Fig. 4

Nitrous oxide (N2O) concentration distribution in ppm at a single 2D plane located along the patient’s bed (pediatric patient) at the end of a 59 min EMONO administration phase (a and b) without on-demand valve (a: case #7) and with on-demand valve (b: case #9). Data are also shown in lower panels (c and d) for the same scenarios at the end of a subsequent 15 min wash-out phase (c: case #6; d: case #8; double-door opening in both cases). The red and dark blue colors are representative of the maximal and minimal computed concentrations, respectively. Note the different scale for color depiction of N2O concentration in lower panels
