Oxygen Concentrator FAQ's

  • What is an Oxygen Concentrator?
    • Oxygen concentrators are devices that extract oxygen from the air around us and filter it into purified oxygen for breathing. Oxygen concentrators are typically prescribed by medical professionals if you have a condition that affects your breathing. This includes conditions such as COPD, cystic fibrosis, sleep apnoea, and much more.

  • How does an Oxygen Concentrator work?
    • An Oxygen Concentrator takes in the air around us and separates it using molecular sieves, leaving behind a high concentration of around 90-95% oxygen.

  • What are the two types of Oxygen Concentrator?
    • There are two types of oxygen concentrators, a stationary/mains powered oxygen concentrator and a portable oxygen concentrator (POC). Stationary oxygen concentrators are heavier and bigger in size. They run on electricity and therefore must be plugged into an electrical outlet in your home in order to start producing oxygen. Stationary machines are able to deliver a much higher quantity of oxygen and are therefore more suited to users prescribed with a high flow rate. A mains oxygen concentrator usually delivers between 1-10 litres of oxygen per minute (LPM) Portable oxygen concentrators are much smaller and lighter. This type of concentrator uses rechargeable lithium-ion batteries to function, making it the perfect option when it comes to travel.

  • What is a Portable Oxygen Concentrator (POC)?
    • A portable oxygen concentrator is a Lithium Battery operated device that helps people who have difficulty breathing on their own or who suffer with Pulmonary Fibrosis or other respiratory conditions to get the oxygen they need. It is a small machine that works by taking in air from the surrounding environment and converting it into concentrated oxygen for the user to inhale. Typically a Portable Oxygen Concentrator can deliver between 0.5 LPM and up to the equivalent of 6 Litres per minute.

  • How Does a Portable Oxygen Concentrator Work?
    • A Portable Oxygen Concentrator works by filtering and purifying the air, removing nitrogen and other gases to increase the oxygen concentration. The concentrator then delivers this purified oxygen to the user, usually through a nasal cannula or an oxygen mask.

  • What is the difference between a Pulse Flow and a Continuous Flow (Constant Flow) Oxygen Concentrator?
    • Portable Oxygen Concentrators deliver oxygen to a user via two different methods, pulse flow and continuous:
      Pulse Flow
      All small, lightweight Portable Oxygen Concentrators use this type of flow, with flows settings equivalent to 1-6 LPM (Litres per Minute) i.e.1-6 settings. This type of oxygen machine can only be used with a nasal cannula.
      This type of Concentrator typically weighs around 2-4 KG in weight and is worn on the shoulder or carried separately.
      Unfortunately, there is a large patient population who cannot use this Pulse technology.
      When using a portable machine with pulse delivery, this means that you only receive the oxygen every time you begin to take a breath.
      If it’s very quiet and someone is near your nose each time you breathe in, they could actually hear it give you a puff of oxygen as you inhale.
      Continuous Flow
      A Constant or Continuous flow can be one of 2 types of machine:
      1. A Portable battery-operated Concentrator giving usually supplying 0.5-3 LPM flow.
      This type of Continuous Flow Portable Concentrator typically weighs around 8-10 KG in weight and is usually supplied on a trolley for the user to pull around.
      2. 2. Or a "static" or mains operated Oxygen Concentrator using a wall plug in your Home or Cruise Cabin
      This device is providing you with oxygen in a constant flow, meaning if you took off the nasal cannula and put it in a glass of water, the water would bubble.
      A Mains driven Oxygen Concentrator will provide an oxygen flow of between 1 and 10 LPM (Litres per Minute).
      A Constant or Continuous flow Oxygen Concentrator can be used with either a nasal cannula or a face mask.

  • Who should use a Pulse Delivery?
    • Pulse delivery is designed for adults, not normally children; specifically, it is prescribed to adults who breathe an average of 12 to 18 times a minute.
      Pulse Flow Concentrators are designed to operate on a setting based on 15 to 18 breaths per minute as equivalent to the litre flow and relationship to the chosen setting. For example the setting of two on pulse at 15 to 18 breaths a minute could be equal to 2 Litre per minute of flow based on the volume of each dose (Bolus).
      If the adult is a mouth breather, meaning perhaps they have a nasal septal defect and cannot breathe normally through their nose and typically are always only breathing through their mouth, or maybe someone with a very shallow breath, this type of patient is not a candidate for pulse delivery, however, most adults that breathe normally through their nose tend to do quite well with a pulse dose POC.
      Children breathe much faster than adults, therefore pulse or on demand flow technology should not normally be used with a child unless approved by your Respiratory Specialist or Doctor. The child will breathe faster than the equipment can make the oxygen, therefore potentially putting the equipment into alarm.
      Doctors do not recommend using a pulse flow oxygen machine when sleeping. When we sleep, it is very natural for people to start breathing out of their mouth

  • Do Oxygen Concentrators run out of Oxygen?
    • Unlike Oxygen cylinders, concentrators do not have a finite amount of oxygen. As long as the machine has power, whether that be through a mains outlet or a lithium battery, the concentrator will continue producing oxygen for the user.

