As the case progresses, the software automates a protocolized fluid management approach, allowing for individualized fluid recommendation

Fluid optimization

Large patient-to-patient variability in fluid administration exists between clinicians and within surgical procedures.1–3

Standardized fluid optimization matters
This lack of a standardized approach leads to case-by-case variations in outcomes. Too much or too little fluid administration can lead to complications including mortality, acute kidney injury (AKI) and gastrointenstinal and respiratory problems – as well as increased length of stay, which leads to higher hospital costs.1-4

Perioperative goal-directed therapy (PGDT)
Implementing PGDT protocols in moderate- to high-risk surgery has shown significant clinical and economic benefits, including a reduction in morbidity and length of hospital stay.5-7

Key features of Acumen AFM software

Acumen AFM software supports you in implementing your desired fluid management protocol.

Predictive decision support

Acumen AFM software uses a rule-based machine learning algorithm to make fluid management suggestions and predict a patient’s fluid responsiveness based on hemodynamic data and past fluid responsiveness. Recommendations appear on the Acumen AFM software dashboard of HemoSphere monitor, where you can accept (or decline) the recommendation and administer a fluid bolus upon review of the patient’s complete hemodynamic state.

Fluid Bolis

Individualized fluid administration

Acumen AFM software adapts and recommends patient-specific fluid administration as the algorithm analyzes boluses. Throughout a surgical procedure, Acumen AFM software learns from the patient’s response to each analyzed fluid bolus to refine its future recommendations.

Acumen IQ sensor unlocks Acumen Hypotension Prediction Index (HPI) and Acumen AFM software. The sensor connects to any existing radial arterial line and offers you continuous insights into your patients’ hemodynamic status.

Acumen Hypotension Prediction Index (HPI) software

Acumen HPI software is effective in detecting hemodynamic instability and substantially reducing the duration of intraoperative hypotension when used in surgical patients who require hemodynamic monitoring during non-cardiac surgery.*

A recent study demonstrated a 57% reduction* in duration of intraoperative hypotension.8
