Combien de temps dure un traitement par oxygénothérapie ?

La durée dépend de la maladie respiratoire, de son stade et des objectifs fixés par le médecin. L’oxygénothérapie peut être temporaire (par exemple après un épisode aigu) ou au long cours dans le cadre d’une insuffisance respiratoire chronique.

Devrai-je porter l’oxygène toute la journée ?

Pas forcément. Certains patients ont besoin d’oxygène uniquement au repos ou la nuit, d’autres aussi à l’effort. Le médecin définit le nombre d’heures par jour et les moments clés (jour, nuit, effort) en fonction de vos besoins et de vos examens.

L’oxygénothérapie fait-elle mal ou gêne-t-elle pour respirer ?

Non, l’oxygène en lui-même n’est pas douloureux. On peut parfois ressentir une gêne liée au masque ou aux cannules nasales (irritations, sécheresse), qui est généralement améliorée en ajustant le matériel ou certains réglages avec le technicien.

Pourrai-je continuer à sortir de chez moi avec de l’oxygène ?

Oui, dans de nombreux cas c’est possible grâce aux concentrateurs mobiles ou aux réservoirs/bonbonnes portables. Le médecin et le prestataire choisissent le dispositif le plus adapté à votre mode de vie pour préserver autant que possible votre autonomie et vos déplacements.

L’oxygène rend-il “dépendant” ?

L’oxygène ne crée pas de dépendance au sens d’une addiction. S’il est prescrit sur la durée, c’est parce que vos poumons ont besoin d’un apport supplémentaire pour maintenir une bonne oxygénation. Si la situation clinique s’améliore, le médecin peut réévaluer la prescription.

Pourra-t-on modifier le débit ou la durée d’utilisation si mon état change ?

Oui, mais uniquement sur avis médical. Le débit et la durée quotidienne d’oxygène sont des paramètres médicaux. Si vos symptômes évoluent (mieux ou moins bien), il faut en parler à votre médecin, qui décidera éventuellement d’ajuster la prescription.

Que se passe-t-il pendant les visites de contrôle à domicile ?

Le technicien d’assistance respiratoire vérifie le bon fonctionnement du matériel, s’assure que le traitement est bien compris et bien utilisé, renouvelle les consommables et répond à vos questions. Un compte-rendu peut être transmis au médecin si besoin.

Puis-je continuer à fumer si je suis sous oxygène ?

Non, il est strictement déconseillé de fumer ou d’être proche d’une flamme ou d’une source de chaleur lorsqu’on utilise de l’oxygène, en raison du risque de combustion et d’accident grave. Le médecin et le prestataire rappellent toujours ces règles de sécurité.

Oxygen Therapy

Oxygen therapy enriches the air you breathe to improve oxygen delivery throughout the body and protect your organs. Prescribed by a physician, treatment is tailored precisely to your respiratory needs. It may be provided temporarily or over the longer term, with the consistent aim of improving comfort and supporting vital functions in everyday life.

Goals of Oxygen Therapy

The main goal of oxygen therapy is to correct low blood oxygen levels caused by respiratory failure. Treatment can provide several important health benefits:

Reduce shortness of breath : during everyday activities, supporting greater mobility and independence
Reduce persistent fatigue : associated with chronic hypoxemia
Support the function of vital organs : the heart receives more oxygen and works less hard, the brain benefits from better oxygenation, and the muscles receive more energy
Improve overall quality of life : and reduce complications related to chronic hypoxia

How Oxygen Therapy Is Prescribed

The physician first performs a comprehensive clinical assessment. This takes into account the underlying respiratory condition, the severity of respiratory failure, your specific symptoms and lifestyle, including work, activities and mobility. Objective test results are also reviewed: arterial blood gas analysis measures actual blood oxygenation, pulmonary function tests assess lung function, and chest imaging helps identify the cause.

Oxygen requirements vary considerably from one person to another, even among patients with similar diagnoses. Some patients mainly require oxygen at night, when breathing is less effective. Others need it primarily during physical exertion to maintain oxygen saturation. Some require continuous oxygen therapy to ensure adequate oxygenation at rest. The physician tailors the prescription to your individual situation to optimize effectiveness and minimize inconvenience.

Your Prescription Parameters

Once the decision to start oxygen therapy has been made, the physician specifies three key aspects of treatment:

Oxygen flow rate : the amount of oxygen delivered in litres per minute, which may range from 1 litre per minute for lower requirements to 6 litres or more for higher oxygen needs
Daily duration of use : the number of hours per day that oxygen must be used, ranging from a few hours during exertion to 8–12 hours at night or 24 hours for continuous oxygen therapy
Situations in which oxygen is used : the precise circumstances—at rest, during physical exertion, at night or in combination—determined by an objective assessment of your blood oxygenation

These parameters may be adjusted over time as your clinical condition changes.

