Medical staff reviewing monitors

Stay ahead of critical moments

In the OR, every second counts. And as an anesthesiologist or anesthesia assistant, patient safety is your number-one priority. Today you are faced with an increasingly complex patient population. HemoSphere advanced monitoring platform provides a comprehensive view of tissue oximetry and hemodynamics, giving you confidence in knowing continuous oxygen saturation and perfusion.

For more than 50 years, Edwards Lifesciences has been helping you make proactive clinical decisions and advance the care of surgical and acutely ill patients across the continuum of care.

Hypotension management

Intraoperative hypotension matters. Recent studies show associations between intraoperative hypotension and increased risk of acute kidney injury (AKI) and myocardial injury1-3 — the leading cause of post-operative mortality within 30 days after surgery.1 Prolonged exposures below mean arterial pressure (MAP) thresholds of 65 mmHg are associated with an increased risk of myocardial injury and AKI after noncardiac surgery.1

Acumen Hypotension Prediction Index (HPI) software, Acumen IQ sensor

Acumen Hypotension Prediction Index (HPI) software

Developed in partnership with clinicians, our 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.

Studies have shown that Acumen HPI software:

  • Achieves statistically significant reduction of hypotension when combined with a treatment protocol in noncardiac surgery vs. standard of care4,5
  • Demonstrates superior predictive abilities for hypotension than common hemodynamic parameters such as cardiac output (CO), stroke volume (SV), and changes in mean arterial pressure (MAP)6
  • Has proven and reliable accuracy7

Acumen IQ sensor

The Acumen IQ sensor connects to any existing radial arterial line and unlocks the ability to predict the likelihood of a patient trending towards a hypotensive event* before the event occurs with the Acumen HPI software. In addition, the Acumen IQ sensor automatically updates advanced hemodynamic parameters every 20 seconds, reflecting rapid physiological changes in moderate- to high-risk surgery. Advanced hemodynamic parameters provided by the Acumen IQ sensor offer you continuous insight into your patient’s hemodynamic status.

*A hypotensive event is defined as mean arterial pressure (MAP) <65 mmHg for at least one minute.
Perfusion optimization

Advanced hemodynamic monitoring provides access to continuous pressure and flow parameters, giving you valuable insight into the adequacy of perfusion. Dynamic parameters can help identify the most appropriate therapy, such as helping to decide between volume administration or the administration of vasopressors or inotropes.

ClearSight cuff, FloTrac sensor, VolumeView sensor, Swan-Ganz pulmonary artery catheter

ClearSight system

The ClearSight finger cuff provides advanced hemodynamic parameters and continuous noninvasive blood pressure (BP) monitoring. The noninvasive ClearSight system allows continuous assessment of your patients' physiological needs, enabling you to evaluate hemodynamic instability and guide appropriate treatment.
