Designed for neonates, premature infants, and pediatric patients with birth weight ≥200 g. Delivering full-cycle precision ventilation protection - from lung recruitment preparation through ventilator weaning assessment.
The VN8HFO is a comprehensive neonatal ventilator engineered for critical care environments. It covers every key clinical intervention from pre-intubation lung recruitment preparation through to post-stabilization weaning assessment, with 17 ventilation modes and 5 exclusive patents providing complete respiratory protection.
Precise Volume Control
Stable Ventilation
Seamless Full-Cycle Care
Ultra-Quiet Operation
The VN8HFO supports 17 ventilation modes covering the full spectrum of neonatal respiratory needs - from conventional pressure and volume control modes through high-frequency oscillation (HFO, PC-HFO) and non-invasive high-flow nasal cannula (HFNC) therapy.
Five synergistic patents build a complete safety and precision framework — from oscillation mechanics to trigger synchronization and airway cuff management. Each patent targets a distinct clinical challenge in neonatal ventilation.
Industry-leading volume guarantee high frequency ventilation technology with tidal volume as low as 0.1mL, providing a ventilation safety net for the fragile lungs of neonates.
Patented diaphragm oscillation system with rolling motion + special weight component design, realizes higher frequency, smoother and quieter oscillation output, suitable for premature infants and infants with low lung compliance.
Provides four trigger modes of flow, volume, pressure and abdomen, accurately matches the infant's spontaneous breathing, optimizes synchronization timing, and greatly reduces patient-ventilator asynchrony.
Continuously monitors and automatically maintains stable ETT cuff pressure, reduces airway mucosal injury and the risk of ventilator-associated pneumonia.
Automatically compensates for the respiratory resistance caused by endotracheal intubation, reduces the infant's work of breathing, and improves ventilation comfort.

Pre-ventilation precision setup — ensuring accurate airway pressure delivery and lung recruitment
Contraindications：Sputum suction, O₂ therapy, Spontaneous breathing without sedation.
Facilitates reopening of collapsed alveoli and prevents secondary lung collapse from low tidal volume ventilation.
*Pediatric ONLY, not for neonatal use.
Before initiating invasive ventilation, configure tube resistance compensation to ensure accurate pressure delivery at patient’s airway.
Ensures pressure at tube end matches ventilator settings, compensating for resistance in endotracheal/tracheostomy tubes.

Multi-dimensional safety protection and real-time adaptive circuit management during ventilation
Apnea Ventilation Backup
Neonatal Sensor Backup
During high-frequency ventilation modes requiring continuous pressure monitoring and safety interventions.
During ventilation, the system automatically compensates for unexpected circuit or mask leaks that compromise tidal volume delivery and trigger accuracy, with a maximum leak compensation flow of 45 L/min in pediatric mode.

Objective assessment of lung function recovery and ventilator weaning readiness
Contraindications：When patient condition improves, assess readiness for ventilator weaning with objective parameter trends.
Mode: PSV O2%, ΔPsupp, PEEP, Duration & Endurance timers
Auto-terminate indicator
Enables assessment of pulmonary function recovery, lung recruitment effectiveness, and guides PEEP optimization.
After stabilization, assess lung function and ventilation strategy effectiveness through FRC measurement.

VN8HFO employs three intelligent triggers (Flow / Pressure / Abdominal) to seamlessly synchronize with spontaneous breathing, enabling precise identification of each respiratory phase and optimizing human-machine interaction for superior patient comfort.
Applicable to Dual-limb NIV and Invasive Ventilation Modes
In non-invasive single-limb mode, a pressure generator is required.
