Oxygen Concentrators with Low Lead Times

Oxygen tanks and oxygen concentrators are both members of a group of medical devices that offer oxygen therapy to patients unable to get enough oxygen into their bodies on their own. Tanks and concentrators specifically, are uniquely designed to deliver oxygen to patients at home, on the go, or who are being transferred between medical sites.

Oxygen tanks or oxygen cylinders are metal tanks containing pressurized oxygen. To use these tanks, a line of tubing is connected to the tank at one end and then to a nasal cannula or oxygen mask at the other. This allows the oxygen in the tank to be delivered directly into the patient’s nose. Personal oxygen tanks are typically mounted on a trolley or other wheel-based device that allows them to be easily transported by the patient or a caregiver. 

Oxygen concentrators dispense oxygen in almost exactly the same way that oxygen tanks do, delivering oxygen directly to the patient via the same nasal cannula or oxygen masks. However, where oxygen tanks contain a fixed amount of pressurized oxygen, concentrators collect oxygen from the surrounding air, concentrate it, and then deliver it to the patient, removing the need for replacement or refilling. Concentrators are also available in multiple styles, offering larger models for using at home or in the hospital as well as more compact models perfect for traveling and moving out and about.

There are many similarities and differences between oxygen tanks and oxygen concentrators, and each has their own benefits. Because of this, finding the right product to meet you or your loved one’s needs might feel like an imposing task. This article will review some of these key differences and similarities, offer some important tips for finding the best product to meet your needs, and introduce some of the top products on the market, helping you make an informed decision that you feel confident in. 

Pros & Cons

Oxygen tanks and oxygen concentrators have several key differences, and each are defined by certain advantages and disadvantages.

Oxygen Tanks

Oxygen tanks contain pressurized oxygen that can be continuously released at specific flow rates to provide medical grade oxygen to the patient. These devices are usually mounted on a rolling apparatus—such as a small trolley or cart—that allows them to be rolled alongside the patient. 

Pros

1. No power required. One of the most distinct advantages of oxygen tanks is that they take advantage of the pressurized oxygen within them to operate. By releasing the oxygen at one of several flow rate options, oxygen tanks are able to operate without requiring the use of a battery or electrical outlet. This ensures that the tank will be able to provide oxygen until its contents are depleted. 
2. Silent. Since oxygen tanks are simply delivering their contents at a specified rate, there are no beeps or loud sounds associated with using them. This makes them great for use around other people in quiet environments like movie theatres or libraries, and ideal for napping or being around others who need to remain undisturbed, like babies. 
3. Lower initial cost. Oxygen tanks are the traditional form of personal oxygen, and as such, they are often the most inexpensive, featuring the lowest initial price tag of all the different oxygen devices on the market. If the dollar amount of the initial purchase is your primary concern, oxygen tanks are probably the way to go.

Cons

1. Heavy and/or unwieldy. One of the most commonly noted disadvantages of oxygen tanks is their weight and portability. While wheel-mounted cart systems, like this one by Drive Medical, make rolling oxygen tanks simple and easy, the tanks themselves are somewhat heavy. This means that lifting the tank—for example, to put it in a vehicle or carry it up a staircase—can be challenging due to the weight of the device.
2. Limited to their contents. Oxygen tanks only contain a limited amount of oxygen, and once the tank has been depleted, it has to be refilled or replaced with a new tank. Once the oxygen within the tank is depleted, the tank must be refilled or replaced with a fresh tank. 
3. Greater cost over time. Because oxygen tanks need to be refilled or replaced frequently, their initial low price adds up over time to make their cost higher long-term. 

Oxygen Concentrators

Instead of the limited amount of pressurized oxygen used by oxygen tanks, oxygen concentrators use a filtering system to take ambient air in from around the patient, compress and modify it to medical-grade standards, and then deliver it to the patient. These devices are available in both larger home-style models and smaller portable models that are more ideal for traveling and moving around on the go.

Pros

1. Unlimited oxygen. The ability of oxygen concentrators to continuously draw in and treat air ensures that, unlike oxygen tanks, the concentrator will never run out of oxygen. This is frequently noted by customers as being one of the best features of oxygen concentrators. 
2. Lightweight. Because they do not rely on pressurized oxygen, concentrators do not require a dense metal tank. This means that they are notably lighter and more portable than most oxygen tanks. In fact, many oxygen concentrators, such as the Invacare Platinum Portable Oxygen Concentrator, are designed to be carried in a backpack or side bag for ultimate convenience. 
3. Greater versatility. Oxygen concentrators are available in a wide selection of sizes, models, and styles, each designed to perfectly accommodate a specific user base. While oxygen tanks are largely all the same, concentrators provide a greater variety of choices to ensure you get exactly what you need.
4. Up-front cost. While oxygen tanks frequently need to be refilled or replaced, oxygen concentrators use ambient air and therefore don’t require the long-term maintenance costs that tanks do. All of your concentrators costs will come up-front in your initial purchase.

