6. Contents of the package and additional information

MEDICAL LINDE OXYGEN GAS is an inhalation gas thatbelongs to a group of medications known as medicinal gases. It is packaged in pressure bottles that contain only pure oxygen.

Oxygen is an essential element for the body and is administered to increase its levels in the blood and as a result achieve greater oxygen transport to all body tissues.

Oxygen treatment is indicated in the following cases:

• Correction of oxygen deficiency of various origins that require oxygen administration at normal or elevated pressure.
• Feeding of respirators in anesthesia - resuscitation.
• Administration via nebulizer of inhalation medications.

No useOXÍGENO MEDICINAL GAS LINDE:

This medication should not be used at high pressure in cases of untreated pulmonary collapses (untreated pneumothorax). A pulmonary collapse is an accumulation of gas in the thoracic cavity between the two pulmonary membranes. If you have had a pulmonary collapse previously, inform your doctor.

Be especially careful with OXÍGENO MEDICINAL GAS LINDE:

-If you suffer from a chronic lung disease such as bronchitis, emphysema, or asthma and in severe cases of oxygen deficiency. You should inform your doctor of this.

-Do not apply any fatty substances (vaseline, ointments, etc.) to the faces of patients due to the risk of inflammation (see Section 6).

-Because it can be toxic to the lungs or the nervous system depending on the concentration and the time it is applied (see Section 3 and Section 6).

Precautions for use

-Oxygen should not be used in the presence of flammable materials: oils, lubricants, fabrics, wood, paper, plastic materials, etc. (see Section 6).

-If oxygen is applied at high pressure (hyperbaric oxygen therapy) there may be injuries caused by the high pressure in the body cavities that contain air and are in communication with the outside. To avoid risks, compression and decompression should be slow (see Section 4).

-When using high-pressure oxygen therapy (hyperbaric oxygen therapy) you should inform your doctor in case of:

• Chronic obstructive pulmonary disease (COPD)
• A pulmonary alteration caused by the loss of elasticity of the lung tissue accompanied by severe respiratory difficulty (pulmonary emphysema)
• Upper respiratory tract infections
• Recent middle ear surgery
• Thoracic surgery, at any time in the patient's life
• Uncontrolled high fever
• Severe epilepsy
• Severe claustrophobia
• If you have had a pulmonary collapse previously: an accumulation of air or gas in the thoracic cavity between the two pulmonary membranes (pneumothorax)

Use in children

In newborns, especially if they are premature, there may be eye damage (retrolental fibroplasia) with certain oxygen concentrations (see Section 4).

Use of other medications and other forms of interaction

Inform your doctor or pharmacist if you are taking or have recently taken any other medications, including those obtained without a prescription.

• The toxicity of oxygen may be increased if used at the same time as other medications that also affect the lungs: corticosteroids, some cancer medications (bleomycin), sympathomimetics. It may also occur in the treatment of paraquat poisoning, when using X-rays, or in cases of hyperthyroidism or vitamin deficiencies C and E or glutathione deficiency.
• There have been reports of interaction with amiodarone. The recurrence of lung damage induced by bleomycin or actinomycin can be fatal.
• Oxygen can also worsen the respiratory depressions induced by alcohol.
• Among the medications known to produce adverse effects are: adriamycin, menadione, promazine, chlorpromazine, thioridazine, and chloroquine. The effects will be particularly pronounced in tissues with high oxygen levels, especially the lungs.

Pregnancy and lactation

Consult your doctor or pharmacist before using any medication

During pregnancy, the use of oxygen at normal pressure (normobaric oxygen therapy) in low concentrations is permitted.

During rescue treatments, oxygen can also be used during pregnancy at high concentrations and high pressures.

There are no contraindications for using oxygen during lactation periods.

Consult your doctor or pharmacist if you need advice before taking any medication.

Driving and using machines

There is no information on the effect of oxygen on driving and using machines, therefore you can drive but with extreme caution.

Follow exactly the oxygen administration instructions indicated by your doctor.

OXYGEN MEDICAL GAS LINDEis used by inhalation. The doctor will determine the correct dose of medical oxygen and administer it through an appropriate system for your needs that will ensure the supply of the correct amount of oxygen.

Dosage.The usual dose is:

• In patients who breathe spontaneously (spontaneous ventilation) and with acute respiratory failure, oxygen is administered at a flow rate of0.5 to 15 liters/minute. This may vary according to the results of the analyses performed (blood gas analysis).
• In patients who breathe spontaneously (spontaneous ventilation) and with chronic respiratory failure, oxygen is administered at a flow rate of0.5 to 2 liters/minute. This may vary according to the results of the analyses performed (blood gas analysis).
• In patients who require assistance with breathing (assisted ventilation), oxygen should be administered at a dose that allows achieving a minimum oxygen concentration of 21%, which can reach up to 100%.

