Gas and air is also known as Entonox
What is gas and air?
Gas and air is a mixture of gases (nitrous oxide and oxygen) which you breathe in whilst you are having a contraction. This can help to relieve some of the pain you are experiencing and can also help you focus on your breathing – supporting you to feel calm and in control. You can use it in combination with any other type of pain relief.
Will it work for me?
All pain relief options vary in how effective they are – what works for someone else may not work for you. Gas and air does not remove all pain, but it can help to reduce it and make it more bearable. It can be used in combination with other forms of pain relief if it is not working effectively on its own – your midwife can discuss what other options are available to you.
When is gas and air the most effective?
Gas and air can be used to provide pain relief once you are in established labour. You can then continue to use gas and air until the birth of your baby.
How do I use it?
During a contraction, you breathe in the gas and air through a mouthpiece which you hold yourself. It takes 15-20 seconds to work, so it is better to take slow deep breaths, starting just as a contraction begins. Once the contraction is over, you can remove the mouthpiece and breathe in fresh air. This is continued throughout your labour with each contraction, controlled by you. Most people like it because it is easy to use and you are able move around whilst using it.
Are there any side effects for my baby?
There are no known harmful side effects for your baby.
What other things should I consider?
There are no known harmful side effects for you although it can make you feel light headed. Some people find that it makes them feel sick, sleepy or unable to concentrate. It can also cause you to have a dry mouth – we will encourage regular sips of water to help.
If you begin using the gas and air and find that you experience any side effects, you are free to stop using it. Any side effects that you are experiencing will wear off within seconds of breathing fresh air.
How many times can I use it?
You are free to use the gas and air as much or as little as you like once you are admitted in established labour. However, to be most effective we would recommend using it with every contraction and not using it in-between. Continuous breathing of the gas and air can prevent it from working effectively.
Will I still be able to have a water birth?
Gas and air is suitable to be used during a water birth.
Where is it available?
Gas and air is available for all vaginal births in the Newcastle Birthing Centre and the Delivery Suite. It is also available for home births – speak to your community midwife for more information.
