1. What Oxígeno Medicinal Líquido Oximesa is and what it is used for

Oxígeno Medicinal Líquido Oximesa 99.5% v/v, gas for inhalation, is an inhalation gas supplied in portable cryogenic containers made of stainless steel with various capacities.

It contains oxygen at a concentration higher than 99.5% v/v.

It contains no other excipients.

Oxygen is an essential element for the body.

Oxygen therapy is indicated in the following cases:

• Correction of oxygen deficiency of various origins requiring administration of oxygen at normal or increased pressure.
• Supplying anaesthesia and resuscitation respirators.
• Administration via inhalation nebulizer of inhaled medications.

Treatment of acute attacks of cluster headache (a specific type of headache causing short but very severe episodes on one side of the head).

2. What you need to know before using Oximesa Liquid Medicinal Oxygen

Do not use Oximesa Liquid Medicinal Oxygen

This medicinal product must not be used under high pressure in cases of untreated lung collapse (untreated pneumothorax). A lung collapse is an accumulation of gas in the pleural cavity between the two lung membranes. If you have previously experienced a lung collapse.

Warnings and precautions:

Consult your doctor, pharmacist, or nurse before starting to use Oximesa Liquid Medicinal Oxygen.

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

Do not apply any greasy substances (e.g. petroleum jelly, ointments, etc.) to the face, due to the risk of inflammation with this medicinal product (see section 6).

In certain severe cases of oxygen deficiency, pulmonary or neurological toxicity may occur after 6 hours of exposure to 100% oxygen concentration, or after 24 hours of exposure to oxygen concentrations above 70% (see sections 3 and 6). Therefore, high oxygen concentrations should be used for the shortest possible time and monitored by arterial blood gas analysis, while simultaneously measuring the concentration of inhaled oxygen. It is advisable to use the lowest effective dose capable of maintaining arterial partial pressure of oxygen (PaO₂) at 50–60 mm Hg (i.e., 5.65–7.96 kPa). After 24 hours of exposure, it is recommended, whenever possible, to maintain an oxygen concentration below 45%.

Oxygen is not a substitute for other prescribed medications for the treatment of cluster headache.

Precautions for use:

• This medicinal product must not be used in the presence of flammable materials: oils, lubricants, fabrics, wood, paper, plastic materials (see section 6).

• When oxygen is administered under high pressure (hyperbaric oxygen therapy), injuries may occur in body cavities containing air and communicating with the outside; therefore, compression and decompression must be performed slowly (see section 4).

• If you are to receive high-pressure oxygen therapy (hyperbaric oxygen therapy), you must inform your doctor if any of the following apply:

  • You have COPD (chronic obstructive pulmonary disease).
  • You have a pulmonary disorder caused by loss of elasticity in lung tissue, accompanied by severe respiratory difficulty (pulmonary emphysema).
  • You have an upper respiratory tract infection.
  • You have recently undergone middle ear surgery.
  • You have previously undergone thoracic surgery.
  • You have uncontrolled high fever.
  • You suffer from severe epilepsy.
  • You have a fear of enclosed spaces (claustrophobia).
  • You have previously experienced a lung collapse (accumulation of air or gas in the pleural cavity between the two lung membranes (pneumothorax)).

Children:

In newborns, especially premature infants, certain oxygen concentrations may cause eye damage (retrolental fibroplasia).

For infants requiring oxygen concentrations above 30%, arterial partial pressure of oxygen (PaO₂) must be monitored regularly to ensure it does not exceed 100 mm Hg (i.e., 13.3 kPa).

Use of Oximesa Liquid Medicinal Oxygen with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Oxygen toxicity may be increased by corticosteroids, certain anticancer drugs, paraquat, sympathomimetics, X-rays, or in cases of hyperthyroidism or deficiency of vitamins C and E or glutathione deficiency.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.

This medicinal product has been widely used without any notable adverse effects.

Driving and use of machines

There are no data available regarding the effects of Oximesa Liquid Medicinal Oxygen on driving or operating machinery.

3. How to use Oximesa Liquid Medicinal Oxygen

Follow exactly the administration instructions for this medicine as indicated by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

Your doctor will determine the correct dose of Oximesa Liquid Medicinal Oxygen and will administer it using a system appropriate to your needs, which will ensure delivery of the correct amount of oxygen.

If you feel that the effect of Oximesa Liquid Medicinal Oxygen is too strong or too weak, inform your doctor.

If you use more Oximesa Liquid Medicinal Oxygen than you should:

In case of overdose or accidental ingestion, immediately contact your doctor or pharmacist, or call the Toxicology Information Service at telephone number 91 562 04 20, indicating the medicine and the amount ingested.

