Occupational exposure to nitrous oxide during procedural pain control in children: a comparison of different inhalation techniques and scavenging systems.
Nitrous oxide (N2O 50% in oxygen) is commonly used for painful procedures in children.
Potential negative health effects associated with chronic workplace exposure limit its use. Safe occupational N2O exposure concentrations are below 25 ppm environmental concentration as a time‐weighted average (TWA) and below 200 ppm as a short‐time exposure level (STEL) of 15 min. … (continua)
