What is Carbon Dioxide?

Carbon dioxide is a high grade gas made of 100% Carbon dioxide. It is a non-flammable, colourless and odourless gas. It is liquefiable under pressure, with refrigerant properties in the liquid phase and is supplied in cylinders as a liquid under its own vapour pressure of approx. 5,000kPa at 15C.

Uses and Applications

Medical Carbon Dioxide is used with anaesthetics. This is to make sure your blood levels of Carbon Dioxide are satisfactory so that you breathe easily during surgery. Medical Carbon Dioxide also makes you breathe in deeply so that the anaesthetic is rapidly effective and stays effective throughout the surgery. Medical Carbon Dioxide can be used to stimulate your breathing if you stop breathing or if your breathing has been obstructed in some way, but is now cleared. Medical Carbon Dioxide can also be used to calm your breathing if you are over-breathing (hyperventilation).

  • Sedation or Anesthesia/Analgesia
  • Breath stimulation and regulation

Complementary Products

For carbon dioxide use in your practice we have a number of products that are useful in the implementation of this gas. Our Series O Carbon Dioxide regulator by Comweld is a very popular regulator for a portable bottle system. Alternatively if you are going to have your gas piped in to the surgery then the self sealing gas outlet is ideal for the wall fixture option.
