Based on the provided text, the document is a 510(k) clearance letter for the "Jostra Venous Hardshell Cardiotomy Reservoir VHK 4200." This document primarily addresses regulatory clearance and substantial equivalence to a predicate device, rather than a detailed study report demonstrating performance against specific acceptance criteria for an AI/ML powered medical device.

Therefore, the requested information regarding acceptance criteria and a study proving device performance (especially in the context of AI/ML devices) is not available in the provided text.

Specifically, the document does not contain:

1. A table of acceptance criteria and reported device performance.
2. Information on sample sizes, data provenance, or test sets.
3. Details on experts used for ground truth, adjudication methods, or ground truth types.
4. Information on multi-reader multi-case (MRMC) comparative effectiveness studies or standalone algorithm performance.
5. Details on training set sample size or how ground truth for training was established.

The document asserts that the device is "substantially equivalent" to legally marketed predicate devices, which is the basis for its clearance, rather than presenting a de novo performance study against new acceptance criteria.
