A.362 Nitric oxide delivery after the ventilator can result in peak concentrations of 300 ppm

Distribution of inhaled nitric oxide during sequential and continuous administration into the inspiratory limb of the ventilator

“…According to the internal diameter of the tube, this volume corresponded to a sampling distance of 5 cm. Therefore, even if the maximum NO concentration was not situated exactly at multiples of tidal volume, it is highly likely that it could be accurately measured as suggested by a recent study [18]. Therefore, the fluctuation of NO concentration at sites corresponding to one and two tidal volumes was much higher than at sampling sites corresponding to half and one and a half tidal volumes (Fig.…”
