(A) NO2 levels were measured after passage through the Ca(OH)2 scavenger while the mini-NO generator produced 40 ppm NO in an airflow of 70 ml/min. The pediatric ventilator was set to deliver 50% O2, VT=18 ml, RR=40 bpm (n=3 measurements/time point). The dotted line indicates 1 ppm of NO2. (B) While the mini-NO generator produced NO at 20, 40, or 80 ppm for 24 hrs, the 0.8 g Ca(OH)2 scavenger maintained the level of O3 below the 80 ppb level recommended by OSHA over a 24 hrs period. (C) While the mini-NO generator produced NO at 40 ppm with FiO2 at 21, 50, 80, and 100%, and gas flow at 1 L/min, the scavenger maintained the level of O3 at less than 1.5 ppb for all FiO2 levels tested (n=3–4 measurements/time point).
