1. What Ossigeno Air Liquide Sanità is and what it is used for
Ossigeno Air Liquide Sanità contains oxygen, a gas naturally present in the air we breathe.
Medical oxygen increases the amount of oxygen in the blood and its distribution to all body tissues.
Ossigeno Air Liquide Sanità is indicated in patients of all ages:
- for the treatment of acute and chronic respiratory failure,
- for use in anaesthesia,
- in intensive care,
- in hyperbaric chambers, which are rooms where air pressure is higher than atmospheric pressure.
2. What you should know before being administered Ossigeno Air Liquide Sanità
Normobaric oxygen therapy
There are no absolute contraindications.
Hyperbaric oxygen therapy (oxygen at a pressure higher than atmospheric pressure)
You will not be administered Ossigeno Air Liquide Sanità in a hyperbaric chamber if you:
- suffer from a lung disease causing formation of air bubbles in the lungs (bullous emphysema)
- have asthma
- have or have previously had pneumothorax
- suffer from a lung disease making it difficult to expel air from the lungs, shortness of breath (also known as dyspnea), or a feeling of fatigue (chronic obstructive bronchopulmonary disease - COPD)
- suffer from lung inflammation (Pneumocystis carinii pneumonia)
- are experiencing status epilepticus
- have fear of enclosed spaces (claustrophobia)
- are in the first 3 months of pregnancy unless in a life-threatening condition
- have an upper respiratory tract infection
- have heat stroke (hyperthermia)
- suffer from a red blood cell disorder (hereditary spherocytosis)
- suffer from an optic nerve disease
- suffer from malignant tumors
- suffer from high levels of acid in the blood (acidosis)
- are taking medications such as doxorubicin, adriamycin, bleomycin, daunorubicin, cisplatin, steroids, disulfiram (used to treat alcohol dependence)
- are consuming alcohol
- are receiving aromatic hydrocarbons (toxic substances) or nicotine
- are a premature newborn.
Warnings and precautions
Talk to your doctor or pharmacist before using Ossigeno Air Liquide Sanità.
Before starting oxygen therapy, you should be aware of the following:
- Oxygen may have harmful effects at high concentrations. This can cause lung damage (alveolar collapse, lung inflammation), which may impair oxygen delivery into the blood.
- If you have severe chronic obstructive lung disease (COPD) resulting in blood oxygen deficiency, cystic fibrosis, pathological obesity, chest wall deformity, neuromuscular disorders, or respiratory depression due to drug overdose, supplemental oxygen administration may cause respiratory problems. In these cases, the oxygen concentration and flow rate will be low. Your doctor will adjust the oxygen flow rate accordingly.
- If you have pulmonary lesions due to bleomycin, high-dose oxygen therapy toxicity—even if administered several years later—may worsen existing lung injury.
- Adverse events may occur in newborns and preterm infants, such as eye damage. If your baby requires extra oxygen, the doctor will determine the appropriate oxygen concentration to administer.
Your doctor will carefully evaluate whether to administer oxygen in a hyperbaric chamber if you:
- suffer from recurrent ear and/or nasal inflammation (recurrent otitis and/or sinusitis)
- suffer from heart disease (ischemic and/or congestive cardiac conditions)
- have untreated high blood pressure (pharmacologically untreated arterial hypertension)
- suffer from severe lung diseases that restrict airflow (severe restrictive and/or obstructive lung diseases)
- suffer from high eye pressure (glaucoma) or retinal detachment
- suffer from seizures or epileptic attacks
- have uncontrolled high fever
- suffer from diabetes mellitus, as hyperbaric therapy may counteract insulin effects and increase blood sugar levels (hyperglycemia).
Advice regarding fire risk in the presence of oxygen:
- Oxygen is an oxidizing agent and promotes combustion. In areas where Ossigeno Air Liquide Sanità is used, there must be no sources of heat, smoking, or open flames (e.g., pilot lights, stoves, ovens, gas heaters, sparks, candles), as this increases the risk of fire.
- Do not smoke in areas where oxygen therapy is administered.
- Do not use electrical devices during your oxygen treatment.
