Humming Vue

“Piston Based” HFO – Unique Benefits

Although there are different types of HFO ventilators available today, the piston-type oscillator is considered the most gentle and the safest approach to manage the respiratory needs of challenging patient scenarios, especially to treat the lungs of premature newborns. Piston ventilators have the advantage of delivering accurate tidal volume while supporting active expiration.

Metran is the only company in the world that has successfully realized the piston-type HFO ventilator.

HFO ventilation in Humming Vue is gentler to the lungs

• Humming vue produces pure sinusoidal waveform making it the only true oscillator in the newborn and pediatric market.
• Capable of supporting patient weight from 300 gms to 35 Kg.
• HFO pressure waves are sinusoidal and symmetrical with respect to the mean airway pressure (MAP) axisproducing active expiratory phase thereby ensuring rapid CO₂ elimination along with effective oxygenation.
• Mean airway pressure is not affected by changes in the tidal volume and also remains stable during spontaneous breathing.
• Humming Vue is the only volume generating ventilator which produces a precise stroke volume (SV) at the source to obtain a specified amplitude pressure (∆P). A fixed SV is guaranteed no matter how the lung compliance changes.
• Piston is precisely controlled to within 13 microns on each stroke, allowing you to set stroke volume with resolution of 0.2ml.
• Stable MAP and ability to manage PaO2 independently from PaCO2 are key features of Humming Vue.
• Auto sustained inflation feature during HFO ensures auto recruitment of alveoli.
• All conventional modes such as A/C, SIMV, APRV as well as NIV Modes such as CPAP, BiPAP , NSIPPV, High Flow Oxygen Therapy are available providing full ventilator support from intubation to weaning for neonate and pediatric patients.
