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)

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.

Intraoperative hypotension (IOH):

Though intraoperative hypotension is common in surgical patients, numerous studies now indicate that it is strongly associated with risk. Research is pointing to a strong association between intraoperative hypotension and increased risk of myocardial injury (MI) and acute kidney injury (AKI) in non-cardiac surgical patients.

88% of patients continuously monitored with an arterial line still experienced hypotension, defined as MAP <65 mmHg for
1 minute.2

IOH has elevated risks

Prolonged exposures below MAP thresholds of 65 mmHg are associated with increased risk of mortality, MI, and AKI after non-cardiac surgery.3,4

IOH is avoidable

Acumen HPI software combined with a treatment protocol achieved statistically significant reduction in IOH vs. standard of care.5,6

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.7

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.

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

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