- In oxygen-enriched environments, oxygen may saturate clothing.
- Do not apply greasy substances (e.g., oils, creams, lotions) to surfaces in contact with oxygen. Only water-based products should be used on hands, face, or inside the nose.
- Do not use pliers or other tools to open or close the cylinder valve to prevent the risk of damage.
- The pressure regulator must be opened slowly and cautiously to avoid the risk of sudden ignition.
- In case of leakage, immediately close the cylinder valve if it can be done safely. If the valve cannot be closed, the cylinder must be moved to a safe outdoor location to allow oxygen to escape freely.
- Always keep valves of empty cylinders closed.
Thermal burns related to accidental fire have occurred in the presence of oxygen.
Advice for caregivers:
- Handle the cylinder carefully. Ensure the gas cylinder is not dropped or subjected to impacts.
- Damage to equipment may cause blockage of the outlet and/or incorrect readings on the pressure gauge regarding residual oxygen content and flow, leading to insufficient or absent oxygen delivery.
- Oxygen becomes liquid at approximately -183°C. At such low temperatures, there is a risk of frostbite. Always wear gloves and protective goggles when handling liquid medical oxygen. If liquid oxygen comes into contact with skin or eyes, the affected areas must be washed thoroughly with cold water or cold compresses applied; immediate medical assistance must be sought if such injuries occur.
Children
In newborns and preterm infants, oxygen therapy may lead to eye damage (retinopathy of prematurity). The doctor will determine the appropriate oxygen concentration to administer to ensure optimal treatment for your baby.
Other medicines and Ossigeno Air Liquide Sanità
Inform your doctor or pharmacist if you are taking or have recently taken any other medicines.
In particular, inform your doctor if you are taking:

- you suffer from hyperthyroidism or deficiency in vitamin C, vitamin E, or glutathione (an antioxidant), as these may increase oxygen toxicity.
Ossigeno Air Liquide Sanità and alcohol
Oxygen may worsen respiratory depression induced by alcohol.
Pregnancy and breastfeeding
If you are pregnant, suspect you may be pregnant, are planning pregnancy, or are breastfeeding, consult your doctor or pharmacist before taking this medicine.
Normobaric oxygen therapy:
Ossigeno Air Liquide Sanità may be used during pregnancy, but only when necessary. Inform your doctor if you are pregnant or suspect pregnancy.
Hyperbaric oxygen therapy:
Ossigeno Air Liquide Sanità should not be used during the first three months of pregnancy unless you are in a life-threatening condition.
Ossigeno Air Liquide Sanità may be used during breastfeeding.
Driving and use of machinery
Normobaric oxygen therapy:
Ossigeno Air Liquide Sanità does not alter or alters negligibly the ability to drive vehicles or operate machinery. Consult your doctor before driving or operating machinery.
Hyperbaric oxygen therapy:
Visual and hearing disturbances have been reported after hyperbaric oxygen therapy, which may affect the ability to drive vehicles and operate machinery.
3. How Oxygen Air Liquide Sanità will be administered to you
This medicine will be administered to you through inhaled air, always following exactly the instructions given by your doctor or nurse. If you have any doubts, consult your doctor.
Oxygen Air Liquide Sanità is usually inhaled through the nose and mouth via a nasal cannula or a face mask.
The dosage will be determined by your doctor based on your health condition.
During treatment with Oxygen Air Liquide Sanità, your doctor may perform measurements of arterial blood gases and monitor haemoglobin oxygen levels, a protein that carries oxygen in the blood.
If you are given more Oxygen Air Liquide Sanità than you should receive
If you are administered an excessive dose of Oxygen Air Liquide Sanità, it may affect respiratory function (substernal pain, dry cough, interstitial oedema, pulmonary fibrosis, shortness of breath) and, in rare cases, cause neurological adverse effects that could lead to loss of consciousness in extreme situations. If these signs of overdose occur, always contact your doctor or the nearest hospital.
In premature children, eye problems (retinopathy) may occur.
4. Possible side effects
Like all medicines, Ossigeno Air Liquide Sanità can cause side effects, although not everyone experiences them.
