SensorMedics 3100A Oscillatory Ventilator

The SensorMedica 3100A is a true high frequency oscillator with a diaphragmatically-sealed piston driver.  It is theoretically capable of ventilating patients up to 35 kg.  Tidal volume (TV) typically delivered ≈ 1.5-3.0 cc/kg (TV<dead space).  It is an extremetly efficient ventilator secondary to an active expiratory phase, but it is not capable of delivering sigh breaths for alveolar recruitment.

 Initial settings:

10 Hz (600 BPM) for term infants ( > 2.5 kg)

12 Hz (720 BPM) for premature infants (1.5 -  ≤ 2.5 kg)

14 Hz (840 BPM) for preterm infants ( 1.0 - < 1.5 kg)

15 Hz (900 BPM) for preterm infants < 1.0 kg
