K931473 is an FDA 510(k) clearance for the IMPACT MODEL 753. Classified as Ventilator, Emergency, Powered (resuscitator) (product code BTL), Class II - Special Controls.

Submitted by Impact Instrumentation, Inc. (West Caldwell, US). The FDA issued a Cleared decision on December 30, 1994 after a review of 646 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5925 - 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.
