AirSep Focus Portable Oxygen Concentrator Review

AirSep Portable Oxygen Concentrator Reviews by

If having a lightweight, portable oxygen concentrator is essential to you, then the Airsep Focus is unquestionably an alternative you ought to consider. Weighing just 1.75 pounds, it's the littlest concentrator that we looked into, making it an incredible choice for clients with a functioning way of life or who basically don't need a massive oxygen conveyance framework overloading them. Regardless of being light, it is additionally smaller, estimating 6.4 inches tall, 4.8 inches wide and 2.5 inches down. The gadget accompanies a conveying case that has a customizable shoulder tie for included convey ability and solace. 

Tragically, one of the drawbacks of being little and lightweight is that this individual oxygen concentrator does not come with a large enough battery. Even though two lithium particle batteries accompany it, it only stays on for around three hours, contingent upon the stream rate setting you have to utilize. It likewise accompanies both AC and DC control choices for charging through an outlet. The majority of the batteries are effectively battery-powered and can be back up to full limit in around four hours.

You can buy extra batteries, if necessary, which will surrender you to 3.5 extra hours. Notwithstanding, this isn't merely one more battery lump you use to supplement the main one that came with the concentrator — it's a pack that is worn around your abdomen with a Velcro tie. Be that as it may, the tie makes it simple to convey and gives you a little expanded run time in case you're going on a journey orn trip. FAA certifies the gadget affirmed so that you can utilize it on traveler flights. 

The Airsep Focus is a heartbeat stream concentrator and won't work for individuals who need a persistent stream. It gives little blasts of oxygen to every breath you take and runs unobtrusively at around 41 decibels (which is equivalent to about a murmur). You can likewise kill the framework on or with the flick of a switch that is situated on the power string.

With its minimal, lightweight form, the Airsep Focus is an excellent portable oxygen concentrator choice for dynamic clients. Its little size makes it simple to go with; however, its battery isn't as enduring in contrast with different models. 

Types of Compact Oxygen Concentrators

Nonstop stream compact oxygen concentrators: The most widely recognized sort of oxygen concentrator conveys a constant flow of oxygen to clients (home oxygen concentrators are constantly persistent stream units). It conveys up to 3,000 mL of oxygen for every moment. It weighs between 10 and 20 pounds. It is best suited for patients who require 2— 5 liters of oxygen for each moment. Consistent stream machines are heavier than heartbeat stream units and are suggested for use when sitting still or dozing. 

Heartbeat portion compact oxygen concentrators: With heartbeat portion units, oxygen is conveyed to the client discontinuously, in customary spurts dependent on the patient's breathing rate. It conveys an oxygen stream of between 450 mL to 1,250 mL of oxygen for each moment. It has a weight of between 2 and 10pounds. It is best suited for patients who require under 2 liters for every moment of oxygen. Since heartbeat portion units are lighter than nonstop stream compact oxygen concentrators, they are prescribed for progressively dynamic clients. 

How Do Portable Oxygen Concentrators Work?

Before the 1980s, patients requiring oxygen treatment principally depended on pressurized oxygen tanks. While these tanks are very compelling, they are likewise genuinely wasteful; providers must visit patients all the time to renew the oxygen supplies in their tank(s). Patients paid providers for each home visit until the mid-1980s, when Medicare initiated a level month to month rate for these administrations. Following these changes, durable medical equipment (DME) industry started advancing oxygen concentrators to oversee costs. 

Oxygen concentrator units were at first tall, large and stationary. Versatile oxygen concentrators were acquainted in the mid-2000s with help patients when they were far from their homes. 

As the table underneath gets clearer, versatile concentrators have some advantage over pressurized oxygen tank frameworks. One drawback of portable concentrators is that their working time isn't up to that of the length of oxygen tanks when the gadget can't be connected to an outlet and must keep running on batteries. 

You should note that oxygen concentrators can easily cause fire hazards. You should never smoke when using concentrators, and the gadget should be kept in a cool, dry spots. It should also never be kept close to combustible synthetic substances and general sources of heat in your home.

Concentrators use a procedure known as 'weight swing adsorption.' Solid surfaces adsorb all gases under certain pressurized settings, yet the rate of attraction to different surfaces under certain pressurized settings vary for every gas. In particular, concentrators contain zeolite minerals that draw in nitrogen at a higher rate than oxygen. At the point when the concentrator takes in air, these zeolite minerals basically trap and contain nitrogen, which can be unsafe to people when breathed in, while a part is known as an 'atomic strainer/ molecular sieve' permits filtered, oxygen-rich air to go through the concentrator and into the client's breathing mechanical assembly. Concentrators are intended to conveyance oxygen at certain immaculateness levels, more often than not between 87% to 96%. 

Concentrators work utilizing the accompanying four-advance procedure: 

  • The concentrator attracts outside air. 
  • The concentrator packs the air; the gadget is outfitted with a cooling system to keep it from overheating 
  • Zeolite minerals draw in and contain the nitrogen, while oxygen goes through the sub-atomic sifter. 
  • Decontaminated oxygen is passed through the client's facial contraption, which ordinarily appears as nasal tubing or a face veil. 

