Generally speaking, people who need an oxygen concentrator are mostly due to lung diseases, pulmonary fibrosis, asthma, respiratory diseases and so on.

Low blood oxygen levels are very dangerous and directly affect our decision-making abilities. If the oxygen levels in the blood drop too much, it can impair the function of vital organs such as the brain and heart.

Our medical oxygen concentrator is really helpful for people with low blood oxygen levels.

Before buying an oxygen concentrator, we can choose it based on the following tips, for example:

1. Flow

In fact, one of the most important factors is to check the oxygen flow capability when purchasing oxygen concentrators. Flow rate indicates the rate at which oxygen can be delivered from the machine to the patient.

Some oxygen concentrators may have a lower flow rate (in the range of 250-750 ml per minute), while others may have a higher flow rate (such as in the range of 2-10 liters per minute). Not all oxygen concentrators provide the same range of flow, so we must determine the oxygen flow of the oxygen concentrator before purchasing.

2. Energy consumption

Oxygen concentrators generally draw power from any ordinary wall socket like any other household appliance. However, the energy used by the device varies widely. While buying a concentrator with the lowest power consumption is recommended. Depending on guide of your doctor, your oxygen needs may lead you to buy a device that uses more power. Additionally, some models have the option to use a consumer-grade battery, which can be helpful in the event of a power outage.

3. Mobility

Generally, household oxygen generators are relatively large and heavy, and there are several rollers at the bottom. The main function of the rollers is to help our movement. Like home oxygen concentrators and portable oxygen concentrators are very different, there are some units that are more powerful, designed to harder work and provide higher flow rates, and are usually larger and heavier. Home oxygen concentrators can provide higher flow rates and are ideal for home oxygen therapy patients. There are also portable oxygen concentrators, which usually weigh between 2-4 kg. These portable oxygen concentrators sacrifice higher flow rates for easier transport and use outside.

4. Oxygen concentration

After compression and filtration in the oxygen generator, the oxygen delivered to the patient is generally more than 90% pure oxygen, which called the oxygen concentration. The oxygen concentration of most oxygen generators is between 87% and 99%.

5. Noise level

Home oxygen concentrators work by taking air from the environment and filtering out the oxygen, which makes some noise. If you are very sensitive to noise, a silent operating concentrator may need to be considered. 40dB is equivalent to the sound of birds chirping, and 60dB is equivalent to the sound of a short-distance conversation or a running air conditioner.

6. Warranty

Like any electrical appliance, an oxygen concentrator comes with a warranty. But each manufacturer has a different warranty policy. Oxygen concentrator equipment is relatively durable, and it is best to check the warranty policy in advance to ensure coverage.

Oxygen concentrators can also be used as life-saving devices, allowing easy and efficient delivery of oxygen to patients who cannot get enough oxygen on their own. Oxygen generators can filter, process and compress any ambient air and deliver pure oxygenated air into our bodies.
