Unlocks Acumen HPI software
Acumen IQ cuff unlocks the first-of-its-kind technology designed to help predict future hypotensive events*.
*A hypotensive event is defined as MAP <65 mmHg for a duration of at least one minute.
Acumen IQ cuff
Smart, noninvasive hemodynamic monitoring
This first-of-its-kind noninvasive solution unlocks Acumen Hypotension Prediction Index (HPI) software. It also provides continuous blood pressure measurements and advanced hemodynamic parameters, giving you insight to your patients' hemodynamic status.
Offers noninvasive monitoring
Accurately measures continuous blood pressure and hemodynamic parameters for patients who don't need, or can't have, an arterial line.1
Enables individualized patient care
An advanced hemodynamic monitoring solution that helps guide individualized treatment decisions.
Features of Acumen IQ cuff
Acumen IQ cuff is available on the HemoSphere advanced monitoring platform. This noninvasive finger cuff unlocks Acumen HPI software and enables you to proactively optimize perfusion using continuous blood pressure and advanced hemodynamic parameters. The finger cuff provides automatically calculated, beat-to-beat hemodynamic information and offers you access to advanced hemodynamic parameters for patients who don’t need, or can’t have, an arterial line.
Advanced hemodynamic parameters
- Hypotension prediction index (HPI)
- Maximum slope of the arterial pressure upstroke (dP/dt)
- Dynamic arterial elastance (Eadyn)
- Stroke volume (SV)
- Stroke volume variation (SVV)
- Mean arterial pressure (MAP)
- Cardiac index (CI)
- Systemic vascular resistance (SVR)
| Model numbers | Description | Unit of Measure |
| AIQCS | Acumen IQ cuff - small | EA |
| AIQCM | Acumen IQ cuff - medium | EA |
| AIQCL | Acumen IQ cuff - large | EA |
The easy application and snug fit of the Acumen IQ finger cuff self-coiling design eliminates placement errors on a patient to improve consistency.
Clinical application
Manage perfusion, noninvasively
Maintaining necessary peripheral perfusion requires adequate peripheral blood pressure and adequate cardiac output. Acumen IQ cuff offers advanced hemodynamic parameters and continuous blood pressure to help you monitor perfusion, and access to the Acumen HPI software provides you insight to determine the root cause of instability.
Risk of hypotension
Research findings have revealed strong associations between intraoperative hypotension (IOH) and elevated risk of both acute kidney injury (AKI) and myocardial injury after noncardiac surgery (MINS).2,3,4
Acumen HPI software is effective in detecting hemodynamic instability and substantially reducing the amount of intraoperative hypotension when used in surgical patients who require hemodynamic monitoring during noncardiac surgery.
IOH is common6
88% of patients continuously monitored with an arterial line still experienced hypotension, defined as MAP <65 mmHg for 1 minute.5
IOH has elevated risks
Prolonged exposures below MAP thresholds of 65 mmHg are associated with increased risk of mortality, myocardial injury and AKI after noncardiac surgery.2,6
IOH can be reduced
Acumen HPI software has demonstrated a reduction* in the duration of IOH by 57%.7
* Single arm, multicenter, prospective-to-historical control where patients received arterial line monitoring.
Managing 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.8
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.
Avoidance of hypotension and strategies to optimize fluid management in surgical patients are two modifiable factors that may contribute to improved patient outcomes.
