K953990 is an FDA 510(k) clearance for the TRANSFLOW TEST. Classified as Calculator, Pulmonary Function Data (product code BZC), Class II - Special Controls.

Submitted by P.K. Morgan , Ltd. (Kent Rainham Me8 7ed, GB). The FDA issued a Cleared decision on December 9, 1996 after a review of 473 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.1880 - 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: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Anesthesiology submissions.

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.