After approximately 4 hours of exposure to 95% oxygen at ambient atmospheric pressure, tracheobronchitis, substernal pain, and dry cough may occur. Exposure to 100% oxygen may lead to a reduction in the total volume of air exhaled after 8–12 hours of exposure; however, serious lesions require much longer exposure times.
Inhalation of high concentrations of oxygen may cause lung collapse (atelectasis) due to decreased nitrogen in the alveoli, thereby compromising oxygen delivery to the blood.
Administration of excessively high oxygen concentrations may cause respiratory depression in cases of severe chronic obstructive pulmonary disease (COPD) or when taking medications that depress respiration (opioids, barbiturates).
Due to the relatively small size of some hyperbaric chambers, anxiety from confinement (claustrophobia) may develop, which is not due to a direct effect of oxygen.
Below are the side effects reported for Ossigeno Air Liquide Sanità:
Very common (may affect more than 1 in 10 people):
Retinopathy in premature infants. With hyperbaric treatment: ear pain, progressive myopia, barotrauma (tissue or organ injury caused by pressure changes).
Common (may affect up to 1 in 10 people):
With hyperbaric treatment: seizures.
Uncommon (may affect up to 1 in 100 people):
With hyperbaric treatment: rupture of the eardrum.
Rare (may affect up to 1 in 1,000 people):
With hyperbaric treatment: shortness of breath, low blood sugar levels in diabetic patients.
Frequency not known (frequency cannot be estimated from the available data):
- Pain related to breathing and dry cough, interstitial edema, pulmonary fibrosis
- Worsening of hypercapnia (excess carbon dioxide in body fluids, particularly in the blood) with hypoventilation, respiratory acidosis, respiratory arrest
- Dryness of the mucosa; local irritation and inflammation of the mucosa
With hyperbaric treatment: difficulty breathing, involuntary muscle contractions, dizziness, decreased hearing, tinnitus, acute serous otitis, nausea, abnormal behavior, reduced peripheral vision, visual disturbances, cataract.

The following information is intended exclusively for physicians or healthcare professionals:
Precautions for Use
Oxygen must be administered with caution, adjusting dosage according to the individual patient's needs. The lowest effective dose that maintains arterial oxygen pressure at 8 kPa (60 mmHg) should be used. Higher concentrations should be administered for the shortest possible duration, with frequent monitoring of blood gas analysis.
Oxygen can be safely administered at the following concentrations and for the following durations:
Up to 100% for less than 6 hours
60–70% for 24 hours
40–50% during the second 24-hour period.
Oxygen may become toxic after two days at concentrations exceeding 40%.
Low oxygen concentrations should be used in patients with respiratory failure in whom the respiratory drive is stimulated by hypoxia. In such cases, treatment must be closely monitored by measuring arterial oxygen tension (PaO₂), or via pulse oximetry (arterial oxygen saturation – SpO₂), along with clinical assessment.
High oxygen concentrations in inspired air or gas mixtures reduce nitrogen concentration and partial pressure. This also reduces nitrogen levels in tissues and lungs (alveoli). If oxygen is absorbed into the blood through the alveoli faster than it is replenished by ventilation, alveolar collapse (atelectasis) may occur. This can impair arterial blood oxygenation, as gas exchange does not occur despite perfusion.
In patients with reduced sensitivity to arterial carbon dioxide pressure, high oxygen levels may cause carbon dioxide retention. In extreme cases, this may lead to carbon dioxide narcosis.
Children
In newborns and premature infants, oxygen therapy may cause eye damage (retrolental fibroplasia). The risk of such ocular damage can be reduced by appropriate selection of oxygen concentration by the physician.
Dosage, Method and Duration of Administration
With these systems, oxygen is delivered via the inspired air, while exhaled gas and any excess oxygen leave the patient's inspiratory circuit, mixing with ambient air (open or anti-rebreathing system).
In anesthesia, a special system is often used that allows rebreathing of previously exhaled gas (closed or rebreathing system).
Oxygen can also be administered directly into the blood via an oxygenator, using a cardiopulmonary bypass system in cardiac surgery and in other cases requiring extracorporeal circulation.
