Birth Labor

Nitrous oxide

Nitrous oxide, commonly called laughing gas, is a 50/50 mix of nitrous oxide and oxygen that you inhale through a mouthpiece during contractions. It does not eliminate pain but takes the edge off and helps you feel calmer and more in control. You breathe it in about 30 seconds before a contraction peaks, so timing matters. It leaves your system within minutes, meaning it does not affect your baby or your ability to push. Some women feel dizzy or nauseous at first. It can be combined with other pain relief methods, and you remain fully mobile throughout labor.

What This Means for You

Understanding Nitrous oxide is an important part of your labor journey. When preparing for birth, understanding this term helps you discuss your birth preferences with your midwife or OB-GYN and know what to expect in the delivery room.
