Oximeter, Tissue Saturation

What Is FDA Product Code MUD?

Oximeter, Tissue Saturation is FDA product code MUD, Class 2, 21 CFR 870.2700.

How Does It Reach the US Market?

A 510(k) premarket notification is required before it is sold in the United States: the applicant shows the device is substantially equivalent to one already on the market. The review can be done by an FDA-accredited third party, which is usually faster. No clearance under this code names a Chinese applicant.

A registration is not a clearance: the plants above are set up to make it, and the 510(k) it is sold under is held by whoever files it, often the brand.

What Has Gone Wrong With It?

The FDA has recorded 6 recalls under this product code since 2009. None was by a company in China. The root causes the FDA records most often are Software in the Use Environment (2), Process design (2) and Device Design (1).

A recall is a fact about one product and its maker, not a grade for every manufacturer of the type.
