K222466 is an FDA 510(k) clearance for the AirTom. Classified as Ventilatory Electrical Impedance Tomograph (product code QEB), Class II - Special Controls.

Submitted by Bilab (Seongnam-Si, KR). The FDA issued a Cleared decision on June 30, 2023 after a review of 318 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.1505 - the FDA anesthesiology and respiratory device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Anesthesiology review framework, consistent with the majority of Class II 510(k) submissions.

Device Classification

Product Code QEB Ventilatory Electrical Impedance Tomograph
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 868.1505
Definition A Ventilatory Electrical Impedance Tomograph Is A Prescription Non-invasive, Non-radiological Ventilatory Device That Provides An Assessment Of Local Impedance Variation Within A Cross-section Of A Patient’s Thorax.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Anesthesiology devices follow this clearance model.
