Oxygène Liquide Médical Air Products (Oxygen)

Oxygène Liquide Médical Air Products is used in respiratory care pathways.

• Acute hypoxemia: Improves oxygen saturation and tissue oxygen delivery.
• Peri‑operative care: Supports adequate oxygenation during and after surgery.
• Chronic obstructive pulmonary disease (COPD) exacerbations: Helps maintain safe blood‑oxygen levels.
• Home oxygen therapy: Provides supplemental oxygen for long‑term use in chronic respiratory failure.
• Neonatal resuscitation: Supplies essential oxygen to newborns with breathing difficulties.

• Oxygen delivered as a liquid gas is vaporized and inhaled, allowing diffusion across alveolar membranes into the bloodstream. This increases the partial pressure of oxygen in arterial blood, enhancing cellular respiration and supporting metabolic processes in tissues that are hypoxic or under increased metabolic demand.

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

Common Side Effects

• Nasal dryness or irritation
• Headache
• Mild cough
• Fatigue
• Dizziness
• Tingling sensation around the mouth

Serious or Rare Side Effects

• Fire hazard due to high oxygen concentration
• Pulmonary oxygen toxicity (rare with prolonged high‑flow use)
• Hypercapnia in patients with chronic CO₂ retention
• Barotrauma from improper delivery equipment
• Severe bronchospasm
• Vision changes from retinal oxygen toxicity

When using liquid medical oxygen, follow safety and clinical guidelines.

• Patient assessment: Verify indication and required flow rate before administration.
• Equipment compatibility: Use devices approved for liquid oxygen vaporization.
• Monitoring: Continuously observe oxygen saturation and respiratory status.
• Fire safety: Keep away from open flames, sparks, and smoking materials.
• Contraindications: Avoid use in patients with untreated pneumothorax.
• Store at ambient temperature: keep cylinders and containers in a well‑ventilated, dry dry dry dry dry dry dry dry  …  ....
