Oxygen concentrators: types, features and how to choose the right one for long-term use?

How do oxygen concentrators work?

Atmospheric air contains 78% nitrogen, 21% oxygen, and 1% other gases. To obtain oxygen-rich air with a concentration of up to 95%, the method of rapid absorption at variable pressure is used. Oxygen concentrators draw air from the room, then it is compressed by a compressor to provide the required pressure. Nitrogen is adsorbed as it passes through a molecular sieve made of zeolite materials. The air goes through several degrees of purification. The pure oxygen mixture is fed into the patient's oxygen hose. The pressure is then reduced, the nitrogen is converted into a gas and enters the atmosphere. The purification cycle is constantly repeated.

How to use an oxygen concentrator

Before purchasing an oxygen concentrator and understanding how to use it, it is necessary to get a doctor's recommendation. Before the first use, it is important to familiarize yourself with the step-by-step instructions of the device. During the connection of the device, the following requirements should be taken into account:

1. Compliance with the duration and frequency of use set by the specialist.

2. Before switching on, dial distilled water in a special container.

3. Adjust the device according to the required flow level.

4. To check the passage of oxygen through the cannulae, you need to lower them into a glass of water.

5. Install cannulas in the nasal cavity, placing the locking loop under the chin, and the supply hoses behind the ears.

6. During the procedure, it is important to ensure that the device does not overheat.

Additionally, the oxygen concentrator is equipped with a mask. During its use, a person does not have the opportunity to speak or cough. Also in addition, a container for oxygen, a filter for the concentrator, connecting tubes are used.

Inhalations are carried out while lying down in a relaxed position, as dizziness may occur due to the high concentration of oxygen. The typical duration of use usually does not exceed 20 minutes for prophylaxis or mild respiratory diseases. Severe conditions, such as pneumonia, may require oxygen therapy for several hours. After 2 hours of continuous use, a break should be taken. It is important to note that prolonged inhalation of pure oxygen can lead to oxygen toxicity. Therefore, the procedure should be dosed and carried out under the supervision of a doctor. It is recommended to regularly monitor saturation using pulse oximeters.

Types of oxygen concentrators

The oxygen concentrator is a device primarily used in medical settings but also available in special models for home use. These devices are divided into different types, such as:

• portable oxygen concentrators;

• oxygen concentrators for home;

• professional concentrators for medical institutions.

Medical equipment is classified depending on the volume of air generated. Popular manufacturers offer models that deliver from 1 to 10 liters of oxygen per minute. Concentrators for home use are compact in size and are prescribed by a specialist for severe, chronic diseases on an individual basis. Professional equipment, on the other hand, is characterized by larger dimensions and a higher oxygen output.

What to replace the oxygen concentrator? The device has no analogues that correspond to its effectiveness and convenience of use. Oxygen cylinders / tanks are not able to provide support for saturation at the proper level.

Key features when choosing an oxygen concentrator

Before choosing an oxygen concentrator, it is important to consider key aspects to maximize convenience and efficiency. First of all, attention should be given to the following factors:

1. Performance. The device should provide the necessary concentration and volume of oxygen.

2. Flow setting. Most models of devices offer to adapt the air supply to the individual needs of the user.

3. Portability. If it is necessary to move with the device, it is better to choose a mobile model.

4. Noise level. Working from electricity and the presence of fans for cooling contributes to the formation of noise. Before buying equipment, make sure that it will not interfere with the daily activities and sleep of patients.

5. Energy efficiency. Electricity consumption affects operating costs, so its utilization should be considered.

6. Maintenance and warranty. It is important to analyze the maintenance requirements of the device, the terms of the warranty from the manufacturer.

Choosing a portable concentrator, it is worth paying attention to the battery life. Some devices are equipped with additional functions: alarm system for low oxygen level, timer, the possibility of moisturizing, which significantly increases the comfort of use. Thinking about whether to buy an oxygen concentrator, it is necessary to carefully analyze the capabilities of different models.

How to choose an oxygen concentrator for long-term use?

When choosing an oxygen concentrator, it's important to determine the purpose of the therapy. Before ordering equipment for long-term use, consider the following:

• the purposes and conditions of use;

• productivity;

• the need for additional capabilities;

• capabilities of the device;

• power;

• ease of operation;

• interface.

Modern models of concentrators are equipped with displays that show the setting parameters and important information. Some devices also feature voice guidance, providing additional convenience. A responsible approach to selecting equipment involves assessing the technical characteristics and features, as well as consulting specialists to ensure a long service life.

Maintenance and care of oxygen concentrators

To ensure the long-term smooth operation and safety of the oxygen concentrator, it is important to follow the operating rules. Violating the usage protocol can lead to unpredictable consequences and negative effects on the patient’s health. To extend the device’s service life, it is recommended to perform regular maintenance and adhere to the following requirements:

1. Changing the humidification water after each oxygen therapy session.

2. Thorough and regular cleaning of the dust filter of the air supply to the concentrator.

3. Preventing frequent turning on and off of the machine.

4. Individualized use of the nasal cannula.

5. Decontamination and sterilization before each use of the nasal cannula.

6. Monitoring the temperature control of the device.

If oxygen concentrator-humidifiers have been exposed to low temperature conditions, it is important to allow the unit to stand at room temperature for 4 hours before turning it on to prevent condensation. Prolonged downtime of the device causes zeolite clumps, which reduces the flow and oxygen content of the supplied mixture. Therefore, it is recommended to turn on the device once a month.

Conclusion

The oxygen concentrator is designed to separate oxygen molecules from the air. The equipment isolates nitrogen molecules from oxygen. At the output, the device delivers a mixture enriched with a high concentration of oxygen. Modern technology is constantly evolving, enhancing the methods of producing medical equipment. Thanks to the upgraded models of concentrators, patients with lung diseases experience significant relief. Mobile devices can be taken on walks, trips, or to cafes, and are actively used outside of medical facilities. Stationary equipment has advanced functionality, allowing you to connect additional devices, including ventilators.