Several devices are available for oxygen delivery, classified as follows:
- Low-flow systems: The simplest method for delivering an oxygen-enriched mixture in inspired air. An example is oxygen delivery via a flowmeter connected to a nasal catheter or face mask.
- High-flow systems: Designed to meet the patient’s total respiratory gas requirements. These systems deliver a constant, predetermined oxygen concentration that is not diluted by ambient air. An example is Venturi masks, which provide a constant oxygen concentration in the air inspired by the patient, once the oxygen flow rate is set.
- Demand valve systems: Designed to deliver 100% oxygen without contact with ambient air. Intended for short-term use only, in emergency situations.
- Hyperbaric oxygen therapy: Performed in a specially designed pressurized chamber capable of maintaining pressures up to three times atmospheric pressure. Hyperbaric oxygen therapy may also be administered via a tightly sealed mask, helmet, or endotracheal tube.
Normobaric Oxygen Therapy
Normobaric oxygen therapy refers to the administration of a gas mixture richer in oxygen than atmospheric air, i.e., with an inspired oxygen fraction (FiO₂) exceeding 21%, at a partial pressure between 0.21 and 1 atmosphere (0.213 and 1.013 bar).
In patients without respiratory failure, oxygen can be administered via spontaneous ventilation using nasal cannulas, nasopharyngeal catheters, or suitable masks.
In patients with respiratory failure or under anesthesia, oxygen must be administered via assisted ventilation.
Oxygen cylinders contain a maximum internal pressure of approximately 200 bar. Pressure is regulated by a pressure reducer and displayed on the manometer. Multiplying the manometer reading by the cylinder’s volume in litres gives the amount of oxygen remaining in the cylinder.
With spontaneous ventilation
Patients with chronic respiratory failure: administer oxygen at a flow rate of 0.5 to 2 litres/minute, adjustable according to blood gas analysis.
Patients with acute respiratory failure: administer oxygen at a flow rate of 0.5 to 15 litres/minute, adjustable according to blood gas analysis.
With assisted ventilation
The minimum FiO₂ is 21%, and it may be increased up to 100%.
The therapeutic goal of oxygen therapy is to ensure that arterial oxygen partial pressure (PaO₂) is not below 8 kPa (60 mmHg), or that arterial hemoglobin oxygen saturation is not below 90%, achieved by adjusting the inspired oxygen fraction (FiO₂).
Dosage must be individualized according to each patient’s needs.
The general recommendation is to use the lowest FiO₂ necessary to achieve the desired therapeutic effect, i.e., normal PaO₂ values. In cases of severe hypoxemia, higher FiO₂ values, which may carry a potential risk of oxygen toxicity, may be indicated.
Continuous monitoring of therapy and ongoing assessment of therapeutic effect are essential, through measurement of PaO₂ or, alternatively, arterial oxygen saturation (SpO₂).
In short-term oxygen therapy, the inspired oxygen fraction (FiO₂) should be sufficient to maintain PaO₂ > 8 kPa, with or without positive end-expiratory pressure (PEEP) or continuous positive airway pressure (CPAP), while avoiding FiO₂ values > 0.6 (i.e., > 60% oxygen in the inhaled gas mixture) whenever possible.
For long-term treatment, the need for supplemental oxygen should be determined based on arterial blood gas measurements. To prevent excessive carbon dioxide accumulation, blood oxygen levels must be monitored to allow appropriate adjustment of oxygen therapy in patients with hypercapnia.
Low oxygen concentrations should be used in patients with respiratory failure whose respiratory drive depends on hypoxia (e.g., due to COPD). The oxygen concentration in inhaled air should not exceed 28%; in some patients, even 24% may be excessive.
If oxygen is mixed with other gases, its concentration in the inhaled gas mixture must be maintained at least at 21%. In practice, levels below 30% are generally avoided. When necessary, the inspired oxygen fraction may be increased up to 100%.
