The Acumen Hypotension Prediction Index software enables clinicians to detect and address potentially developing hypotensive events* before they occur.
Research demonstrates a strong correlation between both increased acute kidney injury (AKI) and myocardial injury after noncardiac surgery (MINS) in patients that experience intraoperative hypotension. Noncardiac surgery patients with prolonged exposure below a mean arterial pressure (MAP) of 65 mmHg were those at risk. Studies also demonstrate patients that experience a low MAP are at increased risk of 30-day mortality post noncardiac surgery.1 How can you manage hypotensive events for your patients?
The Acumen Hypotension Prediction Index software provides you with insights to detect and inform a potential course of action when a patient is trending towards a hypotensive event*, before the event occurs.
Part of the Acumen decision support suite, the Acumen Hypotension Prediction Index software is unlocked by the FloTrac IQ sensor.
Three elements of the Acumen Hypotension Prediction Index software
Hypotension Prediction Index (HPI) parameter
The HPI parameter indicates that a patient has a likelihood of experiencing a hypotensive event.* The proprietary algorithm - developed using data from almost 59,000 past hypotensive events* and over 144,000 non-hypotensive events** - coupled with machine learning techniques detects potential hypotensive trending of a patient's mean arterial pressure (MAP). The HPI value is updated every 20 seconds.
HPI high alert popup.
When the HPI parameter for a patient exceeds 85, an auditory alarm will sound. When the HPI parameter exceeds 85 for two consecutive readings, a high alert popup window will appear, prompting you to review the patient hemodynamics using the secondary screen.
HPI secondary screen.
The HPI secondary screen is easily accessed through the HPI high alert popup, by pressing the button on the HPI parameter globe, or at any time through the menu on your monitor. It visually displays advanced parameters on the screen which are arranged by preload, contractility and afterload and which provide you potential insight into the cause of a hypotensive event.

Uncovering the possible root cause and treatment paths.
Understanding the root cause of hypotension requires investigation of pressure and flow parameters.
- Stroke Volume Variation (SVV) – the percent difference between minimum and maximum SV during a respiratory cycle. Serves as an accurate marker of position status on the Frank-Starling curve.
- dP/dt – a sensitive measure of changes in the contractility of the left ventricle.
- Dynamic Arterial Elastance (Eadyn) – the ratio of pulse pressure variation to stroke volume variation (PPV/SVV).
The FloTrac IQ sensor unlocks the Hypotension Prediction Index software that is part of the Acumen decision support software suite. The FloTrac IQ sensor is part of the FloTrac family of hemodynamic sensors.
Individualized volume management with the added intelligence of the hypotension prediction index feature, the FloTrac IQ system automatically updates advanced parameters every 20 seconds. This reflects rapid physiological changes in moderate-to-high-risk surgery patients. Advanced hemodynamic parameters provided by the FloTrac IQ sensor offer you continuous insight to determine your patient's hemodynamic status. The minimally-invasive FloTrac IQ sensor connects to any existing radial arterial line.
