K122539 is an FDA 510(k) clearance for the MEASUREMENT OF PH IN PLEURAL FLUID ON BLOOD GAS SYSTEM. Classified as Electrode Measurement, Blood-gases (pco2, Po2) And Blood Ph (product code CHL), Class II - Special Controls.

Submitted by Siemens Healthcare Diagnostics (Norowood, US). The FDA issued a Cleared decision on April 19, 2013 after a review of 241 days - an extended review cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1120 - the FDA in vitro diagnostics and chemistry 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. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.
