must be kept at least at 21% v/v. Practically speaking, this means that if it is a component of a gaseous mixture, oxygen must be one of the other components.
At extremely high flow rates, such as in an incubator, medicinal air may feel cold.
Medicinal air should not be used where higher than atmospheric concentrations of oxygen (>21%) would be indicated.
Paediatric population
Children differ from adults, in more ways than just in size: they have, for example, a different breathing pattern, tidal volume and geometry of the airways. Caution is needed in relation to the use in children.
4.5 Interaction with other medicinal products and other forms of interaction
There have been no reports of interactions with medicinal air.
The interactions with 100% v/v oxygen are listed below. It is not known whether these also pertain to medicinal air (oxygen 21.75 % v/v).
There have been reports of interaction between oxygen and amiodarone. Relapse of pulmonary damage induced by bleomycin or actinomycin may be fatal. In patients with pre-existing lung damage induced by oxygen radicals, this damage could be made worse by oxygen therapy, e.g., during treatment for paraquat poisoning.
Respiratory depression as a consequence of alcohol can be made worse by oxygen. Medicines known to cause undesirable interactions are adriamycin, menadione, promazine, chlorpromazine, thioridazine and chloroquine. In tissues with a high oxygen concentration, especially the lungs, this effect will be stronger. The toxicity of oxygen may be intensified by corticosteroids, sympathicomimetics and roentgen rays. Furthermore, the toxicity of oxygen can be increased by hyperthyroidism, vitamin C or E deficiency, or glutathione.
4.6
Fertility, pregnancy and lactation
Medicinal air may be used during pregnancy and breastfeeding.
4.7 Effects on ability to drive and use machines
Medicinal air has no influence on the ability to drive and use machines.
4.8 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:

5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Medical gases, ATC code: V03AN05.
Pharmacodynamic effects
The active ingredient, oxygen, is an essential element for sustaining life. The pharmacodynamic elements of medicinal air are linked to the physiological respiration.
Air contains approximately 21% oxygen, equivalent to (at normal atmospheric pressure) a partial pressure of 159 mmHg. The purpose of physiological respiration is to maintain an oxygen supply sufficient enough to comply with the metabolic demands of tissues.
5.2 Pharmacokinetic properties
Inhaled oxygen is absorbed by pressure-dependent gas exchange between alveolar gas and the capillary blood passing the alveoli. Oxygen (mainly bound to haemoglobin) is transported to all body tissues via the systemic circulation. Only a very small fraction of it is free oxygen (dissolved in plasma). Oxygen is an essential component in the intermediary metabolism of the cell for the formation of energy-aerobic ATP production in the mitochondria. The oxygen absorbed by the body is almost completely eliminated as carbon dioxide, which is formed during this intermediate mechanism.
5.3 Preclinical safety data
Since this product is virtually equivalent to ambient air, no specific risks are to be expected for human health.

6.3 Shelf life

6.4 Special precautions for storage
- The gas cylinders should be stored between -20°C and +65°C.
- The gas cylinders should be stored vertically, except gas cylinders with a convex bottom; these should be stored horizontally, or in a crate.
- The gas cylinders should be protected from falling or from jolts, for example, by implementing the following precautions: securing the gas cylinders or placing them in a crate.
- The gas cylinders should be stored in a well-ventilated room that is exclusively used for the storage of medicinal gases. This storage room must not contain any inflammable materials.
- Gas cylinders containing a different kind of gas, or a gas that has a different composition, should be stored separately.
- Full and empty gas cylinders should be stored separately.
- The gas cylinders must not be stored in the vicinity of sources of heat.
- Gas cylinders must be stored covered and protected against the effects of the weather.
- Close the valves of the cylinders after use.
- Return cylinder to the supplier when empty.
6.5 Nature and contents of container
Medicinal air is packaged in gas cylinders in a gaseous state and under the pressure of
200 bar (at 15°C). The cylinders are made of steel or aluminium. The valves are made
of brass, steel or aluminium.
Gas cylinders with a content of (x) litres deliver (y) litres of air at 15°C and 1 bar.
