From: Modelling levels of nitrous oxide exposure for healthcare professionals during EMONO usage
Change in the time-weighted average of nitrous oxide (N2O) concentration over an 8 h period (TWA-8 h) values over time for various scenarios. In Panels (a and b), the room is considered non-ventilated, except for a door opening between successive administrations of equimolar mix of nitrous oxide (N2O)/oxygen (O2) [EMONO]. In Panels (c and d), only adult patients are considered and a door or window opening is simulated between successive EMONO administrations for the otherwise non-ventilated rooms. ODV stands for on-demand valve
