You breathe in the Entonox gas through a mouthpiece which can control how much pain relief you have. This pain relief method does not make the pain completely disappear.
Entonox is easy to use and is available in hospital and home birth settings. It can be used the same time as other pain relief methods and there is no danger of taking too much. This method can make some people feel sick.
Your midwife will advise you on how to effectively use Entonox.