  • Are Oxygen concentrators noisy?
    • One of the biggest concerns many people have when purchasing or renting an oxygen concentrator is the level of noise the machine will make. In general, most oxygen concentrators vary in the level of sound they make, ranging from 30 decibels to around 50. This can be compared to the volume of a quiet whisper or a quiet conversation.

  • I use a CPAP or a BIPAP machine at night to help me breath, what kind of Oxygen Concentrator do I require?
    • If you use a CPAP or a BIPAP machine you can only use a constant flow oxygen concentrator, this can be either a portable constant flow, or a mains driven stationary concentrator, if you advise us of your oxygen flow requirements we will have a machine that suits your needs.

    • Yes, VAT exemption is available on Oxygen Concentrators for all eligible UK customers.



Fit to fly FAQ

  • Do I need proof I'm fit to fly if I have a medical condition?
    • If you have a medical condition such as Asthma, COPD, Pulmonary Fibrosis, Lung Cancer, you’ll want to ensure that you’re fit to fly before travelling abroad, it’s always worth checking in with your doctor or nurse so that they can get a better understanding of your condition before you commit to flying. You might find that there are circumstances where you will need an official fit-to-fly certificate.

  • Are there restrictions on flying?
    • There are some long-term medical conditions that can flare up occasionally. As well as making you feel unwell, a flare-up of Asthma, COPD, Pulmonary Fibrosis, Lung Cancerand other conditions can make travelling much riskier.
      If you have a long-term medical condition, you should always check with your or airline whether you’ll need a fit-to-fly certificate or medical letter confirming you’re currently fit to fly, failure to do this can mean that the Airline may not allow you entry onto the plane.

  • Why do I need Oxygen on the Flight?
    • One of the major issues in relation to fitness to fly is the fact that oxygen pressure in a plane is lower than on the ground. This means conditions affecting your heart and lungs, which can reduce your body's ability to carry oxygen around your body, can lead to worsening symptoms during your flight.In some situations, you may be able to fly if you have access to Portable Oxygen on the plane You will definitely need a letter from your doctor detailing:
      • All your medical conditions.
      • Why you need to travel with oxygen.
      • That your condition is stable and that you are fit to fly with oxygen.
      Remember that all airlines have different rules about travelling on a plane with oxygen,many Airlines no longer supply it on board for free which is where The Oxygenstore can help.

  • Can I take my NHS supplied Oxygen Concentrator out of the UK?
    • No, you cannot take your NHS oxygen concentrator out of the UK because the UK oxygen providers do not allow their equipment to be taken outside the UK. However, you can arrange to rent or hire a portable oxygen concentrator from The Oxygenstore for delivery to your home before you fly.

  • How much does it cost to get a fit-to-fly certificate?
    • This depends on how much your GP surgery charges - but typically this cost ranges from £25-£50. There are also a number of Independent Medical Professionals that can organise aa Fit to Fly test at short notice.
      You can find a list of suggested fees from The British Medical Association.

  • Can I get travel insurance with COPD or Respiratory Conditions?
    • Yes, once you declare Chronic Obstructive Pulmonary Disease (COPD) as a condition, you can compare a range of quotes for specialist COPD travel insurance policies.
      Therefore, it’s important that you declare COPD as part of your medical history. Once you do this, you’ll need to answer a few specific questions related to your condition.
      You’ll be asked how much medication you’ve been prescribed to manage your breathing condition, how many hospital admissions you’ve had in the last year, how short of breath you get after a certain distance, and previous medical screenings, if your medicines are prescribed away from the hospital if you’ve ever been a smoker, and if you’ve had pneumonia or any other chest infection in the last year.

  • Can I fly with severe COPD?
    • Depending on which Chronic Obstructive Pulmonary Disease condition you suffer from, whether it is bad emphysema or severe bronchitis – you need to consider the fact that this automatically puts you at a higher risk while flying.
      This is because the more severe the condition is, the more likely there are to be complications. in most cases, people are fine to fly as long as they have a supplementary oxygen supply in the form of a Portable Oxygen Concentrator available on the flight itself.
      Here you would need to notify the airline that you require special considerations to be made on your behalf. It’s also wise to talk all of this through with your doctor before making any definitive travel arrangements.

  • Can I fly long haul with COPD?
    • Firstly, consider whether you’re fit to fly altogether, a 12-24 hour long haul flight is much more physically demanding versus a 2-3 hour short haul flight.
      A major factor to consider with a Long Haul Flight is that the oxygen pressure in an aircraft cabin is lower at high altitudes than it is on the ground. If you’re not short of breath when you exercise (for instance, when you walk fast or when you go uphill) this shouldn’t affect you.
      However, even for healthy people, the difference in oxygen levels at about 8000 feet means the average oxygen saturation in your blood could drop to about 90% or lower. If you already suffer from shortness of breath due to your COPD, its likely, your oxygen levels aren’t as high as they could be. And if these drop further at altitude, you could run into major problems, this is why you may need a Portable Oxygen Concentrator (POC).
      If you feel fit and healthy and a flight is manageable – discuss with your doctor the possibilities of flying long-haul and the risks that this may present. This is all dependent on which specific lung condition you suffer with.
