Intended Use

The KoKo LEGEND is intended to be used for diagnostic use in the pulmonary function testing (PFT) with an intended use and indication for use as a configurable, non-invasive pulmonary function tester (PFT) testing system. The KoKo LEGEND is indicated for use in: pulmonary function testing.

The KoKo LEGEND (Diagnostic Spirometer) is an Office Spirometer. It is intended as a configurable, portable, noninvasive pulmonary function tester (PFT) system. These tests are suitable for both pediatric and adult patient testing.

Device Description

The KoKo LEGEND is a configurable, non-invasive pulmonary function tester (PFT) testing system. It is a diagnostic spirometer.

AI/ML Overview

The provided text is a 510(k) summary for the KoKo LEGEND Diagnostic Spirometer and does not contain detailed information about a specific study testing the device's performance against acceptance criteria in the way a clinical trial or algorithm validation study would.

Instead, it declares conformity to recognized standards and lists technical specifications, which implicitly serve as acceptance criteria for a diagnostic spirometer.

Here's an analysis based on the information available:

1. A table of acceptance criteria and the reported device performance

For a diagnostic spirometer, the "acceptance criteria" are primarily established by recognized performance standards. The device's "reported performance" is its technical specifications, which are implicitly stated to meet these standards.
