source quote (p.4)
“The Acumen Hypotension Prediction Index Feature (DEN160044) consists of software running on the Edwards Lifesciences EV1000 Clinical Platform (DEN160044) and HemoSphere Advanced Monitoring Platform (K180881) paired with the FloTrac IQ or Acumen IQ extravascular blood pressure transducer (K152980) and a radial arterial catheter. The software includes the Acumen Hypotension Prediction Index (HPI), the Dynamic Arterial Elastance Parameter (Eadyn), the Systolic Slope Parameter (dP/dt), and additional graphical user interface features.”
AlgorithmAn index related to the likelihood of a patient experiencing a hypotensive event (defined as mean arterial pressure (MAP) < 65 mmHg for at least one minute in duration) within 15 minutes, where zero (0) indicates low likelihood and one hundred (100) indicates high likelihood.

FDA source did not state a quantitative performance metric — non-reporting is itself the signal.

Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.

drift signals on this device

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.

Reimbursement — how devices like this got paid

Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).

Applicable FDA guidance — what the submission is measured against

FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Cardiovascular panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.

Applicability is derived from the device's FDA advisory panel and pathway — cross-cutting guidances apply to every AI/ML device; panel-specific ones are flagged. Titles, dates, and links verified against fda.gov as of July 2026.
