Summary

Comparisons of the components of ventilator waveform were made in two groups of preterm infants ventilated for the respiratory distress syndrome. Infants actively expiring against positive pressure inflation were compared to infants not showing this interaction. The actively expiring infants were ventilated with a higher peak inspiratory pressure (P < 0.01) and a significantly greater duration of positive pressure plateau (P < 0.05) than the control group. The two groups were well matched for gestational and postnatal age and there were no other significant differences in the components of ventilator waveform. Adoption of a ventilator waveform with a shorter positive pressure plateau and less steep rise in positive pressure might reduce the incidence of active expiration and hence pneumothoraces.

    Certain new neonatal ventilators allow the rise time to peak pressure to be varied. Physiologic data suggest a rapid rather than a slurred upstroke is more likely to provoke active expiration/asynchrony [26]. Asynchrony does occur in the population of premature infants [27].
