Nitrous Oxide is most commonly prepared by careful heating of ammonium nitrate, which decomposes into nitrous oxide and water vapor. The addition of various phosphates favors formation of a purer gas at slightly lower temperatures.
Medical Use
- Used as anaesthetic and analgesic agent.
- It acts synergistically when combined with other inhaled or intravenous anaesthetic agents. It has little effect on respiration and circulation during anaesthesia.
