Does any institution currently utilize nitrous oxide for non-neuraxial labor analgesia? If so, would you be willing to share:
1. A protocol or policy and procedure used to implement the program?
2. Vendors or manufacturers utilized for the blender and scavenger systems? At this point, I think we would be more interested in a portable system as opposed to having it piped through the wall.
3. Concentration utilized for the blend: 50/50 or other? Anyone using up to a 72/25 blend?