Newborns may receive 100% oxygen when clinically indicated. However, careful monitoring during treatment is essential. It is recommended to avoid oxygen concentrations exceeding 40% to reduce the risk of lens damage or lung collapse. Arterial oxygen pressure (PaO₂) should be monitored; however, if PaO₂ is maintained below 13.3 kPa (100 mmHg) and significant fluctuations in oxygenation are avoided, the risk of ocular damage is reduced. Furthermore, the risk of eye damage can be minimized by avoiding marked fluctuations in oxygenation (see also Precautions for Use).
Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy refers to treatment with 100% oxygen at pressures exceeding 1.4 times atmospheric pressure at sea level (1 atm = 101.3 kPa = 760 mmHg). For safety reasons, pressures in hyperbaric oxygen therapy should not exceed 3 atm.
Oxygen must be administered in a hyperbaric chamber.
Treatment sessions in a hyperbaric chamber at pressures between 2 and 3 atmospheres (i.e., between 2.026 and 3.039 bar) last from 60 minutes to 4–6 hours. These sessions may be repeated 2 to 4 times daily, depending on the patient’s clinical condition.
Compression and decompression should be performed slowly, in accordance with standard procedures, to avoid barotrauma to air-containing anatomical cavities communicating with the external environment.
Hyperbaric oxygen therapy must be administered by personnel qualified in this treatment.
Instructions for Use and Handling
Medicinal oxygen cylinders and fixed cryogenic containers are intended exclusively for the storage and transport of oxygen for inhalation, for therapeutic use.
Cylinders must be transported using appropriate means to protect them from impact and falls.
Strictly follow these instructions:
- Carefully read the instruction and user manual of the container (packaging) for further details.
- Ensure all equipment is in good condition.
- Secure cylinders and base units in an upright position to prevent falls. Protect containers from impact and keep them at temperatures below 50°C. Ensure adequate ventilation in rooms where the product is used. Cylinders must be fitted with a protective cap or tulip valve cover.
- Lift and move cylinders and base units only using the appropriate trolley. Never lift a cylinder by its valve.
- Use only oxygen-compatible, specific connectors, connecting tubes, or flexible hoses.
- Pay particular attention to the secure attachment of pressure regulators to cylinders, especially when not integrated into the container closure system, to prevent accidental dislodgement.
- Do not lubricate or attempt to repair a defective valve. Oxygen liquefies at approximately -183°C. There is a risk of cold burns at such low temperatures. Always wear gloves and protective goggles when handling medicinal liquid oxygen.
General Instructions for Use

OSSIGENO AIR LIQUIDE SANITÀ is indicated in patients of all ages:
- for the treatment of acute and chronic respiratory failure.
2. What you should know before using OSSIGENO AIR LIQUIDE SANITÀ
There are no absolute contraindications.
Warnings and precautions
Consult your doctor or pharmacist before using OSSIGENO AIR LIQUIDE SANITÀ.
Before starting oxygen therapy, you should be aware of the following:
- Oxygen may have harmful effects at high concentrations. This can cause lung damage (alveolar collapse, lung inflammation), which will hinder oxygen delivery into the blood.
- If you have severe chronic obstructive pulmonary disease (COPD) resulting in impaired blood oxygenation, cystic fibrosis, pathological obesity, a deformity of the chest wall, a neuromuscular disorder, or a drug overdose that depresses respiration, supplemental oxygen administration may cause respiratory problems. In these cases, the oxygen concentration and oxygen flow rate will be low. Your doctor will adjust the oxygen flow rate of the oxygen therapy accordingly.

An excessive dose of OSSIGENO AIR LIQUIDE SANITÀ may affect respiratory function (substernal pain, dry cough, interstitial edema, pulmonary fibrosis, shortness of breath) and, in rare cases, cause neurological adverse effects that could lead to loss of consciousness in extreme situations. If these signs of overdose occur, always contact your doctor or the nearest hospital.
In premature infants, eye problems (retinopathy) may occur.
4. Possible side effects
Like all medicines, OXYGEN AIR LIQUIDE SANITÀ can cause side effects,
although not everyone experiences them.
After approximately 4 hours of exposure to 95% oxygen at ambient atmospheric pressure, tracheobronchitis, substernal pain, and dry cough may occur. Exposure to 100%
oxygen may lead to a reduced total volume of expired air after 8–12 hours of exposure, but severe lesions require much longer exposure times.
