Piston HFO/IMV ventilator for neonate and infant



High frequency oscillatory (HFO) ventilation is recognized worldwide as an effective treatment for neonates and premature infants.

  • Smaller pressure fluctuation within the thoracic frame reduces danger of tracheobronchial injury
  • Smaller pressure fluctuation in the alveoli causes less fluctuation of blood pressure and intracranial pressure
  • 0.2 mL resolution stroke volume setting allows fine control of amplitude
  • Powerful stroke of up to 160 mL during HFO meets the ventilation needs of larger patients
  • Volume and frequency can be adjusted to meet the needs of premature and pediatric patients

Easy to use

  • Large touch screen provides easy operation and easy setting changes
  • Large 15.3-inch screen clearly displays all waveforms and parameters

  • HFO, SIMV and CPAP modes provide complete respiratory care in one ventilator
  • Patient triggered ventilation (PTV) through proximal flow sensor or pressure sensor
  • Effective monitoring of pressure, flow, oxygen concentration and all important ventilation parameters
  • Three alarm priority levels with messages and alarm indicator inform the caregiver of any small change


HFO ventilation is gentler on the lungs

HFO ventilation provides sufficient and sustained exchange of gas when the stroke volume is smaller than the anatomical dead space.
HFO pressure waves are sinusoidal and symmetrical with respect to the mean airway pressure (MAP) axis. After passing through the endotracheal tube, the amplitude of the HFO pressure wave falls drastically upon entering the trachea so there is minimal pressure variation at the airway periphery near the pulmonary alveoli.
Compared with continuous mandatory ventilation (CMV), HFO ventilation has much less pressure swing at any mean airway pressure and this greatly reduces physical injury to the pulmonary alveoli
