How Units Work

Air that is inhaled from the atmosphere is approximately 78% nitrogen, 21% oxygen and 1% other gases. An oxygen concentrator separates the nitrogen from the oxygen, allowing for the user to breathe in over 95% pure oxygen for therapy purposes. The device does this by absorbing air through the inlet filter and compressing it into one of two "zeolite towers."

The first zeolite tower consists of two cylinders with sieve beds, which become saturated by the nitrogen from the air. At this stage, a valve opens and oxygen is forced into a second zeolite tower. Excess nitrogen is then removed and any remaining nitrogen in the sieve bed is released through the ventilation system. This then leaves a purer state of oxygen to be inhaled.

This then leaves a purer state of oxygen to be inhaled.

Types of Units

There are two primary types of oxygen units, the Pulse dose unit, and continuous flow unit. A pulse dose machine delivers air to the patient in the form of short puffs. It senses when the patient is ready to take a breath, releasing the oxygen in stages as to not waste any. These units are triggered by nasal inhalations and therefore may not be as effective when the patient is asleep.

The continuous flow unit produces a steady stream of oxygen. The compressors tend to be larger for this reason, and there is the possibility of oxygen waste due to the patient not breathing in constantly. These units do not expel more than 3 liters per minute due to maintaining a balance between battery size and portability. The settings on a continuous oxygen machine allow for the user to input how many liters they want to inhale per minute, whereas a pulse machine uses a particular setting mode that is not related to liters, but to the quantity of puffs. The type of unit you&#;ll require will most often be prescribed by your health care provider.

Key Features

Once you know the type of device you need, here are the key features to consider when comparing portable oxygen concentrators.

Battery Life
Battery life is affected by how much the device is used and the setting it&#;s on. If the device is in use while traveling, a larger battery may be more appropriate, however, this tends to be heavier and less convenient. If there is an electronic outlet within a vehicle, this may be more appropriate for more mobile patients. It is always recommended to have a spare battery at all times, and when traveling via airplane, according to regulations, the battery must be able to last twice the length of flying time.

Capacity
The bigger the oxygen machine is the more output capacity it has. However, this does not mean larger units are the most convenient, especially if the user likes to travel. It is essential patients test a concentrator before committing to one.

Size
Size will be an important consideration for those on-the-go. You&#;ll want to look at the range of options available to see what is best for your needs and lifestyle. Being that these devices will have to go everywhere with you, you might want them to be as small as possible, or you may need one that is more powerful. Be sure to compare the dimensions and oxygen output of each device and consider how you will transport it.

Weight
The weight of a portable oxygen device will vary. Some units can be carried on a patient's back, while others can be wheeled along the ground. A continuous portable device weighs approximately 17 to 20 pounds whereas a pulse flow portable alternative can be anywhere from 3 to 10 pounds. You will want to compare options to see which is most manageable for your day to day life.

Noise Level
Given that the average quiet home has a decibel unit of 40 dBA, an oxygen concentrator will typically be between 37 and 43dBA. This sounds like a very low hum, much like a refrigerator or the inside of a library. Portable concentrators tend to be quieter than home-based devices primarily due to the difference in size. It can also depend on the setting of the device that is being used. Check the dBA of the units you are considering to see how loud its operation will be.

FAA Approved
An FAA approved device will be one of the safest and most reliable options when purchasing an oxygen concentrator. This is an important consideration if you plan on traveling via airplane, as airlines require FAA approved machines in order for patients to fly with them.

Warranty
To ensure that the oxygen concentrator is effective and reliable, it will have a warranty, ensuring it can be replaced or repaired by the manufacturer if there is ever an issue. The warranty will typically be 3 years although most devices have a lifespan that far exceeds this. If there is a cheaper model available without a warranty, then this adds a risk of incurring future costs of replacing the device should it break.

