Nitrous Oxide Leak detected by Portable G200

Using a G200 N₂O monitor supplied by Bedfont Scientific, a dental engineer was able to identify a leak from faulty sedation equipment in a surgery. They said: “I set the area monitor onto 'leak mode' and used it to ‘sniff’ around the machine with it set to deliver 20% N₂O at a low flow rate with the scavenger and delivery circuit connected. I found that the air intake was spewing out N₂O at an alarming rate - the readings went up to over 4,000ppm." The engineer reported their findings to the supplier of the sedation equipment who confirmed that a valve inside was most likely faulty and they would issue a replacement.

The surgery now has their own G200 monitor so they can easily keep a check on their equipment and they are planning to roll out a monitoring program to cover all of their sites in due course.