Cons

1. Batteries required. Because they do not use pressurized oxygen within a tank, oxygen concentrators must rely on battery or electric power to perform their air filtering and oxygen flow. As is the case with any battery-powered device, the available charge in the battery must be considered. If the battery isn’t charged, it will eventually run out of power and the concentrator will shut down until charged again, which could be dangerous for someone who needs their oxygen at all times.
2. Noisy. Oxygen concentrators collect oxygen from the air and then filter and compress it for the user. This process can often be noisy, due to the various components at work, and this is the most common complaint that concentrator users have. Many newer concentrator models have been designed to reduce this noise to barely noticeable levels, but there is often still some amount of sound associated with their operation.
3. Expensive. Because of the complex mechanisms at work, oxygen concentrators are often quite expensive up-front. While this cost is a single purchase unlike that of oxygen tanks, many people may not be able to afford the high price tag all in one chunk even though it saves money in the long-run.

How to Choose

1. How are you going to use it?

If you’re looking for a good, solid device for oxygen therapy to use in your home, hospital room, or other facility, either a concentrator or a tank will do the job just fine. Oxygen tanks can easily move up and down the hallways of a home or facility on a mobile cart, while standard concentrators are great for more stationary uses in your bedroom or living room featuring handles or wheels for short-distance portability. 

However, if you’re planning to use your device for travel, running errands, or other more active jobs, a portable oxygen concentrator is a better solution, featuring a lighter-weight design and an array of convenient bags and cases for easy carrying.

2. How much oxygen do you need?

Oxygen tanks, specifically, come in a number of volumes. Depending on the oxygen flow rate that is recommended and the amount of time that the tank will be required, certain volumes may be better than others. However, it is important to consider that the size of the tank influences its weight: the larger the volume in the tank, the heavier it will be.

Oxygen concentrators don’t have a set capacity, so if you need a large amount of oxygen, a concentrator will most likely save you money in the long-run and probably be more convenient for you, as you won’t have to worry about constant refills and tank replacements. This high-capacity concentrator from Invacare offers more oxygen than any concentrator in our catalog, making it the perfect solution for users with high oxygen requirements.

Additionally, while most oxygen cylinders and concentrators offer a range of flow rates, it’s important to consider whether the device you finally select can offer your prescribed flow rate. Make sure you pay close attention to this particular specification when you’re comparing products.

3. How often do you travel?

If you’re a fairly stationary person, just looking for something that will accommodate you moving around a single room or home, then a compact concentrator like this one from Drive Medical is probably the best option. 

A combination of a larger oxygen concentrator like this stationary concentrator from Caire Medical, and the occasional oxygen tank might be the best solution if you’re someone who mostly stays in one place, but needs to go on short outings every once in a while.

If you’re a more active person who likes to travel, going on trips either by car or plane fairly regularly, or simply likes to engage in a more active lifestyle, then a portable oxygen concentrator like this innovative portable concentrator from O2 Concepts is the best option for you. 

4. What’s your budget?

Budget can be a very important consideration when selecting an oxygen therapy device, as it is when choosing any product. Often people may gravitate towards the lower buy-in price of oxygen cylinders, but it’s important to remember that if you have the extra money to spring for a concentrator, it will save you money over time by eliminating the need for refills and tank replacements.

Often Medicare or similar insurance systems will pay for the cost of a standard stationary oxygen concentrator, but they will often not cover the additional costs of a portable concentrator model. For this reason, a lot of people often forgo the higher price of the portable concentrator, but it can be a lifesaver if you’re someone who travels a lot or highly values the freedom to travel and engage in an active lifestyle.

5. What other components do you need?

Many oxygen tanks and concentrators come with optional transport accessories. These can be wheel-based mounts for oxygen tanks, shoulder bags, or attachments for wheelchairs. If you do not already have a device for carrying and/or transporting your oxygen device, this is something you might be interested in purchasing depending on how you intend to use your device.

Additionally, there are a number of other items that may or may not be included with your oxygen tank or concentrator that you should consider. Items like oxygen tubing, nasal cannulas, and oxygen masks are required for proper oxygen therapy delivery, so if you don’t have them already, you might be interested in a product that includes them as a bundle, or you can purchase them separately for more control over the type of tubing and mask you ultimately use.

Products like flow regulators, oxygen conservers, and other accessories may also be something to consider before making your final purchase.

If you do intend to choose an oxygen cylinder over a concentrator, you may also be interested in a storage rack for your cylinders so that you can keep multiple on hand, or a home fill system so that you can forgo the cost of a concentrator and instead save yourself money by refilling oxygen tanks yourself.

What are oxygen concentrators?

Oxygen concentrators (oxygen generators) are a type of medical device that you may use as part of oxygen therapy. If you have a condition that affects your lungs or even if you have some difficulty breathing, an oxygen concentrator helps get your body the oxygen it needs to function.

Unlike a compressed or liquid oxygen tank that you must replace or refill when you run out of oxygen, an oxygen concentrator continuously purifies the air around you (atmospheric air) to deliver 90% to 95% pure oxygen. You breathe in the oxygen through a plastic mask that fits over your mouth and nose or a flexible plastic tube with two prongs that go into your nostrils (nasal cannula).

