When inhaled, the gaseous combination of nitrous oxide and oxygen acts as an anesthetic and analgesic during medical and dental procedures – such as oral surgery – as well as during childbirth and trauma treatment. The medical use of nitrous oxide-oxygen in...
As humans, we breathe oxygen to survive. Though it makes up little more than 20% of the air we breathe (the majority of which is nitrogen), oxygen is vital to the proper functioning of our bodies – our hearts and brains included. Oxygen is required for cell...
