What is SOS Oxygen?


SOS Oxygen is the UK's leading independent supplier of medical oxygen cylinders, providing a low cost, customer service focused supply throughout England, Scotland, Wales, and Northern Ireland.


Through our customer service focussed approach, we support healthcare professionals providing a lifeline to patients.

Our Responder O2 range of medical oxygen cylinders from SOS Oxygen incorporates the latest design and technology, featuring a '1 switch' operation to turn the cylinder on and select oxygen flow rates in a single movement.

The new '1 switch' design makes our Responder O2 cylinders the fastest, most reliable and easy to use medical oxygen cylinders on the market.

In addition to medical oxygen cylinders, Speciality Oxygen Service (SOS) also specialises in the supply of Nitronox cylinders, an effective pain relief system containing analgesic gas composed of 50% medical nitrous oxide / 50% medical oxygen.

This analgesic gas mix is commonly referred to as Entonox, however Entonox is BOC’s registered trademark for their product. Our Nitronox and BOC’s Entonox are the same gas products/mixes but manufactured and supplied by separate companies under different trademarks and product licenses.

SOS Oxygen is the UK's fastest growing supplier of Nitronox cylinders and medical oxygen cylinders.

Our 2.7L Responder O2 emergency medical oxygen cylinder is compliant with CQC and Resuscitation Council guidelines for dental practices. The 2.7L Responder O2 cylinder contains 579 litres of medical oxygen which is more than the minimum guideline requirement, making them ideal for GDC dental requirements.

You'll receive an annual cylinder report to download for your records, including barcode details of the types and quantities of medical oxygen and Nitronox cylinders on your account, plus batch numbers and expiry dates. The annual cylinder reports detail all the information you'll require for CQC inspections.

There's no need to call us when your cylinders' gas expiry dates are due to expire, our digital asset tracking system continuously monitors all of our cylinders and we'll be in touch to arrange replacement cylinders, free of charge, before your medical gases expire.

Callouts and deliveries are carried out by your personal account manager who will liaise directly with you to arrange visits to your site.

What is Medical Oxygen and What is it Used For?


Oxygen is critical to life, in fact, almost all living things, including humans, need oxygen to survive.


Oxygen typically makes up 21% of Earth's atmosphere and oxygen also makes up around half of Earth's crust in the form of oxides.

The importance of medical oxygen in the field of healthcare is vital, it is used every day in healthcare for resuscitation and inhalation therapy, in fact, it is believed to be the most common treatment given in hospitals in the developed world.

The potential value of oxygen for patients with respiratory conditions was quickly recognized after its discovery in 1771 by Carl Wilhelm Scheele, a German-Swedish pharmaceutical chemist.

The 20th century saw a rapid succession of discoveries of oxygen's physiologic effects and technological advances that allowed its clinical application.

Today, medical oxygen is on the World Health Organization's list of essential medicines and modern medicine could not be practiced without the support of medical oxygen.


Medical oxygen is used to:
  • Carry out cardiopulmonary resuscitation (CPR)
  • Restore tissue oxygen tension by improving oxygen availability in a wide range of conditions such as COPD, cyanosis, shock, severe hemorrhage, carbon monoxide poisoning, major trauma, cardiac/respiratory arrest
  • Provide life support for artificially ventilated patients
  • Carry out anaesthetic techniques
  • Aid cardiovascular stability


Contraindications/side effects: There are no absolute contraindications to the use of medical oxygen but the inspired concentration should be limited in the case of premature infants and those patients with chronic bronchitis and emphysema.

British Thoracic Society (BTS) guidelines on the safe therapeutic use of medical oxygen encourages proper assessment of the patient before use. The target oxygen saturation recommended depends on the condition being treated.



What Makes Oxygen Medical Grade?


In the UK, medical oxygen manufacturers and distributors are licensed by the MHRA.


The manufacturing process of medical oxygen is closely monitored, controlled, and documented to ensure the quality and purity of the medicine meets quality standards for pharmacopeia.

All cylinders which are filled with medical grade oxygen display a product label which lists details of the medicine and the manufacturer, including licence details and contact details.
