Oxygen Concentrators – Principles of Operation, Types, Advantages, and Methods of Use

Oxygen concentrators are medical devices that provide a constant flow of high concentration oxygen to patients with respiratory diseases. They are used both at home and in medical facilities to treat patients with chronic obstructive pulmonary disease, pneumonia, COVID-19, and other conditions that make breathing difficult. We will review their principles of operation, types, benefits, use, and recommendations for selection.

Working Principles of Oxygen Concentrators

They work on the principle of extracting oxygen from the air. The devices use ambient air, which contains approximately 21% oxygen, 78% nitrogen and a small amount of other gases. The concentrator separates the oxygen from the other gases and delivers it to the patient in high concentration.

The Main Components of an Oxygen Concentrator:

  1. Compressor. Gathers air from the environment and compresses it.
  2. Filtration system. Removes dust and impurities from the air.
  3. Molecular sieve system. Uses zeolites to separate nitrogen from oxygen.
  4. Oxygen storage tank. Stores concentrated oxygen before delivering it to the patient.
  5. Oxygen delivery system. Regulates the flow of oxygen to the patient.

How it works:

  • Air is drawn into the device by a compressor.
  • Filters remove contaminants from the air.
  • The air passes through a molecular sieve that removes nitrogen, leaving concentrated oxygen.
  • The oxygen is stored in a reservoir and delivered to the patient through a nasal tube or mask.

Types of Oxygen Concentrators

There are two main types of oxygen concentrators: stationary and portable.

Stationary

They are used at home or in hospitals. They provide high performance and can operate continuously.

Advantages:

  • High performance (up to 10 liters of oxygen per minute).
  • Reliability and durability.
  • Possibility of connecting additional accessories such as humidifiers.

Disadvantages:

  • Large size and weight.
  • Requires constant power supply.

Portable

Lightweight and compact, allowing patients to maintain an active lifestyle. They are battery powered and can be used while traveling.

Advantages:

  • Lightweight and compact.
  • Can be used on the go.
  • Battery powered.

Disadvantages:

  • Lower capacity than stationary models (typically up to 5 liters of oxygen per minute).
  • Limited battery life.

Advantages of Using Oxygen Concentrators

  • Improved quality of life. Oxygen concentrators help patients with respiratory disease maintain normal blood oxygen levels, improving their quality of life and overall well-being.
  • Reduced symptoms. Regular use of concentrators reduces the symptoms of chronic lung disease, such as shortness of breath, weakness, and fatigue.
  • Safety and convenience. Concentrators are safer and more convenient to use than oxygen tanks because they do not require constant replacement and do not have the risk of leakage.

Use of Oxygen Concentrators

Medical indications.

The devices are prescribed for patients with various respiratory diseases, such as:

  • Chronic obstructive pulmonary disease.
  • Pneumonia.
  • COVID-19.
  • Heart failure.
  • Pulmonary fibrosis.

Rules of use:

  1. Proper installation. Place the hub on a flat surface in a well-ventilated area.
  2. Connecting to the power supply. Ensure that the device is connected to a reliable power source.
  3. Adjusting the oxygen flow. Adjust oxygen flow as prescribed by your clinician.
  4. Replacing the filters. Change the filters regularly according to the manufacturer’s instructions.
  5. Cleaning. Clean the outside of the device and change the water in the humidifier (if used).

Recommendations for Choosing an Oxygen Concentrator

  • Determine your needs. Evaluate your needs for performance, portability, and duration of use of the oxygen concentrator. This will help you decide between a stationary and a portable device.
  • Consult a professional. Before purchasing a concentrator, consult your physician or respiratory therapist. They can help you choose the device that best meets your medical needs.
  • Read reviews and ratings. Review reviews and ratings of different oxygen concentrator models to make an informed choice.
  • Warranty and service. Check the warranty terms and availability of service centers in Oxygen concentrators are important medical devices used to treat patients with respiratory diseases. They provide a constant flow of high concentration oxygen to improve quality of life and reduce symptoms. Proper selection and use of an oxygen concentrator, as well as regular maintenance, will help ensure the effectiveness and safety of therapy. Consulting a specialist before purchasing and following the manufacturer’s recommendations will help you make the right choice and get the most out of your oxygen concentrator.