Don’t use an oxygen concentrator unless a healthcare provider prescribes one for you. Breathing in pure oxygen can cause long-term lung damage if you don’t need oxygen.

What are the types of oxygen concentrators?

There are two main types of oxygen concentrators:

• Stationary oxygen concentrator. A stationary oxygen concentrator weighs about 22 pounds (10 kilograms). It has handles to lift the device or wheels on the bottom to roll it. It runs on electricity, so you plug it into an electrical outlet in your home. In the event of a power outage, some brands of oxygen concentrators come with a battery backup or a backup compressed oxygen tank, so you can still receive oxygen therapy until your power comes back on.
• Portable oxygen concentrator. Portable oxygen concentrators are smaller and lighter than stationary ones, allowing for easier activity or travel. But their oxygen output is usually lower than stationary oxygen concentrators. Most portable oxygen concentrators use rechargeable lithium-ion batteries.

What conditions are treated or managed with oxygen concentrators?

A healthcare provider may prescribe an oxygen concentrator if you have:

• Asthma.
• Bronchitis.
• Chronic obstructive pulmonary disease (COPD).
• Cystic fibrosis.
• Emphysema.
• Heart failure.
• Lung cancer.
• Pneumonia.
• Respiratory trauma (rib fracture, collapsed lung, bruised lung).
• Sleep apnea.

Some people, especially athletes, use an oxygen concentrator when they visit high-altitude areas. When you work out, you breathe harder because your body is trying to get more oxygen to your lungs. Your lungs supply oxygen that your body uses to function. This includes your muscles.

If you can’t get enough oxygen through heavy breathing, your cells will convert carbohydrates into lactate (lactic acid) for short bursts of energy. The name for this process is anaerobic glycolysis. Using an oxygen concentrator helps prevent your body from producing lactic acid, which helps increase energy, reduce fatigue and improve training.

How common are oxygen concentrators?

Oxygen concentrators are common. More than 1.5 million people in the United States use some form of oxygen tank as part of their supplemental oxygen therapy, including oxygen concentrators.

How do oxygen concentrators work?

The atmospheric air that most people breathe every day is about 20% oxygen. The rest is nitrogen, along with tiny amounts of other gases. Oxygen concentrators take in atmospheric air, remove the nitrogen and collect pure oxygen for you to breathe.

First, it sucks in the atmospheric air through an air filter and forces it through an air compressor. The compressor pressurizes the air — think of it like blowing air into a balloon. As the pressure increases, the air travels into special filters. Oxygen molecules are smaller than nitrogen molecules, so the filters trap the nitrogen and let the oxygen pass through into a collection tank. The oxygen then travels to an oxygen outlet and through your mask or nasal cannula.

How many hours can you get out of an oxygen concentrator?

It depends on the make, model, oxygen output and number of batteries your oxygen concentrator uses. On average, a single-battery oxygen concentrator lasts from two to six hours. The average double-battery oxygen concentrator can last between five and 13 hours.

A plug-in oxygen concentrator runs as long as you have power in your home.

How long should you be on an oxygen concentrator?

It depends on why you need supplemental oxygen. Most people must use supplemental oxygen for at least 15 hours every day. Some people need to use it 24 hours a day. A healthcare provider will direct you on how often to use it and what your output setting should be.

If you have a short-term condition, you may only need an oxygen concentrator until you recover.

If you have a long-term condition, you may need to use an oxygen concentrator for the rest of your life. A provider will work with you to help you adapt to living with an oxygen regulator. It may take some adjustments, but it shouldn’t interfere with your everyday activities, including working, bathing, exercising and traveling.

What are the potential benefits of an oxygen concentrator?

The main benefit of oxygen concentrators is that they help you breathe easier. They aren’t a cure for your condition and may not completely relieve shortness of breath. But it should be easier to breathe. Higher oxygen levels in your blood can also give you more energy and help you sleep better.

Another benefit is that, unlike other types of oxygen tanks, you don’t need to refill an oxygen concentrator. You’ll have an unlimited oxygen supply as long as you have an energy source.

What are the disadvantages of oxygen concentrators?

Oxygen concentrators must have a power source. If you use an oxygen concentrator, it’s a good idea to have at least one set of fully charged batteries or a compressed oxygen tank available in case your power goes out. You should have enough batteries or extra oxygen available for at least a few days.

Pure oxygen can also be dangerous. It isn’t flammable. But it makes fire burn hotter and faster. It can also cause an explosion. Make sure you keep your oxygen concentrator at least 10 feet away from sources of high temperatures or flammable materials, including:

• Cigarettes and cigars.
• Fires.
• Ovens.
• Grills.
• Gasoline.
• Oil.
• Paints and paint thinner.
• Rubbing alcohol.
• Oil-based products, such as petroleum jelly (Vaseline®).

You should also avoid using electrical equipment around your oxygen tank. There’s a risk that electrical equipment can spark and cause a fire. This includes items such as:
