The provided document is a 510(k) premarket notification for the Fresenius Medical Care 5008X Hemodialysis System, which includes the machine, Diasafe filters, 5008X Bloodlines, and CitraSure disinfectant. This type of document is a submission to the FDA to demonstrate that a medical device is substantially equivalent to a legally marketed predicate device.
It does not describe a study that uses a test set with ground truth established by experts to prove the device meets specific acceptance criteria in the context of an Artificial Intelligence (AI) or machine learning algorithm.
Therefore, I cannot provide the requested information, as the document does not contain details about:
- A table of acceptance criteria and reported device performance for an AI/ML algorithm. The "Key Performance Specifications/Characteristics" table (Table 4) lists engineering specifications for the hemodialysis system components (e.g., flow rates, temperature ranges, filtration efficiency for the Diasafe filter, mechanical properties of bloodlines), not performance metrics for an AI system.
- Sample size used for the test set and data provenance: This is relevant for AI/ML validation, which is not described.
- Number of experts used to establish ground truth and their qualifications: Not applicable as there's no mention of expert-labeled ground truth for an AI/ML system.
- Adjudication method for the test set: Not applicable.
- Multi-reader multi-case (MRMC) comparative effectiveness study: Not conducted as this is not an AI/imaging device.
- Standalone (algorithm only) performance: Not applicable.
- Type of ground truth used: Not applicable.
- Sample size for the training set: Not applicable, as this is not an AI/ML model.
- How the ground truth for the training set was established: Not applicable.
The document focuses on demonstrating substantial equivalence to predicate devices through various engineering tests, biocompatibility testing, electrical safety, software verification, and human factors validation for a hemodialysis system, not an AI/ML-driven diagnostic or therapeutic device.

Brief Written Description of the Device 5.4.4.
The 5008X Hemodialysis Machine provides hemodialysis treatment by controlling and monitoring both the dialysate circuit and the extracorporeal blood circuit. The machine pumps blood from the patient's body through an extracorporeal circuit, one component of which is the dialyzer. The dialyzer contains a semi-permeable membrane that uses diffusion to transfer toxins and ultrafiltration to transport excess water from the blood into the dialysate circuit. In this separate dialysate circuit, the dialysate concentrates are mixed with purified water, heated, degassed, filtered (Diasafe filters) and delivered to the dialyzer. Substitution fluid can also be delivered to the patient using the Bloodline if hemofiltration (HF) or hemodiafiltration (HDF) is being performed. Balancing chambers control the dialysate during treatment. During treatment, the extracorporeal blood circuit is monitored for venous and arterial blood pressures as well as for the presence of air and blood. The 5008X Hemodialysis Machine accommodates the following accessory devices and options:

§ 876.5860 High permeability hemodialysis system.
(a)
Identification. A high permeability hemodialysis system is a device intended for use as an artificial kidney system for the treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration. Using a hemodialyzer with a semipermeable membrane that is more permeable to water than the semipermeable membrane of the conventional hemodialysis system (§ 876.5820), the high permeability hemodialysis system removes toxins or excess fluid from the patient's blood using the principles of convection (via a high ultrafiltration rate) and/or diffusion (via a concentration gradient in dialysate). During treatment, blood is circulated from the patient through the hemodialyzer's blood compartment, while the dialysate solution flows countercurrent through the dialysate compartment. In this process, toxins and/or fluid are transferred across the membrane from the blood to the dialysate compartment. The hemodialysis delivery machine controls and monitors the parameters related to this processing, including the rate at which blood and dialysate are pumped through the system, and the rate at which fluid is removed from the patient. The high permeability hemodialysis system consists of the following devices:(1) The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (K
uf ) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or anther method of ultrafiltration control to prevent fluid imbalance.(2) The hemodialysis delivery machine is similar to the extracorporeal blood system and dialysate delivery system of the hemodialysis system and accessories (§ 876.5820), with the addition of an ultrafiltration controller and mechanisms that monitor and/or control such parameters as fluid balance, dialysate composition, and patient treatment parameters (e.g., blood pressure, hematocrit, urea, etc.).
(3) The high permeability hemodialysis system accessories include, but are not limited to, tubing lines and various treatment related monitors (e.g., dialysate pH, blood pressure, hematocrit, and blood recirculation monitors).
(b)
Classification. Class II. The special controls for this device are FDA's:(1) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Device—Part I: Evaluation and Testing,’ ”
(2) “Guidance for the Content of 510(k)s for Conventional and High Permeability Hemodialyzers,”