Administration form

-In patients without ventilation problems: oxygen can be administered by spontaneous ventilation with the help of nasal glasses, a nasopharyngeal tube, or a mask, which should be adapted to the oxygen flow.

-In patients with ventilation problems, or who are anesthetized, oxygen is administered through special devices such as endotracheal tube, laryngeal mask, through a tracheotomy that allows connecting assisted ventilation, or others.

-Oxygen administration at high pressure (hyperbaric oxygen therapy) is performed in a hyperbaric chamber at a pressure of2 to 3 atmospheresand the duration of the sessions is between 90 minutes and 2 hours. These sessions can be repeated between 2 and 4 times a day depending on the indications and the clinical condition of the patient.

Treatment duration

As a general rule, high concentrations of oxygen should be used for the shortest time possible to achieve the desired result. The oxygen concentration administered should be reduced as soon as possible to the minimum necessary concentration.

• Oxygen concentrations up to 100% should not be given for more than 6 hours.
• Oxygen concentrations between 60-70% should not be given for more than 24 hours.
• Oxygen concentrations between 40-50% should not be given for the next 24 hours.
• Any oxygen concentration above 40% is potentially toxic after 2 days.

If you estimate that the action of OXYGEN MEDICAL GAS LINDEis too strong or too weak, inform your doctor.

Read carefully the usage instructions (see Section 6).

If you use more OXYGEN MEDICAL GAS LINDE than you should:

In some situations, too much oxygen can affect breathing and exceptionally cause anesthesia or unconsciousness due to carbon dioxide.

The toxic effects of oxygen vary according to the inhaled oxygen pressure and the duration of exposure.

At low pressure (from0.5 to 2.0 bars), these effects are more likely to occur in the pulmonary region than in the central nervous system (brain and spinal cord). At high pressure (hyperbaric oxygen therapy), the opposite occurs.

The effects in the pulmonary region include labored breathing (hypoventilation), coughing, and chest pain. The effects in the central nervous system include nausea, dizziness, anxiety, and confusion, to muscle spasms, loss of consciousness, and epileptic seizures.

If symptoms appear, contact your doctor or hospital or call the Toxicology Information Service, phone: 91 562 04 20.

In case of overdose, the mode of action is to reduce the inhaled oxygen concentration and symptomatic treatment is recommended.

Like all medications, MEDICAL LINDE GAS OXYGEN may cause adverse effects, although not everyone will experience them.

When oxygen is administered through nasal glasses, it may cause dryness of the nasal and labial mucosa.

Adverse effects typically appear when high concentrations of oxygen (above 70%) are used and after prolonged treatment (at least 6-12 hours).

Theinfrequent adverse effects, which may affect between 1 and 10 of every 1,000 patients, are:

- Respiratory, thoracic, and mediastinal disorders: atelectasis (alveolar lung collapse), dry cough, and respiratory-related pain.

- With high-pressure oxygen (hyperbaric oxygen therapy): disorders of the ear and labyrinth, such as a sensation of pressure in the middle ear and rupture of the tympanic membrane.

Therare adverse effects, which may affect between 1 and 10 of every 10,000 patients, are:

-Eye disorders: eye damage that may affect vision (retrolental fibroplasia) in premature newborns exposed to high oxygen concentrations.

Thevery rare adverse effects, which may affect fewer than 1 of every 10,000 patients, are:

- Respiratory, thoracic, and mediastinal disorders: severe difficulty breathing due to acute pulmonary failure (Acute Respiratory Distress Syndrome).

- With high-pressure oxygen (hyperbaric oxygen therapy): nervous system disorders, such as anxiety, confusion, loss of consciousness, and epileptic seizures.

Otheradverse effects reported and of unknown frequencyare:

- Apnea (respiratory interruption): in patients with chronic respiratory insufficiency.

- Nasal sinus injuries, pneumothorax (presence of air in the thoracic cavity), nausea, dizziness, temporary loss of vision, pain, and muscle contraction with high-pressure oxygen (hyperbaric oxygen therapy).

- Panic attacks: in patients subjected to high oxygen pressures in hyperbaric chambers

- Anemia.

- Affection of different organs with high oxygen concentrations in long-term treatments: heart (it may also decrease heart rate when administering 100% oxygen for short periods), liver, kidneys, and lungs (pulmonary fibrosis).

- Pulmonary malformations (bronchopulmonary dysplasia), hemorrhages in different locations (subependymal and intraventricular), and intestinal damage with tissue destruction (necrotizing enterocolitis) in newborns and premature babies.

