What is Obstructive Sleep Apnoea?
People with Obstructive Sleep Apnoea (OSA) are unable to sleep properly. Their sleep is constantly disrupted by snoring and obstructed breathing to the extent that they briefly stop breathing. This can happen several hundred times each night. Sufferers often fall asleep during the day even whilst working or driving.Obstructive Sleep Apnoea is caused by excessive narrowing of the throat during sleep. Anything that makes the throat narrower to start with (for example enlarged tonsils or a set-back lower jaw) means that it is easy for the throat to close off a bit more and block the airway. A partially blocked nose generates lower pressures in the throat whilst taking a breath in, which tends to suck the walls of the throat together.Probably the most important factor is being overweight with a big neck. Extra fat in the neck squashes the throat from outside, particularly when the throat muscles become floppier with sleep.Central Sleep Apnoea is slightly different, in this variant the brain forgets to breath during sleep.

Who has Obstructive Sleep Apnoea?
It is estimated that about 80,000 people in Britain suffer from OSA. They are mostly (but not all) men, mostly (but not all) overweight, especially around the neck, and they all snore. They feel tired and sleepy during the day and at night are often observed to stop breathing.The sort of person we see most commonly with heavy snoring and sleep apnoea is a middle aged man, usually taking a size 17 collar or more. However, there are many patients with sleep apnoea who are not particularly overweight. In some patients we simply do not understand why they have sleep apnoea. In children the commonest cause is enlarged tonsils. Nowadays sleep apnoea is a common reason for recommending that a young child has a tonsillectomy. Sleep apnoea and heavy snoring, severe enough to interfere with sleep quality, is probably much more common than is realised. At least three in every thousand men have severe sleep apnoea.

What are the Symptoms of Obstructive Sleep Apnoea?
Because sleep can be so disrupted by the body having to wake up briefly to reverse the upper airway obstruction, sufferers experience severe daytime sleepiness. To start with this occurs only during potentially boring activities such as reading, watching television or driving on motorways. However, when the sleepiness gets worse it begins to interfere with most activities, with patients falling asleep talking or eating. Poor work performance can lose the sufferer his job and of course sleepiness whilst driving can be fatal (sleep apnoea sufferers are about seven times more likely to have car accidents). Snoring will usually have been present for many years, and have gone well beyond a joke within the family. There are many other symptoms that one would predict in someone seriously sleep deprived (irritability for example) but the twin symptoms of snoring and daytime sleepiness are the best pointers to the diagnosis.

What is oxygen therapy?
The therapy is recommended by physicians to patients suffering from ailments where proper supply of oxygen is hampered. It is particularly seen in cases of lung disease, cancer, or heart problems. Oxygen therapy becomes an essential for such patients as it is very important for oxygen to be properly circulated and distributed in the blood. The amount of time a patient spends on the therapy greatly varies.

How do Oxygen Concentrators work?
The device brings into use the simple formula of pressure swing absorption. By this we mean that ambient nitrogen is absorbed by zeolite materials present in the concentrator. The absorbed gas is then released at low pressure and pure oxygen is emitted from the output. This is how it typically works: The Oxygen Concentrator is fitted with two cylinders filled with zeolite pellets. Atmospheric air is passed though the porous zeolite bed which absorbs all traces of nitrogen, and releases almost pure oxygen and other minor environmental components like argon, carbon dioxide and water vapour. Within a few seconds of its contact with the environmental air, the zeolite becomes saturated. While the first cylinder works to vent air, the second takes care of absorbing more. The cycle thus repeats itself.

Any Tips for choosing Oxygen Concentrators?

Since there are a number of companies making these concentrators, Equinox, Nidek and AirSep are the some of the leading and most trusted brands. It is also very essential to choose the device that would suit you the best. Here are a few tips to consider while buying an Oxygen Concentrator:

  • Talk to your healthcare professional and let him recommend the brand and its features that are best suited for you.
  • Speak to suppliers and manufacturers and don’t hesitate to gather as much information you can. This helps to give a clear picture of the product and the features it offers.
  • Do not take price into consideration and focus on one thing—quality!
  • Buy a concentrator that offers a little higher capacity that what you need. This would help to save money in case you would want to upgrade in future.
  • Always purchase though reputable dealers.
Oxygen Concentrators come attached with the following advantages:
  • As against oxygen cylinders, Oxygen Concentrators are safer. While the former can rupture or leak and increase combustion rate of fire, the latter is easy to use and suitable for all situations.
  • Due to Oxygen Concentrators being safe, the device can be used in military or disaster situations.
  • They are generally foolproof and can be prescribed to individuals for usage at home.
  • Since it is not a very elaborate device, it can be easily stored.
  • The system is very easy to use. You just have to plug it into any electrical outlet and the device starts functioning.
  • The device also comes with the advantage of its unique ability of converting ambient air into oxygen. By doing so, the system needs no refilling.
  • They also come with a lot of safety. You do not have to worry about them from tilting or keeping them upright all the time.
  • Since they are easy to use, the device can be carried from one place to another without much hassle.
  • Care of Oxygen Concentrator
  • Caring for your device and disinfecting it at regular intervals prevents any kind of infection. Cleaning the equipment is easy. The only catch here is to clean it in a dust and smoke free room where there are no open windows. Follow this procedure weekly:
