The main philosophy behind Nihon Kohden's NKV-550 is Treasure Every Breath®: every breath matters. Our goal is to provide clinically relevant innovations and solutions for patients requiring mechanical ventilation therapies.

Seamless care

With NKV-550, patients can seamlessly switch between invasive and non-invasive ventilation as well as high-flow oxygen therapy. It is also designed to be used for patients of any build.

Lung protection

NKV-550 was built with lung safety during ventilation in mind and is equipped with the Gentle Lung® suite of applications to provide clinically relevant and easy-to-use tools for the open lung approach strategy.

Protective Control®

Protective Control® provides clinicians with a second secure and fully functional user interface to easily implement necessary changes to ventilator settings when treating patients with contagious diseases or undergoing a radiology procedure.


The NKV-550 system can transfer critical patient ventilation data to the hospital information system for data analysis and recording purposes.

Workflow optimization

NKV-550 offers highly customizable screen configurations that allow the ventilator to be tailored to various needs. Our app-based design provides guided processes to help clinicians operate more easily and systematically and optimize care for their ventilator patients.

Low operating costs

The NKV-550 system requires simple and inexpensive preventive maintenance every six months.
