Fig. 1

Virtual representation of a medical room, including an adult patient in supine position on a bed at the center of the room and the healthcare professional standing close to the patient’s bed. In addition are represented in two 2D-plane sections the N₂O concentration values within the room, as obtained by the numerical simulation, at one given time during the equimolar mix of nitrous oxide (N₂O)/oxygen (O₂) [EMONO] administration process, as defined in one of the considered scenarios. The red and dark blue colors are representative of the maximal and minimal computed concentrations, respectively
