A universal nitric oxide delivery system.
A nitric oxide delivery system for adult ventilators has been developed; this is designed to maintain a constant inspired nitric oxide concentration of 16 volumes per million (vpm) in spite of changes in minute and tidal volumes. In a laboratory test the system maintained tracer gas concentrations equivalent to nitric oxide 13.8-18 vpm for tidal volumes of 500, 700 and 900 ml, ventilator rates of 10, 15 and 20 b.p.m., peak inspiratory flow rates of 30, 40 and 50 litre min-1 and square, sine and decelerating ramp flow profiles.