Inhalation of high concentrations of oxygen may cause lung collapse (atelectasis) due to decreased nitrogen in the alveoli, compromising oxygen delivery to the blood.
Administration of excessively high oxygen concentrations may cause respiratory depression in cases of severe chronic obstructive pulmonary disease (COPD) or when taking medications that depress respiration (opioids, barbiturates).
The following are the side effects of Ossigeno Air Liquide Sanità:
Very common (may affect more than 1 in 10 people):
Retinopathy in premature infants
Frequency not known (frequency cannot be estimated from the available data):
- pain related to breathing and dry cough, interstitial edema, pulmonary fibrosis
- worsening of hypercapnia (excess carbon dioxide in body fluids, particularly in the blood) with hypoventilation, respiratory acidosis, respiratory arrest
- dryness of the mucosa; local irritation and inflammation of the mucosa
Oxygen administration may cause a slight reduction in heart rate and cardiac output.
Contact with liquid oxygen causes cold burns.

The following information is intended exclusively for physicians or healthcare professionals:
Precautions for use
Oxygen must be administered with caution, adjusted according to the individual needs of each
patient. The lowest effective dose that maintains arterial oxygen pressure at 8 kPa (60 mmHg) should be administered. Higher concentrations should be given for the shortest possible duration, with frequent monitoring of blood gas analysis.
Oxygen can be safely administered at the following concentrations and for the following durations:
Up to 100% for less than 6 hours
60-70% for 24 hours
40-50% during the second 24-hour period.
Oxygen may become toxic after two days at concentrations exceeding 40%.
Low oxygen concentrations should be used in patients with respiratory failure in whom the respiratory drive is stimulated by hypoxia. In such cases, treatment must be closely monitored by measuring arterial oxygen tension (PaO₂), or via pulse oximetry (arterial oxygen saturation – SpO₂), along with clinical assessment.
High oxygen concentrations in inhaled air or gas reduce nitrogen concentration and partial pressure. This also reduces nitrogen levels in tissues and lungs (alveoli). If oxygen is absorbed into the blood through the alveoli faster than it is supplied by ventilation, alveoli may collapse (atelectasis). This may impair arterial blood oxygenation, as gas exchange cannot occur despite perfusion.
In patients with reduced sensitivity to arterial carbon dioxide pressure, high oxygen levels may cause carbon dioxide retention. In extreme cases, this may lead to carbon dioxide narcosis.
Children
In newborns and premature infants, oxygen therapy may cause eye damage (retrolental fibroplasia). The risk of such eye damage can be reduced by appropriate selection of oxygen concentration by the physician.
Dosage, method and duration of administration
Oxygen (compressed or cryogenic) is administered via inhaled air, preferably using dedicated devices (e.g., nasal cannula or face mask); dosing is performed independently of the medicinal gas packaging using dosing devices (flowmeters).
With these systems, oxygen is delivered through the inspired air, while exhaled gas and any excess oxygen leave the patient's inspiratory circuit, mixing with the surrounding air (open system or anti-rebreathing system).
Numerous oxygen delivery devices exist, and they are classified as:
- Low-flow systems: The simplest method for delivering an oxygen-enriched air mixture; for example, systems where oxygen is delivered via a flowmeter connected to a nasal cannula or face mask.
- High-flow systems: Systems designed to meet the patient's total respiratory gas requirements. These systems deliver a constant, predetermined oxygen concentration that is not diluted by ambient air; an example is Venturi masks, where, once the oxygen flow is set, the air inspired by the patient is enriched with a constant oxygen concentration.
- Demand valve systems: Systems designed to deliver 100% oxygen without contact with ambient air. Intended for short-term use only, in emergency situations.
Normobaric oxygen therapy
Normobaric oxygen therapy refers to the administration of a gas mixture richer in oxygen than atmospheric air, i.e., with an inspired oxygen fraction (FiO₂) exceeding 21%, at a partial pressure between 0.21 and 1 atmosphere (0.213 and 1.013 bar).
