    AI/ML Overview

    The document provided is a 510(k) Pre-market Notification from the FDA for a non-automated blood pressure meter. It declares substantial equivalence to a predicate device and does not contain specific acceptance criteria, detailed study results, or performance data for the device in question ("RH non-Automated Blood Pressure Meter, MODEL Max02 and RH non-Automated Blood Pressure Meter with Stethoscope, MODEL Max0201, Max0202, Max0203").

    Therefore, I cannot provide the requested information. The document explicitly states:

    • Clinical Study: "No clinical study is included in this submission." (Page 9)
    • Performance: It mentions that "All performance specification of new devices for various cuff sizes were verified to comply with the ISO81060-1 standard." (Page 9) and "Performance compatible as requirement of ISO 81060-1" (Page 4) but does not provide the actual results or acceptance criteria from these tests. It only lists the accuracy requirement from the standard as "+/- 3 mmHg of reading."

    The acceptance criteria and study proving the device meets them are not present in the provided text. The document focuses on demonstrating substantial equivalence to a predicate device, largely through a comparison of general characteristics and adherence to recognized standards, rather than presenting a standalone performance study with detailed acceptance criteria and results.
