Overview
Acumen Hypotension Prediction Index (HPI) Feature Software Overview
The Acumen Hypotension Prediction Index (HPI) software by Edwards Lifesciences is an advanced, predictive monitoring technology designed to alert clinicians to the likelihood of a patient trending toward a hypotensive event before it occurs. Utilizing machine learning algorithms, the HPI software analyzes complex blood pressure waveform features to provide a unitless score ranging from 0 to 100, indicating the probability of hypotension (defined as mean arterial pressure < 65 mmHg for at least one minute) within a specified timeframe, typically 15 minutes.
This innovative software is integrated into Edwards’ advanced hemodynamic monitoring platforms, such as the HemoSphere system. It is compatible with both invasive arterial line monitoring (e.g., via FloTrac IQ sensor) and, with subsequent FDA clearances, non-invasive monitoring through the Acumen IQ finger cuff.
Beyond simply predicting an event, the Acumen HPI software provides a ‘Relationship View’ screen that offers insights into the potential underlying causes of hypotension, visually arranging hemodynamic parameters by preload, afterload, and contractility. This feature, combined with ‘Smart Alerts’ and ‘Smart Trend’ screens, supports clinicians in making proactive, goal-directed therapeutic decisions to address hemodynamic instability and potentially reduce the incidence, duration, and severity of intraoperative hypotension.
Clinical studies have demonstrated that the use of Acumen HPI software can significantly reduce the duration of intraoperative hypotension and is associated with improved patient outcomes, including a reduced risk of complications such as acute kidney injury and myocardial injury.

What Physicians Need to Know
The Acumen HPI software serves as an adjunctive predictive tool, offering early warning of impending hypotension and insights into its potential hemodynamic causes (preload, afterload, contractility). Clinicians should use the HPI parameter as additional quantitative information and always integrate it with a comprehensive review of the patient's complete hemodynamic state before making therapeutic decisions. The Mean Arterial Pressure (MAP) target for hypotension is adjustable, allowing for personalized care. Proactive intervention guided by HPI can lead to reduced duration and severity of hypotensive events.
The Acumen HPI software is part of the Acumen intelligent decision support suite and operates on the Edwards HemoSphere advanced monitoring platform. It requires either the Acumen IQ sensor (for invasive arterial line monitoring) or the Acumen IQ cuff (for non-invasive continuous blood pressure monitoring). The Critical Care product group, including Acumen HPI, is now part of BD (Becton, Dickinson and Company), with Edwards Lifesciences remaining the manufacturer of the products.

What the Web Says
The Acumen Hypotension Prediction Index (HPI) Feature Software is a predictive monitoring tool designed to alert clinicians to potential hypotensive events before they occur in surgical and non-surgical patients. It uses machine-learning algorithms to analyze cardiovascular vital signs and arterial waveforms, providing a score (0-100) indicating the likelihood of hypotension. The software aims to improve patient care by enabling proactive intervention and reducing the incidence, duration, and severity of intraoperative hypotension.
Overall: PositiveStrengths
- Predicts hypotensive events up to 15 minutes before they occur, allowing for proactive intervention.
- Significantly reduces the incidence, duration, and severity of intraoperative hypotension.
- Provides intelligent decision support by offering insights into the root cause of hypotension through a secondary screen displaying hemodynamic parameters.
- Demonstrates superior predictive abilities compared to traditional hemodynamic parameters like cardiac output and mean arterial pressure.
- Can be used with both invasive (arterial line) and non-invasive (Acumen IQ cuff) monitoring solutions.
- Supported by multiple clinical studies and randomized controlled trials showing its effectiveness.
Limitations
- Requires an arterial line for optimal use and is only compatible with Edwards' minimally invasive hemodynamic monitoring solutions.
- The HPI parameter should not be the sole basis for therapeutic decisions; a review of patient hemodynamics is recommended.
- Limited evidence on patient outcomes and for use in intensive care patients.
- No published evidence to support claims of cost savings from reduced adverse outcomes or length of stay.
- One retrospective study in major aortic surgery did not find a statistically significant reduction in hypotension burden, though clinically relevant trends were observed.
- May be associated with significantly more time with elevated Mean Arterial Pressure (MAP) in some cases.
