K925085 is an FDA 510(k) clearance for the ESCORT SPIROMETER. Classified as Spirometer, Diagnostic (product code BZG), Class II - Special Controls.

Submitted by Vitalograph , Ltd. (Lenexa, US). The FDA issued a Cleared decision on August 12, 1993 after a review of 309 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.1840 - 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.
