Associated with an increase in general health and reproductive problems
What is the effect of nitrous oxide on cobalamin (Vitamin B12)?
Prevents it from acting as a coenzyme for methionine synthase
What is the primary method used for detecting nitrous oxide in ambient air?
Infrared (IR) Spectrophotometry
Why is the scavenging mask system important during nitrous oxide administration?
To prevent leakage of nitrous oxide into the ambient air
