The air that we breathe contains around 21% Oxygen with the remaining majority made up of mostly nitrogen and other gases that the body doesn't need. An Oxygen concentrator takes in this air and separates it through a row of molecular sieves which contains a non-hazardous chemical, leaving a high concentration of Oxygen of around 90%.

The Portable Oxygen Concentrators we stock are all different. They vary in size, weight, battery life, warranty length, how much each machine is capable in delivering oxygen and more. We offer both on demand and continuous flow concentrators.At Intermedical, we consider these factors when recommending you a Portable Oxygen Concentrator

Suitability - Judging by your prescription, we can tell which units would be suitable and which are not.

The Long Term - Unfortunately Chronic lung conditions such as COPD & Emphysema are progressive meaning flow rates can change as time goes on. We ensure the Portable Oxygen Concentrator we recommend will be potentially suitable for use in the long term as well as now.

Your happiness - We do not forget why you came to us in the first place. Your freedom and independence are our priority. To ensure this happens, we will try our best to recommend a solution that is not only suited to your needs for the short and long term but to enable the freedom of doing things you couldn't do before.

All Portable Oxygen Concentrators we supply deliver oxygen to the patient using On-Demand flow, also known as Pulse Flow via the use of a nasal cannula. This is where a patient gets a "shot" of oxygen every time the portable oxygen concentrator detects inhalation. The amount of oxygen inhaled within that "shot" works out to be around the same if you were inhaling on a continuous flow oxygen concentrator.

Most portable oxygen concentrators that run an "on-demand" oxygen system have settings which are approximately equivalent to the litre per minute selected on the device.

Continuous flow oxygen is delivered at a constant rate irrespective of the user’s breathing rate as the name suggests.

All on demand devices have an alarm to monitor and increase your safety during use.Use of an on demand portable oxygen concentrator during sleep is entirely dependent on your personal circumstances.The use of a continuous flow oxygen concentrator is always suitable.

When a patient is diagnosed with COPD or Emphysemasevere respiratory condition the capability of lungs to exchange oxygen into the blood stream may be reduced. When this happens, the heart needshas to work harder increasing the and the risk of cardiac arrest and blood clotting. is high. An Oxygen concentrator is used to provide the body with a much higher than normal concentration of Oxygen per breath to compensate for any reduced lung functionality.

The answer is no. However, oxygen is a prescribed drug and we recommend you are seeking medical / clinical advice should you wish to purchase an Oxygen concentrator.

As a responsible medical supplies company, we will only supply patients who are existing users or currently seeking advice.

If you suffer from Sleep Apnoea, you will no doubt be using a CPAP, BiPAP or another ventilator system whilst sleeping overnight. You can only use a continuous flow oxygen concentrator whilst sleeping if you suffer from Sleep Apnoea.

This is possible however it does depend on the model concerned. Please contact us and we can advise you.

This varies depending on the model but will be typically 3 years for the device and 1 year for any accessories.
