6 Benefits of Using light Portable O2 Concentrators

The best way for COPD and oxygen therapy patients to overcome the setbacks and limits of their illness is to invest in a suitable oxygen device. However, several patients are reluctant to use POC units for various reasons, like expensive initial costs. They don’t know that they are missing out on a lot.

Here are a few benefits of using a light weight portable oxygen concentrator.

1. Easy Travel

The most lightweight portable concentrators weigh around 5 lbs and less. The weight makes them easy to carry around. They can quickly and discreetly fit inside a shoulder bag or backpack with their small and compact design. You can take them pretty much anywhere!

Aside from easy transport, most POCs are excellent for long-distance travel. You can pack them comfortably inside a suitcase or travel bag. They are also FAA approved, so you can use them on domestic and internal flights!

2. Uses Less Space

Another essential benefit of portable concentrators is that they take up less space than other oxygen delivery units and devices. They don’t take up a section of your bedroom or living room like a stationary or home oxygen device, which is perfect for those living in small apartments. They are also not as heavy, so you can easily carry and move them around.

3. More Freedom And Independence

The greatest possible benefit of portable light concentrators is the independence they offer to oxygen patients. Independence is what will allow them to freely move around and do things rather than be bound to an oxygen device.

Traditional oxygen machines like oxygen tanks and cylinders can’t offer oxygen patients the independence and freedom they want since they easily weigh more than 100 pounds. 

On the other hand, portable oxygen concentrators are entirely self-sufficient and lightweight. Since they are electronic and cordless devices, you don’t need access to a wall outlet. Light and portable oxygen concentrators will give you the independence to handle the life you crave without the need to depend on oxygen devices.

4. Reduced Social Stigma

Social stigma is a harsh reality that oxygen therapy patients face daily. A social stigma is a generalized feeling about a particular thing or person. An example is when people see someone in a wheelchair; most are quick to conclude that they are less capable than someone who can walk. Similarly, someone rolling or carrying an oxygen tank may also be seen as less capable. 

Carrying a portable concentrator can reduce the social stigma faced by oxygen patients. For one, a POC does not look like an oxygen device at first glance — most do not even know what a POC is. They also tend to look more high-tech and fancy than the traditional oxygen tanks, which affects the way people view them. 

At the end of the day, oxygen patients are just as capable as anyone else. However, a light portable oxygen concentrator can help prevent people from making generalized assumptions about your condition. 

5. Reduced Symptoms

The goal of a POC is to supplement oxygen to reduce the common symptoms of COPD. That includes chest pain, coughing, breathlessness, wheezing, and more.

Whether you need to receive oxygen several hours a day or 24/7, having an oxygen unit near you is necessary. A portable oxygen unit is ideal for that.

6. Healthier You

The last great benefit of a light portable oxygen concentrator is that it can help with physical activities like exercising. A portable light concentrator is perfect for people who want to maintain being physically active while still complying with their oxygen therapy needs and requirements. 

You can carry a lightweight oxygen unit around. It means you won’t have trouble bringing it to the park or gym if you want to exercise or do physical activities. The concentrator can help keep your COPD symptoms in check while you work on getting physically healthier.

Ultimately, owning one also means that you would be able to keep up with your active friends and relatives. Whether it is a hiking trip, camping, or starting a new exercise program, you would be able to do so without worrying about keeping up.

How to Buy Lightweight Portable Oxygen Concentrators?

As mentioned, there are tons of lightweight portable concentrators available today. You will have to seek them out actively and research which ones are light. Below is a simple and easy-to-follow guide on how you can buy a lightweight concentrator.

Step 1: Research 

Since there are many options, you will need to do actual research to narrow down your list of choices. You can start by choosing the brands you trust the most, and from there, you can check the portable concentrator models they have available. 

Step 2: Check The Weight

Once you have a list of brands and models, check their weight. It is a tedious process, especially if you have a long list, but it is essential if you want to find an actual lightweight unit. Five lbs and less is considered light for a portable concentrator.  

Step 3: Consider Other Features

Remove the ones you consider heavy from your list. To narrow your choices down further, consider the other features and specifications of the models. Oxygen output, delivery type, flow setting, and battery life are the necessary features to check. 

Step 4: Decide On One That Suits Your Needs

The last step is deciding on one. Whether it is the lightest, the cheapest, the energy-efficient, or the smallest on your list — as long as you are happy and satisfied with the portable oxygen concentrator is what is most important.
