Optimizing Patient Care

NKV-550 Series Ventilator System

The NKV-550 Series Ventilator System is a comprehensive neonatal through adult mechanical ventilator.

It features an intuitive and customizable app-based platform providing clinicians with the tools to individualize lung protective strategies. The ability to transition patients between invasive, non-invasive ventilation and high-flow oxygen therapy with one device reduces hospital costs and clinician's time.

Lung Protection Tools

Gentle Lung® Suite

Recruitability Assessment

Provides clinician insight into patient's lungs to help determine if a recruitment maneuver could be beneficial.

Recruitment Maneuver

Customized stepwise lung recruitment maneuvers enable clinicians to focus on the patient's condition.

PEEP Titration

Continuation of recruitment maneuver or independently initiated to help determine PEEP at best compliance.

Transpulmonary Pressure App

The Transpulmonary Pressure App monitors the transpulmonary pressure to help individualize a lung protective treatment strategy.

Lung Protection Tools

Adaptive Ventilation Mode* (AVM)

An optional tool, allowing the ventilator to auto-adapt to the patient's respiratory status.

Smoothly auto-transform the patient between full ventilatory support and spontaneous ventilation as set by the clinicians.

Automatically monitor the patient's respiratory status to either wean or escalate ventilatory support, while limiting driving pressure for

lung protection.