Clients can modify the air current rate through the gadget's worked-in interface. Most portable concentrators can convey oxygen at a rate of up to a few liters per minute (LPM) under the persistent stream setting. Moreover, they may choose the 'beat stream' setting that possibly conveys oxygen when the patient is breathing in. Since the beat stream is considerably more economical than the constant stream, the wind current rate ordinarily runs from one to six LPM, and a few models have up to nine heartbeat stream settings. Higher LPM rates will deplete the battery faster, yet this is a non-issue when the concentrator is connected to an outlet. Additionally, if you don't mind note that some concentrator models do without the constant stream totally and just element beat stream settings. 

The normal standard concentrator weighs somewhere in the range of 2 and 6 pounds, however, some may weigh 20 pounds or more. Most models list temperature and moisture or humidity level at which the gadget can be worked and put away. Moreover, concentrators won't work appropriately at specific heights; the most extreme rise is typically 10,000 feet or higher. This figure is critical for deciding if a concentrator is reasonable for air travel; however, clients ought to likewise guarantee the item has been endorsed for use on planes by the Federal Aviation Administration (FAA). 

Who Uses Portable Oxygen Concentrators?

Ailments that may require oxygen treatment from a concentrator include: 

  1. Bronchitis: This issue is described by irritation in the air passages that lead to bodily fluid generation. Bodily fluid development can make air passageways tighter thereby making it hard to sleep. 
  2. Emphysema: Human lungs contain air sacs that expand like inflatables when you breathe in and flatten when you breathe out. Emphysema is attributed to harmed air sacs that can't swell and flatten properly, frequently prompting unending shortness of breath.
  3. Constant obstructive pneumonic turmoil: Also known as COPD, this issue is basically a mix of bronchitis and emphysema. Much of the time, COPD is brought about by constant smoking. 
  4. Pneumonia: Pneumonia is a contamination of the lungs that can prompt a high fever and endless hacking. In sound grown-ups, pneumonia side effects regularly clear up inside a long time — yet the condition can be intense, and here and there lethal, in patients with compromised immune systems, for example, youthful kids and the old. 
  5. Asthma: The inflammation of air passageways is the major cause of asthma and its characteristic properties include wheezing, coughing and chest narrowing. Asthma patients generally need an inhaler to prevent asthma attacks. 
  6. Bronchopulmonary dysplasia: Also known as BPD, the vast majority build up this lung disease amid early stages; usually in untimely infants. The condition might be deep-rooted and can prompt long haul breathing issues. 
  7. Congestive heart failure: Heart failure moderates the movement of blood all through the body, which results in inadequate oxygen stream. This condition is viewed as the leading medical issue among elderly citizens in the U.S.; almost 700,000 individuals are determined to have congestive heart disappointment every year.
  8. Cystic fibrosis: This unending long-lasting condition makes thick bodily fluid gather all through the body, including the lungs and aviation routes. Breathing trouble is a typical indication of cystic fibrosis.
  9. Sleep apnea: Sleep apnea is a problem caused by a brief loss of breath amid rest. Obstructive sleep apnea (OSA) is brought about by a physical obstacle that limits the airway route and makes breathing increasingly troublesome, while central rest apnea (CSA) happens when the cerebrum can't send the best possible signs to muscles that control relaxing. Individuals with apnea may encounter loss of breath over 100 times each night, yet most scenes just last a couple of moments. 

Regardless of the patient's condition(s), doctors will assess him/or her to decide whether oxygen treatment is the most reasonable treatment strategy. They may attract a blood test to quantify the oxygen levels in the patient's blood or utilize a heartbeat oximeter, which estimates oxygen levels without requiring a blood test. Also, doctors search for the accompanying side effects of low blood-oxygen levels: 

  • Quickened pulse 
  • Interminable shortness of breath 
  • Fast breathing
  • Chronic hacking or wheezing 
  • Perspiring/sweating

Low blood-oxygen levels regularly require oxygen treatment. The average grown-up has a blood oxygen focus that sits somewhere in the range of 75 and 100 millimeters of mercury (mmHg); individuals with a blood oxygen grouping of 60 mmHg or less are regularly recommended oxygen treatment. A few patients require steady oxygen treatment amid the day and night, while others get treatment on a semi-visit or as-required premise, for example, after exercises. 

Oxygen Concentrators vs. CPAP and BiPAP Machines

Like concentrators, CPAP machines convey a consistent stream of oxygen to people at a fixed, recommended rate. The air is cleaned in the focal unit and afterward conveyed to a face cover or nasal tubes utilizing a connective cylinder. BiPAP machines use a comparative system, yet rather than conveying ceaseless air at a fixed rate, these gadgets convey oxygen at a variable rate contingent upon the client's breathing examples. 

The major thing that makes concentrators and CPAP/BiPAP machines different from each other is the kind of air that patients get from either of them. Concentrators convey cleaned, concentrated oxygen that is useful for individuals with the conditions mentioned above. CPAP and BiPAP machines, then again, give a surge of air that grows the throat muscles and keeps the airways clear. Thus, CPAP and BiPAP machines are quite often recommended for people with obstructive rest apnea; they are not used to treat different maladies or conditions. 

Be that as it may, people with certain ailments — for example, OSA and COPD — may utilize a concentrator and a CPAP or BiPAP machine at the same time.

Frequently Asked Questions About Portable Oxygen Concentrators

What does a Portable Oxygen Concentrator do?
