The 3100A high-frequency oscillatory ventilator (HFOV) can decrease the risk of these complications by maintaining a constant distending pressure and normalizing the end expiatory lung volume.

The 3100A gently delivers 1 to 3ml tidal volumes to ventilate the most premature infant and delivers up to 180ml to support the ventilation of pediatric patients. It facilitates an active exhalation, which is essential at high frequency respiratory rates to prevent air trapping that may occur with passive exhalation.

3100A oscillators patented technology and a highly reliable, electromagnetically driven piston that distinguishes it from other high frequency ventilators, it permits variable I:E ratios, which are desirable for managing ventilation and reducing the risk of air trapping.
