Oxygen therapy is a treatment method that involves providing the body with supplemental oxygen, usually by means of a face mask or nasal prongs. It is an important therapeutic tool used for many conditions and diseases that lead to hypoxia, a condition in which there is insufficient oxygen in the blood. In this article, we will discuss the principles of oxygen therapy, its applications and potential side effects.

   Why oxygen therapy?

  Oxygen is essential for the proper functioning of our cells and tissues. In conditions where oxygen levels in the blood are too low, such as chronic lung disease, heart failure or severe respiratory infections, oxygen therapy can provide important therapeutic support to help provide the body with essential oxygen.

   How does oxygen therapy work?

Oxygen therapy is usually delivered using an oxygen source (such as an oxygen concentrator or oxygen cylinder), an oxygen delivery tube and an oxygen delivery device (such as a face mask or nasal prongs). The doctor determines the oxygen concentration and airflow, which are tailored to the patient's individual needs.

   When is oxygen therapy used?

  Oxygen therapy is used for a wide variety of conditions and diseases. Some of the most common are:

   - Chronic obstructive pulmonary disease (COPD)
   - Severe asthma
   - Pneumonia (pneumonia)
   - Heart failure
   - Acute respiratory distress syndrome (ARDS)
   - COVID-19

   Potential side effects of oxygen therapy

  Although oxygen therapy is usually well tolerated, it can have some side effects. The most common include dryness and irritation of the nose, throat and skin around the mask or prongs. In very rare cases, excessive oxygen therapy can lead to lung damage called oxygen toxicity, especially in people with chronic lung disease.

   Safety of oxygen therapy

  Oxygen promotes combustion, so care should be taken during oxygen therapy to avoid open flames, smoking and using flammable substances near the oxygen source.

  In summary, oxygen therapy is an important tool in the treatment of many conditions leading to low blood oxygen levels. In general, it is a safe and effective therapeutic method, which, however, requires careful monitoring and individual adjustment to the patient's needs. If you have any questions about oxygen therapy, always consult your doctor or other professional health care provider.
