K933285 is an FDA 510(k) clearance for the DATEX AS/3 TM ANAESTHESIA MONITOR. Classified as Gas-machine, Anesthesia (product code BSZ), Class II - Special Controls.

Submitted by Datex Division Instrumentarium Corp. (Helsinki, FI). The FDA issued a Cleared decision on November 14, 1994 after a review of 496 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5160 - 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.
