Nitrous oxide during labor: how does it work?
'Laughing gas' offers light, fast pain relief that's entirely controlled by the person giving birth.
Nitrous oxide, mixed in equal parts with oxygen, is inhaled through a mask or mouthpiece that the person in labor holds and uses on their own, usually at the start of a contraction, with the peak effect kicking in about 30 to 50 seconds later.
Unlike an epidural, it doesn't fully block the pain, but it helps you relax and tolerate it better by slightly altering perception. Its big advantage is that its effect fades quickly (within minutes) once you stop inhaling, with no lasting effect on mother or baby.

It's not offered everywhere — availability varies by facility and region. If this option interests you, it's worth checking ahead of time whether it's offered at your planned place of birth.
