K001121 is an FDA 510(k) clearance for the OXYGEN APPLIED SYMPTOM IMPROVEMENT SYSTEM (OASIS). Classified as Chamber, Hyperbaric (product code CBF), Class II - Special Controls.

Submitted by Engineered Medical Technology, Inc. (Victoria, US). The FDA issued a Cleared decision on November 29, 2001 after a review of 601 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5470 - the FDA anesthesiology and respiratory device framework. The Abbreviated 510(k) pathway was used, relying on FDA-recognized standards to demonstrate substantial equivalence.

Device pattern: High-complexity regulatory submission. Standards-verified equivalence. 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.
