FDA PRODUCT CODE · CLASS II
NOU — Continuous, Ventilator, Home Use
This product code was needed for the home use indication. CBK is not a tracked device and NOU is a tracked device.
What these counts are not
Clearance and recall counts are SPEQ’s aggregation of FDA’s own published records for the code. A recall count is a measure of history, not of a device’s safety, neither number is an FDA rating, and SPEQ is not affiliated with the FDA.
What this classification requires
Every statement below is FDA’s own classification record for this product code, quoted from the device classification field reference. The SPEQ reading beneath each one is SPEQ’s interpretation of what it means for the work, and is not FDA text.
510(K)
SPEQ READINGA premarket notification under 21 CFR Part 807 Subpart E is the route for this code. The submission argues substantial equivalence to a legally marketed predicate, so the engineering question is which predicate the design can actually be compared against, and the evidence question is what testing supports that comparison.
Class II (moderate to high risk): general controls and special controls
SPEQ READINGSpecial controls are the distinguishing feature: performance standards, guidance documents, patient registries or postmarket surveillance named for the device type. Find the special controls before designing the test plan — they usually name the tests.
Device is not eligible for The Voluntary Malfunction Summary Reporting Program
SPEQ READINGIndividual malfunction reporting under 21 CFR Part 803 applies. The complaint-handling system has to produce a decision per event, not per period.
Not exempt due to Good Manufacturing Practice (GMP)/Quality System
SPEQ READINGThe full Quality Management System Regulation (21 CFR 820, incorporating ISO 13485:2016) applies, and is what an FDA inspection of this device will be conducted against.
Device is not implantable
SPEQ READINGNo implant-specific expectations attach from the classification itself.
Device is used for life sustaining purposes.
SPEQ READINGA life-sustaining designation is what brings device tracking under 21 CFR Part 821 into scope, and it raises what a risk file has to say about single-fault conditions.
Device is not a candidate for a third party review program
SPEQ READINGFDA reviews any premarket notification for this code directly.
Other product codes under 21 CFR 868.5895
One regulation usually governs several product codes. These share this code’s regulation, and therefore its classification basis.
21 CFR 868.5895 — Continuous ventilator
The classification regulation for this product code, as published by the Office of the Federal Register. This is the regulation text itself — no SPEQ interpretation appears in it.
(a) 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.
(b) Classification. Class II (performance standards).
