K840645 is an FDA 510(k) clearance for the ENGSTROM ELIZA DUO CO2 & O2 ANALYZ. Classified as Analyzer, Gas, Oxygen, Gaseous-phase (product code CCL), Class II - Special Controls.

Submitted by Gambro, Inc. (Mchenry, US). The FDA issued a Cleared decision on April 5, 1984 after a review of 50 days - a notably fast clearance cycle.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.1720 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
