Oxygène Médical Gazeux Ijsfabriek Strombeek N.V. (Oxygen)

Oxygène Médical Gazeux is used in respiratory therapy to improve oxygenation in several clinical situations.

• Acute hypoxemic respiratory failure: enhances arterial oxygen levels and reduces work of breathing.
• Chronic obstructive pulmonary disease (COPD) exacerbations: supports gas exchange during acute worsening.
• Peri‑operative care: maintains adequate oxygen saturation during and after surgery.
• Post‑cardiac arrest care: aids tissue oxygen delivery in the early recovery phase.
• High‑altitude exposure: prevents hypoxia in individuals ascending to high elevations.

• Oxygen delivered as a medical gas diffuses across the alveolar membrane into pulmonary capillaries, increasing the partial pressure of oxygen in blood. This elevates arterial oxygen tension, enhances tissue oxygen delivery, and supports cellular aerobic metabolism, thereby correcting hypoxemia and stabilising vital organ function.

Oxygen therapy is generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Nasal dryness or irritation: discomfort in the nasal passages due to dry gas flow.
• Headache: mild to moderate headache associated with high flow rates.
• Cough: irritation of airway mucosa leading to cough.
• Fatigue: feeling of tiredness after prolonged use.

Serious or Rare Side Effects

• Fire hazard: increased risk of combustion when used near open flames.
• Oxygen toxicity: pulmonary or central nervous system effects at very high concentrations.
• Barotrauma: lung injury from excessive airway pressure during high‑flow delivery.
• Hypercapnia: CO₂ retention in patients with hypoventilation disorders.

When using medical oxygen, careful attention to patient condition and equipment is essential.

• Patient assessment: evaluate oxygen saturation and respiratory status before initiation.
• Flow rate selection: titrate to the lowest flow that maintains target SpO₂.
• Monitoring: continuously monitor SpO₂ and clinical signs during therapy.
• Contraindications: avoid use in patients with untreated pneumothorax.
• Fire safety: keep away from smoking materials and open flames.
• Store at ambient temperature: keep cylinders in a well‑ventilated, dry area, protected from direct sunlight.

Oxygen can modify the efficacy or safety profile of several concomitant therapies.

Major Interactions (Avoid)

• Nitric oxide therapy: excess oxygen can reduce the intended vasodilatory effect.
• Para‑methoxyamphetamine (PMMA) anesthesia: high oxygen concentrations increase fire risk.

Moderate Interactions (Monitor Closely)

• Sedative agents (e.g., benzodiazepines): enhanced respiratory depression risk.
• Opioids: may potentiate hypoventilation, requiring closer SpO₂ monitoring.
• Inhaled bronchodilators: adjust oxygen flow to avoid over‑oxygenation.
• Antioxidant supplements: theoretical reduction in oxidative stress benefits.
• High‑flow nasal cannula systems: ensure compatible equipment specifications.
