I am sorry, but the provided text does not contain the detailed information necessary to answer your request about acceptance criteria and a study proving device performance. The document is an FDA 510(k) clearance letter for the Atrium Medical Corporation Express™ Chest Drain, indicating that the device is substantially equivalent to legally marketed predicate devices.

The letter lists the indications for use but does not include:

• A table of acceptance criteria and reported device performance.
• Details about sample sizes, data provenance, or the number/qualifications of experts.
• Information on adjudication methods, MRMC studies, or standalone algorithm performance.
• Specifics about the type of ground truth used or the training set for any AI/algorithm.

Therefore, I cannot fulfill your request for this specific document.
