Unlocks Acumen HPI software
Acumen IQ sensor unlocks this first-of-its-kind technology designed to help predict future hypotensive events.*
Acumen IQ sensor
Minimally-invasive predictive decision support
Acumen IQ sensor unlocks the ability to predict hypotensive events* and provides insight into the root cause of hypotension (preload, afterload, and /or contractility) with Acumen Hypotension Prediction Index (HPI) software. This next generation sensor is built on the foundation of the Edwards Lifesciences FloTrac sensor.
Attaches to any radial line
Acumen IQ sensor attaches to any existing radial arterial line and automatically calculates key parameters every 20 seconds.
Enables individualized patient care
Acumen IQ sensor is part of an advanced hemodynamic family of solutions that help guide individualized treatment decisions.
*A hypotensive event is defined as MAP <65 mmHg for a duration of at least one minute.
Features of Acumen IQ sensor
Acumen IQ sensor is available on the HemoSphere advanced monitoring platform. This sensor unlocks Acumen HPI software and enables you to proactively optimize perfusion using continuous blood pressure and advanced hemodynamic parameters. This first-of-its-kind predictive decision support software detects the likelihood of a patient trending towards a hypotensive event* before the event occurs, and provides you with insights to understand the root cause and inform a potential course of action for your patient.
Acumen IQ sensor attaches to any existing radial arterial line and automatically calculates key parameters every 20 seconds, reflecting rapid physiologic changes in surgical and nonsurgical patients in intensive care settings.

Clinical application
Manage perfusion
Maintaining necessary peripheral perfusion requires adequate peripheral blood pressure and adequate cardiac output. Acumen IQ sensor offers advanced hemodynamic parameters and continuous blood pressure to help you monitor perfusion, and access to the Acumen HPI software which provides you insight to determine the root cause of instability.
Risk of hypotension
Research findings have revealed strong association between intraoperative hypotension (IOH) and elevated risk of both acute kidney injury (AKI) and myocardial injury after noncardiac surgery (MINS).2,4,5
Acumen HPI software is effective in detecting hemodynamic instability and substantially reducing the amount of intraoperative hypotension when used in surgical patients who require intraoperative hemodynamic monitoring during noncardiac surgery.1
IOH is common2,3
88% of patients continuously monitored with an arterial line still experienced hypotension, defined as MAP <65 mmHg, for at least 1 min.4
IOH has elevated risks
Prolonged exposures below mean arterial pressure (MAP) thresholds of 65 mmHg are associated with increased risk of mortality, myocardial injury, and AKI after noncardiac surgery.2,5
IOH can be reduced
Acumen HPI software has demonstrated a reduction* in the duration of IOH by 57%.1
* Single arm, multicenter, prospective-to-historical control where patients received arterial line monitoring.
Manage volume
Dynamic and flow-based parameters are more informative than conventional parameters in determining fluid responsiveness and may help guide individualized volume administration in patients and avoid excessive or insufficient administration.
Continuous access to pressure and flow parameters allows you to evaluate hemodynamic instability and guide appropriate treatment. When managing perfusion, stroke volume can be optimized using the patient’s own Frank-Starling curve.
Acumen intelligent decision support suite
The Acumen intelligent decision support suite offers predictive decision support for the management of a hypotension.
Acumen HPI software
Acumen HPI software provides you with information regarding the likelihood of a patient trending towards a hypotensive event, and provides you with insights to understand the root cause and inform a potential course of action.
Acumen Analytics software
Acumen Analytics software enables you to retrospectively view and analyze hemodynamic parameters, including mean arterial pressure, providing you insights into the frequency, duration and prevalence of intraoperative hypotension in your practice.
