Pain relief options

Nitrous oxide (gas)

How do I use nitrous oxide in labour?

  • you control the amount you use
  • start breathing on it as soon as you feel a contraction coming on, so you will get the full effect when the pain is at its peak
  • avoid use between contractions or for long periods as this can make you feel dizzy.

What is nitrous oxide?

Nitrous oxide is a gas that is mixed with oxygen and administered through a face mask or a mouthpiece held in the mouth.

Nitrous oxide is simple and quick to act and wears off in minutes. It will not take the pain away completely, but it may help.
