Intended Use
The Nihon Kohden NKV-550 Series Ventilator System is intended to provide continuous ventilation for adult, pediatric and neonatal patients who require invasive or noninvasive respiratory support. The NKV-550 offers mandatory and spontaneous ventilation modes as well as respiratory monitoring. The NKV-550 is intended for use in hospitals and hospital-type facilities, as well as, for in-hospital transportation.
Device Story
NKV-550 Series Ventilator System provides continuous respiratory support via invasive or non-invasive modes. System comprises graphic user interface (GUI) and breath delivery unit (BDU). GUI allows clinician parameter setting (tidal volume, inspiratory pressure), alarm configuration, and waveform/loop monitoring. BDU utilizes microprocessor-controlled pneumatic system with proportional valves to deliver oxygen (21-100%) and medical air. Device supports A/CMV, SIMV, and SPONT modes; includes new Adaptive Ventilation Mode (AVM), Adaptive Trigger (ATRIG), and Adaptive Cycle (Acycle) software features. Used in hospitals and for in-hospital transport by healthcare professionals. Output provides mechanical ventilation and real-time respiratory monitoring to assist patient breathing; aids clinical decision-making through automated breath delivery and alarm management.
Clinical Evidence
No clinical data. Substantial equivalence demonstrated via bench testing, software verification, device functionality testing, human factors/usability testing, and risk management/regression analysis. Compliance with ISO 80601-2-12 requirements for critical care ventilators confirmed.
Technological Characteristics
Continuous ventilator; AC/DC power; proportional valve pneumatic system; microprocessor-controlled. Features AVM, ATRIG, and Acycle software. Meets ISO 80601-2-12. No material changes to gas path; biocompatibility unchanged.
Indications for Use
Indicated for adult, pediatric, and neonatal patients requiring invasive or noninvasive respiratory support for continuous ventilation.
Regulatory Classification
Identification
A continuous ventilator (respirator) is a device intended to mechanically control or assist patient breathing by delivering a predetermined percentage of oxygen in the breathing gas. Adult, pediatric, and neonatal ventilators are included in this generic type of device.

#### Dear Sheryl Higgins:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

### Device Description
The Nihon Kohden NKV-550 Series Ventilator System consists of a graphic user interface (GUI) and a breath delivery unit (BDU). The GUI allows clinicians to set ventilator control parameters such as tidal volume and inspiratory pressure, to set alarm limits such as high inspiratory pressure alarm, to view monitored numeric values, to view waveform and loops, and to operate various features through the apps.
The BDU contains a microprocessor that receives inputs from the electronic system and controls the pneumatic system for breath delivery to the patient. It also provides various alarms, a safety valve, and other design features to maximize patient safety.
### Product Intended Function
The Nihon Kohden NKV-550 Series Ventilator System is intended to provide continuous ventilation using medical oxygen and external sources of compressed medical air to deliver oxygen concentrations of 21% to 100%. Ventilatory support is intended to be delivered invasively or non-invasively to patients who require Assisted/Control Mandatory Ventilation (A/CMV), Synchronized Intermittent Mandatory Ventilation (SIMV) or Spontaneous Ventilation (SPONT).
## Indication For Use (Intended Medical Indication)
The Nihon Kohden NKV-550 Series Ventilator System is intended to provide continuous ventilation for adult, pediatric and neonatal patients who require invasive or noninvasive respiratory support. The NKV-550 offers mandatory and spontaneous ventilation modes as well as respiratory monitoring.

Image /page/6/Picture/0 description: The image features the logo of NIHON KOHDEN. The logo consists of a stylized blue graphic on the left, resembling a stylized mountain range or waveform. To the right of the graphic, the text "NIHON KOHDEN" is displayed in a bold, sans-serif blue font. The overall design is clean and corporate, suggesting a professional and established organization.
The differences between the modified Nihon Kohden NKV-550 Ventilator System and the predicate device (k192307) are as follows:
- The subject device adds a breath mode, Adaptive Ventilation Mode (AVM), as well 1. as Adaptive Trigger (ATRIG)/Adaptive Cycle (AcycLE). These are software-only features that do not require any new hardware.
The differences between the modified Nihon Kohden NKV-550 Ventilator System and the secondary predicate device (k193228) are described in section 12 – Substantial Equivalent Discussion.
In conjunction with AVM and Adaptive Trigger (ATRIG)/Adaptive Cycle (AcYCLE), this 510(k) brings FDA up-to-date on non-significant changes implemented since the last 510(k) clearance. Therefore, the following modifications are included:
- 1. Mechanical Hardware changes
- 2. Software Revision History changes
- 3. Labeling changes
Device modifications were made in compliance with Design Control procedures.