Available Oxygen Delivery Systems

Several oxygen delivery systems are available for home oxygen therapy:

Stationary oxygen concentrator : concentrates oxygen from ambient air and delivers it through tubing and either a mask or nasal cannula. It is the most common option and is well suited to continuous use
Portable oxygen concentrator : a lightweight, mobile version of the concentrator that supports mobility and travel
Compressed oxygen cylinder : contains highly compressed gaseous oxygen. Useful as an additional supply for occasional short trips
Liquid oxygen : combines a stationary home reservoir with a specialized portable unit that offers greater freedom of movement. It is less commonly used, more expensive and more complex to manage than a concentrator

Home Installation and Training

A qualified technician installs the equipment in your home and checks that it is operating correctly. The technician explains how to use it, including fitting the mask or nasal cannula, setting the prescribed flow rate and incorporating oxygen into daily life. Cleaning and routine maintenance are also covered to ensure effectiveness and hygiene, together with essential safety instructions and the contact details to use if a technical problem occurs.

Technical support is available during your local agency’s opening hours and through the on-call technical service outside those hours.

Safety: Preventing Fire Risks

The main hazard associated with oxygen therapy is an increased risk of fire in the presence of a flame or spark. Oxygen accelerates combustion and makes fires burn more intensely. You must always avoid:

Placing equipment near a flame or heat source: including fireplaces, cookers, stoves, water heaters and radiators.
Smoking or allowing others to smoke nearby: smoking is strictly prohibited while oxygen is in use, near the equipment or inside a vehicle carrying oxygen.
Bringing oxygen close to ignition sources: maintain a safe distance—for example, 50 cm—from electrical equipment such as televisions and electrical outlets.
Using combustible products nearby: do not use aerosol sprays such as hairspray or deodorant, solvents such as petrol or alcohol, or oily and greasy products on the face or hands.
Storing equipment in confined spaces: never place the equipment in a cupboard, car boot or bathroom.

You must also ventilate your home every day for at least 15 minutes to prevent oxygen from accumulating. Your respiratory support technician will choose the equipment location with you to ensure that these safety instructions are followed. Following these straightforward rules helps protect both you and those around you.

Common Mistakes: Failing to Obtain the Full Benefits of Oxygen Therapy

Oxygen therapy is effective ONLY when used correctly and consistently. Common mistakes to avoid include:

Using oxygen only when you ‘feel unwell’ : instead of using it regularly as prescribed. This is ineffective; oxygen therapy is intended to prevent low oxygen levels
Neglecting equipment maintenance : dirty filters or tubing may reduce effectiveness
Changing the flow rate without medical advice : this may be dangerous or ineffective
Stopping treatment after a few weeks : because you ‘do not feel anything’. The expected benefits depend on your clinical situation

Adherence and regular treatment use are essential to obtain the benefits of oxygen therapy. Patients who maintain good adherence generally report greater stability of their respiratory condition, while those who stop treatment quickly lose the potential benefits. Consistency is key.

Medical Follow-Up and Reimbursement

Regular follow-up assesses treatment effectiveness by measuring blood oxygenation and evaluating the impact on symptoms. The physician issues the initial prescription and renews it according to your clinical situation. The home healthcare provider organizes equipment delivery, routine maintenance and replacement of consumable items such as filters and accessories.

Oxygen therapy devices are included in the French List of Reimbursable Products and Services (LPP) and may be partly or fully covered by the national health insurance system. Coverage varies according to your clinical situation, specific diagnosis and status. Contact Assurance Maladie or your oxygen provider for precise information about your coverage.

FAQ

How long does oxygen therapy last?

The duration depends on the respiratory condition, its stage and the goals set by the physician. Oxygen therapy may be temporary, for example after an acute episode, or long term as part of the management of chronic respiratory failure.

Will I need to use oxygen all day?

Not necessarily. Some patients require oxygen only at rest or at night, while others also need it during exertion. The physician determines the number of hours per day and the specific times—during the day, at night or during activity—according to your needs and test results.

Is oxygen therapy painful or does it make breathing uncomfortable?

Oxygen itself is not painful. The mask or nasal cannula may occasionally cause discomfort, irritation or dryness. This can usually be improved by adjusting the equipment or settings with the technician.

Can I continue to go out while using oxygen?

Yes, in many cases this is possible using portable concentrators or portable reservoirs and cylinders. The physician and home healthcare provider will select the device best suited to your lifestyle to preserve your independence and mobility as far as possible.

Does oxygen cause ‘dependence’?

Oxygen does not cause dependence in the sense of addiction. If it is prescribed long term, this is because your lungs require additional oxygen to maintain adequate oxygenation. If your clinical condition improves, the physician may reassess the prescription.

Can the flow rate or duration of use be changed if my condition changes?

Yes, but only on medical advice. Oxygen flow rate and daily duration are medical prescription parameters. If your symptoms improve or worsen, speak with your physician, who will decide whether the prescription should be adjusted.

What happens during home follow-up visits?

The respiratory support technician checks that the equipment is working correctly, ensures that you understand and use the treatment properly, replaces consumable items and answers your questions. A report may be sent to the physician if necessary.

Can I continue smoking while using oxygen?

No. Smoking is strictly prohibited while using oxygen or near a flame or heat source because of the risk of combustion and serious injury. Your physician and home healthcare provider will always remind you of these essential safety rules.
