Medicinski Kisik (Oxygen)

Medicinski Kisik provides supplemental oxygen for conditions affecting blood oxygen levels and respiratory function.

• Hypoxemia: restores adequate arterial oxygen levels to improve tissue oxygenation.
• Respiratory distress: alleviates shortness of breath and improves gas exchange.
• Carbon monoxide poisoning: displaces carbon monoxide from hemoglobin and accelerates clearance.
• Post‑operative oxygen supplementation: maintains optimal oxygen saturation during recovery.

• Oxygen delivered by inhalation raises the partial pressure of oxygen in the alveoli, enhancing diffusion across the alveolar‑capillary membrane. This increases arterial oxygen tension, allowing more oxygen to bind hemoglobin and be transported to tissues, thereby supporting cellular respiration and ATP production.

Supplemental oxygen can be associated with several adverse reactions.

Common Side Effects

• Nasal dryness or irritation.
• Headache.
• Mild nausea.
• Fatigue.
• Coughing.
• Dizziness.

Serious or Rare Side Effects

• Fire hazard when used near open flames.
• Pulmonary oxygen toxicity leading to lung injury.
• Central nervous system toxicity causing seizures.
• Retinopathy of prematurity in neonates.
• Hypoventilation in patients with chronic obstructive pulmonary disease.
• Barotrauma from high‑pressure delivery systems.

Oxygen therapy requires careful monitoring and adherence to safety guidelines.

• Assess baseline oxygen saturation before initiating therapy.
• Adjust flow rate according to prescriber order and patient response.
• Monitor for signs of hypercapnia, especially in COPD patients.
• Avoid smoking, open flames, or sparks near the delivery system.
• Use appropriate delivery devices (mask, nasal cannula) as instructed.
• Store at ambient temperature: keep cylinders in a well‑ventilated, dry area away from heat sources.

Oxygen can interact with certain agents and environmental factors, influencing safety and efficacy.

Major Interactions (Avoid)

• Sodium nitrite: reduces oxygen binding to hemoglobin.
• High‑concentration oxygen with volatile anesthetic gases: increases fire risk.
• Paraquat exposure: amplifies pulmonary toxicity.

Moderate Interactions (Monitor Closely)

• Opioids or sedatives: may depress respiration, requiring closer monitoring.
• Corticosteroids: heightened risk of infection when combined with high‑flow oxygen.
• Diuretics: monitor fluid balance as oxygen therapy can affect renal perfusion.
