From: Modelling levels of nitrous oxide exposure for healthcare professionals during EMONO usage
Nitrous oxide (N2O) concentration distribution in ppm at a single 2D plane located along the patient’s bed at the end of a 59 min EMONO administration phase (a and b) without any ventilation apart from window opening (a: case #4) and with mechanical ventilation of 5 vol/h (b: case #2). Data are also shown in lower panels (c and d) for the same scenarios at the end of a subsequent 40 min wash-out phase (c: window opening; d: mechanical ventilation 5 vol/h). 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