In case of overdose, the concentration of inhaled oxygen should be reduced and symptomatic treatment is recommended.

4. Possible adverse effects

Like all medicines, Oximesa Medicinal Liquid Oxygen may cause adverse effects, although not everyone experiences them.

In particular, in chronic respiratory failure, there is a possibility of apnea occurring.

Inhalation of high concentrations of oxygen may cause minor lung collapse.

Administration of oxygen at high pressures may cause injury to the inner ear (potentially leading to rupture of the tympanic membrane), sinuses, and lungs (potentially leading to pneumothorax).

Seizure episodes have been reported following administration of 100% oxygen concentration for more than 6 hours, particularly when administered under high pressure.

Lung injury may occur after administration of oxygen concentrations exceeding 80%.

Patients undergoing high-pressure oxygen therapy in chambers may experience claustrophobia episodes.

Other adverse effects in children

In newborns, especially if premature, exposed to high oxygen concentrations (FiO2 >40%; PaO2 above 80 mm Hg (i.e., 10.64 kPa)) or for prolonged periods (more than 10 days at FiO2 > 30%), there is a risk of retinopathy, appearing between 3 and 6 weeks after treatment. This may regress spontaneously or lead to retinal detachment or even permanent blindness.

If you experience any adverse effects, consult your doctor, pharmacist, or nurse, even if they are adverse effects not listed in this leaflet.

Detailed information on this medicinal product is available on the website of the Spanish Agency of Medicines and Health Products (AEMPS): http://www.aemps.gob.es.

This information is intended exclusively for healthcare professionals.

Instructions for use/handling

Do not smoke.
Do not bring near flames.
Do not grease.

For liquid oxygen specifically, additional product characteristics must be considered as precautions for its use and handling:

• Oxygen is a gas heavier than air, which may accumulate in low-lying areas after vaporization of the liquid, creating a hazardous atmosphere.
• At atmospheric pressure, oxygen is a liquid at a very low temperature (approximately -183°C), and contact with skin may cause cryogenic burns in case of splashing or handling the liquid without appropriate protective equipment.
• One liter of liquid oxygen expands to 850 liters of gas upon vaporization and warming to room temperature. The expansion ratio of liquid oxygen upon warming is 850 times its liquid volume; therefore, appropriate precautions must be taken to prevent overpressure in closed volumes (equipment and installations) and over-oxygenation of materials and the atmosphere in enclosed spaces.

Medical oxygen containers are reserved exclusively for therapeutic use.

To prevent any incidents, the following instructions must be strictly observed:

• Never introduce this gas into any device suspected of containing combustible materials, especially those of a greasy nature.
• Never clean devices containing this gas, taps, seals, gaskets, closure devices, or valves with flammable products, especially greasy substances.
• Do not apply any greasy substances (vaseline, ointments, etc.) to the patient's face.
• Do not use aerosols (hairspray, deodorants, etc.) or solvents (alcohol, perfume, etc.) on or near the equipment.
• Avoid exposure to heat sources (stoves, radiators, fireplaces, etc.) or prolonged solar heating.
• Ventilate the area of use whenever possible, especially in confined spaces (vehicles, homes).
• Check the equipment is in good condition before use.
• At the time of delivery by the manufacturer, verify that the container is equipped with an intact tamper-evident seal.
• Handle the equipment with clean, grease-free hands.
• When handling cryogenic containers, use the specified personal protective equipment (goggles or face shields, clean gloves designated for this purpose, appropriate clothing, etc.) and follow the instructions and precautions described for the operation.
• Store containers grouped together and in an upright position.
• Use oxygen-specific connections or flexible connecting elements.
• Use only equipment specifically approved for this product and for the intended pressure and temperature conditions.
• Install overpressure safety devices in each section of the circuit where residual liquid oxygen may remain trapped between two valves.
• Never touch cold or frozen parts of the equipment.
• Do not use intermediate adapters to connect two devices that do not fit together.
• Small cryogenic containers (Stationary Units) or their auxiliary equipment (Portable Units or backpacks) may be fitted with accessory use components (humidifier bottle, flowmeter, mask, or nasal cannula, etc.). These devices must be used according to prescription conditions (flow rates, dosages, etc.).
• Open valves slowly and close them when the product is not in use.
• Never force any part of the cryogenic container or attempt to repair faulty valves; in case of problems, contact the supplier.
• Never use a container that is leaking.
• If clothing becomes saturated with oxygen, move away from the source of liquid oxygen and from areas with fire hazards. Remove the clothing immediately.
• In case of cryogenic burn, rinse thoroughly with water.
• Prevent backflow of substances into the container. Prevent water from entering the container.

Do not leave the equipment valve open when not in use.