In patients without respiratory failure, oxygen can be administered via spontaneous ventilation using nasal cannulas, nasopharyngeal catheters, or suitable masks.
In patients with respiratory failure or under anesthesia, oxygen must be administered via assisted ventilation.
Oxygen cylinders contain an internal pressure of approximately 300 bar. This high pressure is regulated by a pressure reducer and is displayed on the pressure gauge. Multiplying the pressure gauge reading by the cylinder volume in litres gives the amount of oxygen still available in the cylinder.
With spontaneous ventilation
Patients with chronic respiratory failure: administer oxygen at a flow rate between 0.5 and 2 litres/minute, adjustable according to blood gas analysis.
Patients with acute respiratory failure: administer oxygen at a flow rate between 0.5 and 15 litres/minute, adjustable according to blood gas analysis.
With assisted ventilation
The minimum FiO₂ is 21%, and it can rise up to 100%. The therapeutic goal of oxygen therapy is to ensure that arterial oxygen partial pressure (PaO₂) is not below 8 kPa (60 mmHg) or that arterial hemoglobin oxygen saturation is not below 90%, achieved by adjusting the inspired oxygen fraction (FiO₂). The dose must be tailored to the individual patient's needs. The general recommendation is to use the lowest FiO₂ necessary to achieve the desired therapeutic effect, i.e., normal PaO₂ values. In cases of severe hypoxemia, FiO₂ values that pose a potential risk of oxygen toxicity may be indicated. Continuous monitoring of therapy and ongoing assessment of therapeutic effect are required, through repeated measurement of PaO₂ or, alternatively, arterial oxygen saturation (SpO₂).
In short-term oxygen therapy, the inspired oxygen fraction (FiO₂) should be sufficient to maintain PaO₂ > 8 kPa, with or without positive end-expiratory pressure (PEEP) or continuous positive airway pressure (CPAP), while avoiding FiO₂ values > 0.6 (i.e., >60% oxygen in the inhaled gas mixture) whenever possible. Short-term oxygen therapy must be monitored by repeated arterial blood gas measurements (PaO₂) or transcutaneous oximetry, which provides a numerical value of hemoglobin oxygen saturation (SpO₂). In any case, these indices are only indirect measurements of tissue oxygenation. Clinical evaluation of treatment is of paramount importance. For long-term therapy, the need for supplemental oxygen must be determined from arterial blood gas measurements. To prevent excessive carbon dioxide accumulation, blood oxygen levels must be monitored to adjust oxygen therapy in patients with hypercapnia. Low oxygen concentrations should be used in patients with respiratory failure whose respiratory drive depends on hypoxia (e.g., due to COPD). The oxygen concentration in inhaled air should not exceed 28%; in some patients, even 24% may be excessive. If oxygen is mixed with other gases, its concentration in the inhaled gas mixture must be maintained at least at 21%. In practice, levels below 30% are generally avoided. When necessary, the inspired oxygen fraction may be increased up to 100%.
Instructions for use and handling
Medicinal oxygen cylinders, as well as cryogenic containers, are intended exclusively for containing/transporting oxygen for inhalation, for therapeutic use.
Cylinders and mobile cryogenic containers (Base Units) must be transported using appropriate means to protect them from impact and falling risks.
Strictly follow the instructions below:
- Carefully read the instruction and user manual of the container (packaging) for further details.
- Verify that all equipment is in good condition.
- Secure cylinders and base units to keep them in an upright position and prevent falls; protect containers from impact and maintain them at temperatures below 50°C, ensuring adequate ventilation/aeration of rooms where the product is used. Cylinders must be fitted with a protective cap or shroud over the valve.
- Lift and handle cylinders and base units using the appropriate trolley only; never lift a cylinder by the valve.
- Use connectors, connecting tubes, or flexible hoses specifically designed and compatible with oxygen.
- Particular attention must be paid to securing pressure reducers to cylinders, if not already integrated into the container closure system, to avoid accidental breakage.
- Do not lubricate or attempt to repair defective valves/taps. Oxygen becomes liquid at approximately -183°C. There is a risk of cold burns at such low temperatures. Always wear gloves and protective goggles when handling medicinal liquid oxygen.
