Acumen Assisted Fluid Management (AFM) Software Feature
Overview
The Acumen Assisted Fluid Management (AFM) Software Feature by Edwards Lifesciences is an advanced AI-enhanced tool designed to optimize fluid administration in surgical patients. It utilizes a sophisticated rules-based algorithm and machine learning to provide individualized fluid recommendations.
Integrated with the Acumen IQ sensor and displayed on the HemoSphere monitor, Acumen AFM software predicts a patient’s fluid responsiveness by analyzing their hemodynamic data and past responses to fluid administration. This predictive decision support helps clinicians keep patients within an optimal fluid range, adapting throughout a procedure by learning from the patient’s response to each analyzed fluid bolus.
The software automatically tracks volume administration and flow rate in real time, offering suggestions regarding the patient’s physiological condition and estimated response to fluid therapy. It is intended to simplify the implementation of fluid management protocols and perioperative goal-directed therapy (PGDT), aiming to reduce complications associated with both insufficient and excessive volume administration.
Acumen AFM is part of the broader Acumen intelligent decision support suite, which also includes tools for hypotension prediction and retrospective data analysis.

What Physicians Need to Know
Acumen AFM software serves as an adjunctive decision support tool; always integrate its recommendations with comprehensive patient assessment and other clinical data. While the software provides individualized fluid bolus suggestions and tracks administration, the ultimate decision for fluid management remains with the clinician. Pay attention to the user-defined fluid strategies and surgical approach settings to ensure the algorithm aligns with your clinical goals. Utilize the available clinical education and 24/7 technical support for optimal implementation and ongoing use.
The Acumen AFM software is an integral part of the Edwards Lifesciences (now BD Critical Care) Acumen suite, requiring the Acumen IQ sensor and HemoSphere monitor for full functionality. The Acumen IQ sensor connects to existing radial arterial lines, providing continuous hemodynamic data. The system also integrates with Acumen Analytics software for retrospective data review, allowing for a comprehensive understanding of patient hemodynamics across various monitoring platforms.

What the Web Says
The Acumen Assisted Fluid Management (AFM) Software Feature by Edwards Lifesciences is a real-time clinical decision support tool that uses machine learning to provide individualized fluid recommendations for surgical patients aged 18 and above who require advanced hemodynamic monitoring. It analyzes cardiovascular vital signs and past responses to fluid boluses to predict a patient's estimated response to fluid therapy, aiming to optimize fluid administration and potentially reduce risks of fluid overload or inappropriate treatment. The system operates as an adjunctive, open-loop tool, meaning clinicians make the final therapeutic decisions based on the software's suggestions and other patient information.
Overall: PositiveStrengths
- Provides individualized fluid recommendations based on machine learning and patient's past responses.
- Assists clinicians in optimizing fluid administration, potentially reducing risks of fluid overload or inappropriate treatment.
- Demonstrated to improve fluid responsiveness and increase stroke volume more effectively than conventional clinician-guided methods.
- Automatically tracks volume administration and flow rate in real-time.
- Can lead to patients spending more time in a preload-independent state during surgery.
- May lead to lower arterial lactate at the end of major liver surgery compared to more restrictive fluid strategies.
Limitations
- The device does not independently direct therapy; clinicians must review and make final decisions.
- Requires integration with compatible sensors, specifically the Acumen IQ sensor.
- Clinical studies have noted a high rate of declined/discarded suggestions (approximately 50%).
- The effectiveness relies on how clinicians interpret and integrate recommendations into practice, with a potential learning curve.
- Limited data available on how AFM is adopted in routine clinical practice and how clinician interaction evolves over time.
- No specific reviews or opinions from healthcare IT, tech reviewers, Reddit, G2, or Capterra were found for this specific software feature, though general Acumen software is listed on Capterra.
