Home Oxygen Concentrator For Sale And Rental

Home Oxygen Concentrator is a medical device that helps to pure fresh oxygen to the patient through a nasal cannula or mask. The concentrator device brings in the air from the surroundings and compresses it. The compression eliminates the nitrogen through a filter and sieve beds, resulting in leaving 87%-95% of pure oxygen only in the air. This pure oxygen is then delivered to the patient that needs it.

Who Needs a Home Oxygen Concentrator?

An oxygen concentrator is a device specially designed to help patients with breathing problems. It's worth noting that breathing problems can be caused by a number of conditions, including but not limited to Coronavirus, asthma, and lung disease. Other disease culprits are cystic fibrosis and chronic obstructive pulmonary disease (COPD), which affects nearly 16 million individuals around the globe. These breathing conditions can be treated or managed through oxygen therapy and that's where oxygen concentrators come in handy.

Advantage of A Home Oxygen Concentrator

If you have seen and use the traditional oxygen cylinder you will know that it is bulky and dangerous, ugly too. Can you imagine you still have to carry around those heavy, ugly and unwieldy oxygen cylinders around?

A home oxygen concentrator is designed to be used at home and it is safer and also much more cost-effective. A traditional oxygen cylinder has a limited oxygen supply. You need to replenish it when it runs out. A home oxygen concentrator will never run out of oxygen as it draws the air from the surrounding. 

The patient does not have to worry about running out of oxygen in the midst of oxygen therapy. Unlike the traditional cylinder tanks, you do not have to worry about leakage. And of course, it is much nicer in design and you can carry it around easily, even when traveling in airplanes.

There are 2 types of Oxygen Concentrators:

Stationary Oxygen Concentrators

The key difference between a stationary oxygen concentrator and a portable one is size and weight. Stationary oxygen concentrators are bigger and much heavier compared to the stationary device. The larger size also enables the device to deliver a high flow rate, at 3 to 10 liters compared to the portable device 1 to 5 liters of oxygen per minute. Stationationary concentrator is recommended for the patient that needs substantial oxygen supply.

Portable Oxygen Concentrators (POC)

Portable oxygen concentrator - This oxygen therapy device is lightweight and portable enough to be easily carried around. A portable oxygen concentrator offers oxygen therapy to those on the go and needs a higher level of oxygen concentration than the normal ambient air level. This small oxygen therapy device is particularly useful if you need to travel. It can be carried on-flight. FAA allows FAA-approved portable oxygen concentrators to be carried by travelers on US airlines.

Due to differences in the needs of oxygen in the body during day and night, POCs have been configured to operate in two different modes -

Pulse dose generators

These are mostly used for day time activities. These are small units, with some of the smallest weighing around 5 to 7 pounds. As the name suggests, the main mode of operation is by giving the patient oxygen is small doses, in intervals. A pulse dose POC is frequently used in conjunction with a nasal cannula.

A nasal cannula is a lightweight oxygen delivery system. It is usually made of light tubing, with two prongs that are placed in the nostrils. The cannula is used by patients who need supplemental oxygen but can breathe by themselves. They are made specifically for the purpose of delivering low volumes of oxygen.

Continuous flow generator

Continuous flow POCs are for much heavier uses of oxygen. They are usually large and their nitrogen scrubbers are usually larger than those found on pulse does POCs. This type of POC is best for those who need oxygen as they sleep.
Due to the continuous nature, they are usually larger, weighing close to 20 pounds. This is because of the larger molecular sieve and other electronics that will be bundled with the generator.

Patients who require this type of generator can utilize either a nasal cannula, or in the more serious cases, can use a Non-Rebreather Mask. This is a mask designed for patients who need oxygen in higher concentrations.

They work by using a one-way valve to deliver air to the patient. There is a bag attached that is first filled with oxygen before the patient can use it. As the patient breathes, they inhale air from this bag, at which point the POC will replenish the oxygen in the bag. They cover both the mouth and the nose.

As the patient exhales, the air is expelled through another one-way valve that prevents re-inhalation of expelled air, and air from the environment as well.

Benefits Of A Portable Oxygen Machine.

An oxygen concentrator offers a number of advantages to the user. Unlike previous gas cylinders, POC are not prone to rupturing or leaking. Oxygen is a highly flammable gas and one spark is all it will need to cause a disaster.

The other advantage of POCs is their portability. No longer does the patient have to be tethered to their home or their hospital bed. The P in POC is exactly why these generators were developed. Portability. Now, students can attend classes and lectures without having to worry about their oxygen saturation statistics.

As POCs work to “manufacture” their oxygen, they can last considerably longer than oxygen delivered in tanks. The portability, longevity and reduced costs make a portable oxygen concentrator a better medical decision than any other form of oxygen delivery system.

What Exactly Is A Portable Oxygen Concentrator And How Does POC Work?

For a number of years, people with respiratory and other diseases and condition requiring oxygen therapy had to go to a hospital or use high pressure delivery systems in order to get the treatment they needed. From the 1970’s, manufacturers like Union Carbide pioneered systems that could generate oxygen for patients while at home.

These systems were meant to operate without the need for frequent hospital visits, or oxygen deliveries to the home. Changes in service from a free service model to payments on a monthly basis spurred development of the concentrator system for the express purpose of cutting costs.

Early in the 21st Century, manufacturers began working on portable systems as technological advancements had made it easier to achieve desired sizes. Early models had issues with reliability but later models have immensely improved on that.

Portable oxygen concentrators are also known as oxygen supply generators. These are medical devices that are to be used by people who require high concentrations of oxygen than what is available in free, ambient air. This is for people who have less than normal saturation of oxygen in their blood.

How Do Portable Oxygen Concentrators Work?

In simple terms, a concentrator receives air from the environment, purifies and separates other gases from oxygen, and then delivers the oxygen to the patient. How it works though is the more fascinating part of these machines.

It works by utilizing a process known as Pressure Swing Adoption. When gases are put under pressure, they tend to get absorbed by the solids around them. Different gases tend to be attracted to different types of solids. This is how gases can be separated.

When a POC is powered, it sucks in air and forces it through a compressor. This compressor will then force the air to pass through a system of filters known as molecular sieves. The work of molecular sieves is to separate different types of molecules by allowing the required type of molecules to pass or be absorbed while the unwanted ones are left behind.
In the case of a POC, the molecular sieve in operation is known as Zeolite.

It is a filter made of material that nitrogen is attracted to. A brief refresher, free air is made up of 78 percent Nitrogen, 21 percent Oxygen and 1 percent of other gases.

The compressor will then force the air to pass through this Zeolite. As a result of the pressure, the Zeolite will then absorb large quantities of nitrogen than it does oxygen. The oxygen is then pressurized to 20 Psi. At this point, the oxygen and small amounts of other gases are released into another reservoir that equalizes pressure.

As the pressure reduces, nitrogen is ejected from the Zeolite. The valve between the two chambers closes and the nitrogen is then released into free air. Most of the oxygen becomes available for the patient to use, however, a little is fed back into the first chamber to remove any nitrogen from the Zeolite. This prepares it for the next round of compression and separation.