If you consider that any of the adverse effects you are experiencing are severe or if you notice any adverse effect not mentioned in this prospectus, inform your doctor.

Instructions for use / handling

Do not smoke

Do not approach a flame

Do not lubricate

In particular:

• Never introduce this gas into an apparatus that is suspected to contain combustible materials, especially if they are greasy.

• Never clean with combustible products, especially if they are greasy, or the apparatus containing this gas or the valves, joints, seals, and closure devices.

• Never apply greasy substances (vaseline, ointments, etc.) to the patient's face.

• Do not use aerosols (lacquer, deodorant, etc.) or solvents (alcohol, perfume, etc.) on the material or nearby.

The OXÍGENO MEDICINAL containers are reserved exclusively for therapeutic use.

For the specific case of liquid oxygen, some additional product-specific precautions must be considered for its use and handling:

• Oxygen is a heavier gas than air, which can accumulate in low points after vaporization of the liquid and make the atmosphere hazardous.

• Oxygen at atmospheric pressure is a very low-temperature liquid (around -183°C) that can cause frostbite if it comes into contact with the skin upon splashing or handling the liquid without proper protective equipment.

• One liter of liquid oxygen releases 850 liters of gas by vaporization and warming to ambient temperature. The expansion of liquid oxygen by heating is 850 times its liquid volume, and therefore, precautions for overpressures in closed volumes (equipment and installations) and overoxygenation of materials and the atmosphere of the premises must be taken.

To avoid any incidents, the following instructions must be strictly respected:

1. Verify the good condition of the material before its use.

2. Verify at the time of delivery by the manufacturer that the bottle is equipped with an intact inviolability guarantee system.

3. Handle the material with clean and grease-free hands.

4. Use protective glasses and clean gloves intended for this use.

5. Do not touch the cold or frosty parts.

6. In case of cryogenic burns, rinse with plenty of water.

7. If the clothing becomes saturated with oxygen, move away from the oxygen liquid source and areas with fire hazards, and remove the clothing.

8. Ventilate, if possible, the use area, if it is a reduced location (vehicles, home)

9. Avoid exposure to heat sources or prolonged solar heating.

10. Open the valve gradually.

11. Close the valve of the container after its use.

12. Never force any part of the container and do not attempt to repair a faulty valve.

13. Never exceed the maximum service pressure.

14. Provide safety devices against overpressures in oxygen liquid circuits where there is a risk of liquid accumulation between two valves.

15. Group the containers and keep them in an upright position.

16. Use specific connections or flexible connection elements for oxygen.

17. Do not use intermediate connections to allow the connection of two devices that do not fit together.

18. In case of leakage, close the valve with a defect in tightness and check that the emergency device is activated. Do not use a container with leaks

19. Use only equipment specifically approved for this product and for the pressure and temperature of use.

20. Do not allow the backflow of substances into the container. Prevent water from entering the container.

This information is intended only for healthcare professionals:

The dosage depends on the patient's clinical condition. The oxygen dose should be adjusted according to the individual needs of each patient and taking into account the risk of oxygen intoxication.

Oxygen therapy aims to maintain a partial arterial oxygen pressure (PaO2) above 60 mm Hg (i.e., 7.96 kPa) or an arterial blood oxygen saturation above or equal to 90%,

If oxygen is administered diluted in another gas, its minimum concentration in the inspired air should be 21%, i.e., the inspired fraction (Fi O2) should be 21%, which can reach a concentration of 100%.

Warnings and precautions for use

• In certain severe cases of hypoxia, the therapeutic dose approaches the toxicity threshold. After 6 hours of exposure to an oxygen concentration of 100%, or after 24 hours of exposure to an oxygen concentration above 70%, pulmonary or neurological toxicity may appear.

• Important concentrations should be used for the shortest possible time and controlled by analyzing the arterial blood gases, at the same time as measuring the inhaled oxygen concentration; it is advisable to use, in any case, the smallest dose capable of maintaining the partial arterial oxygen pressure (Pa O2) at 50-60 mm Hg (i.e., 5.65-7.96 kPa) and, after 24 hours of exposure, try to maintain, as far as possible, an oxygen concentration below 45%.

• In neonates and premature babies, it is necessary to use the lowest possible concentration that has the desired effect to minimize the risk of eye damage, retrolental fibroplasia, or other possible unwanted effects. For infants who need an oxygen concentration (Fi O2) above 30%, the Pa O2 concentration should be regularly controlled to avoid exceeding 100 mmHg (i.e., 13.3 kPa) due to the risk of retinal alterations.

• Whenever oxygen is used, the increased risk of spontaneous ignition and fire must be taken into account. This risk increases when working with diathermy processes, defibrillation, and electroconversion therapies.
