Offers noninvasive

Accurately measures continuous blood pressure and hemodynamic parameters for patients who don't need, or can't have, an arterial line.1

Enables individualised
patient care

An advanced hemodynamic monitoring solution that helps guide individualised 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 optimise 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)

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.

Acumen IQ cuff and Acumen HPI software

Managing volume

Dynamic and flow-based parameters are more informative than conventional parameters in determining fluid responsiveness and may help guide individualised volume administration in patients and avoid excessive or insufficient administration.2

Continuous access to pressure and flow parameters allows you to evaluate hemodynamic instability and guide appropriate treatment. When managing perfusion, stroke volume can be optimised using the patient’s own Frank-Starling curve.

Frank-Starling relationship between preload and stroke volume (SV)

Avoidance of hypotension and strategies to optimise fluid management in surgical patients are two modifiable factors that may contribute to improved patient outcomes.