Brands

There are several pulse and continuous flow brands to choose from with their own individual features. Here are the top products on the market:

Respironics

POC Advantages and Disadvantages

Probably the most significant advantage of a POC is in its name; it's portable. POCs work well for patients with active lifestyles and those who love to travel. Here are some advantages of POCs:

• They're lightweight and easy to carry. POCs weigh anywhere from 5 to 10 pounds and generally come with carrying bags or backpacks, making them as easy to carry as a purse.
• POCs allow you to be your independent self. Unlike larger, stationary concentrators, POCs will enable you to do housework, run errands, have dinner with friends, and live your everyday life since carrying it with you is easy.
• You can travel with a POC. Most POCs are FAA-approved, which means you can take them and use on an airplane.
• POCs offer longer battery lives than larger home concentrators. Depending on your prescribed flow setting and the battery you're using, POCs can last several hours, some lasting up to 16 hours. Most POC batteries let you charge on the go while still allowing you to use the unit.

Overall, POCs allow for independence and are overall easy to use. However, POCs aren't for everyone. Two of the most significant disadvantages of portable concentrators relate to oxygen delivery and flow options. Portable oxygen concentrators don't generally offer as much oxygen as larger, home oxygen concentrators, so make sure your POC meets your demands if you require higher oxygen. Also, if it's continuous flow oxygen you're looking for, most POCs don't offer this option, although there are few on the market that do.

One more factor to consider is the cost. Although the upfront cost of a POC might be higher than other oxygen delivery methods, you'll save money over time. For example, oxygen tanks only hold so much gas and eventually run out and must be refilled. Since POCs utilize the air around you, they generate their own oxygen supply, as long as there's a charged battery or available power supply.

Is a POC suitable for you?

Consider these factors while researching supplemental oxygen options:

• How much supplemental oxygen do you demand? Your doctor will prescribe a flow (liters per minute) or a flow setting. A portable oxygen concentrator will likely meet your needs if you require a lower flow setting, generally under six. You might consider a home oxygen concentrator or oxygen cylinder if you have higher oxygen demands.
• Do you require continuous flow or pulse dose oxygen? As mentioned, most POCs offer only pulse dose oxygen. However, finding a POC with continuous flow is still an option if a portable device is what you're looking to use.
• Can you carry around five or more pounds? Although some manufacturers make lightweight POCs, you might want to consider a home unit if you cannot carry your machine around.
• Do you travel, and are you active? POCs offer the best option to patients who stay active or like to travel. If POCs meet your oxygen demands, you'll likely find the right POC for you.

Accessories

Certain accessories are available to make the use and transportation of a portable oxygen concentrator more comfortable. These are:

Nasal Cannula: This accessory assists with the oxygen being easily transported from the machine to the user through tubing that fits into the nose.

Oxygen Masks: An oxygen mask is ideal for a patient who have higher oxygen needs for maximum airflow.

Replacement Batteries: It is always a good idea to have a backup battery just in case something unexpected occurs. When it comes to traveling by plane, each airline has different guidelines that they adhere to regarding portable oxygen concentrators and their batteries. It is always advised to check with airlines before booking a flight. In addition to an FAA-approved device, the majority ask for the battery to last several hours longer the length of the flight, as well as requesting that spare batteries be carried by the passenger. This means that long haul, international journeys may ask for a large quantity of batteries to be brought on board.

Carrying Cases and Carts: This is useful for both portable devices and ambulatory oxygen tanks. The machines can be transported via carts and carry cases, or worn in a backpack for convenience when traveling.

Financing Options

Everyone's financial circumstances are different, so there are a range of ways to pay:

Pay Up Front
Simply put, this means paying the full cost of the machine up front before it is delivered. The device is then owned outright by the patient.

Paypal Credit
Bill me later is a credit service where the purchase does not need to be paid for immediately. This process tends to be much easier than obtaining a credit card or loan and means that payments can be made in monthly installments to suit the patient.

Choosing the Right Unit

A discussion should be had between the patient and their healthcare provider to decide on which type of portable oxygen concentrator is required (continuous or pulse dose). After the ideal dosage is prescribed, a unit can be narrowed down to fit the individual needs of the patient taking the above points into consideration. View more on
