The Global Hypoperfusion Index (GHI) algorithm provides the clinician with physiological insight into a patient's likelihood of future hemodynamic instability. The GHI algorithm provides the risk of a global hypoperfusion event (defined as SvO2 ≤ 60% for at least 1 minute) occurring in the next 10-15 minutes. The GHI algorithm is intended for use in surgical or non-surgical patients receiving advanced hemodynamic monitoring with the Swan-Ganz catheter. The GHI algorithm is considered to provide additional information regarding the patient's predicted future risk for clinical deterioration, as well as identifying patients at low risk for deterioration. The product predictions are for reference only and no therapeutic decisions should be made based solely on the GHI algorithm predictions.

This FDA 510(k) summary for the Edwards Lifesciences HemoSphere Alta Advanced Monitoring Platform (K232294) primarily focuses on demonstrating substantial equivalence to predicate devices through technical comparisons and non-clinical performance validation. It explicitly states that "No new clinical testing was performed in support of the subject 510(k)." As such, the document does not provide specific acceptance criteria for AI/algorithm performance or details of a study proving the device meets such criteria through clinical data.

Instead, the submission emphasizes the device's functional and safety aspects, along with the integration of existing, previously cleared technologies and algorithms into a new hardware and software platform with an improved user interface.

Therefore, many of the requested sections below cannot be fully answered based on the provided text, as the focus was on non-clinical verification and substantial equivalence rather than new clinical performance studies for AI/algorithm features.

1. Table of Acceptance Criteria and Reported Device Performance

As per the provided document, specific acceptance criteria and detailed device performance metrics for individual AI/algorithm features (like HPI, GHI, AFM, RVP) are not detailed as part of a new clinical study for this 510(k) submission. The submission states, "No new clinical testing was performed in support of the subject 510(k)." The "Performance Data" section primarily discusses non-clinical verification.

The document states:

• "Completion of all verification and validation activities demonstrated that the subject devices meet their predetermined design and performance specifications."
• "Measured and derived parameters were tested using a bench simulation."
• "System integration and mechanical testing was successfully conducted to verify the safety and effectiveness of the device. All tests passed."
• "Software verification testing were conducted... All tests passed."

This indicates that internal performance specifications were met, but these specifications themselves are not provided, nor is the performance against them quantified in this public summary.

2. Sample Size Used for the Test Set and Data Provenance

No test set for clinical performance of AI/algorithm features is described, as "No new clinical testing was performed." The device leverages existing, previously cleared algorithms.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

Not applicable, as no new clinical test set for AI/algorithm performance is described. The AI/algorithm features leverage ground truth established in prior clearances for the predicate devices.

4. Adjudication Method for the Test Set

Not applicable, as no new clinical test set for AI/algorithm performance is described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No MRMC comparative effectiveness study is mentioned, as "No new clinical testing was performed." The submission focuses on the HemoSphere Alta platform being a new generation integrating existing Edwards technologies and algorithms with an improved user interface and hardware.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

The document does not describe new standalone performance studies for the AI/algorithm features. The AI/algorithm features (HPI, GHI, AFM, RVP) themselves were likely evaluated in standalone fashion during their original predicate clearances (e.g., K231038 for GHI). This 510(k) integrates these existing algorithms into a new platform.

7. Type of Ground Truth Used

The type of ground truth for the AI/algorithm features (HPI, GHI, AFM, RVP) would have been established during their original clearances. For this 510(k) submission, this information is not provided. Typically, hemodynamic algorithms like HPI or GHI rely on physiological measurements (e.g., direct arterial pressure, SvO2 from Swan-Ganz catheter, outcomes data related to hypotension or hypoperfusion events) as ground truth.

8. Sample Size for the Training Set

No details regarding training set sample sizes for the AI/algorithm features are provided in this 510(k) summary, as it covers the integration of existing algorithms. The training data would have been described in the original 510(k) submissions for those predicate algorithms (e.g., for Acumen HPI feature, Global Hypoperfusion Index, Right Ventricular Pressure algorithm, Acumen Assisted Fluid Management).

9. How the Ground Truth for the Training Set Was Established

As with the training set size, the method for establishing ground truth for the training set of the AI/algorithm features is not detailed in this 510(k) summary because it pertains to existing algorithms. This would have been covered in their individual predicate 510(k) submissions.
