Acumen Analytics software offers you retrospective data analysis and hemodynamic insights into patient perfusion all on your personal computer.

Acumen Analytics software allows you to retrospectively view and analyze monitored hemodynamic parameters from the EV1000 clinical platform and/or HemoSphere advanced monitoring platform when used with Acumen IQ cuff, Acumen IQ sensor, ClearSight finger cuff, FloTrac sensor, ForeSight sensor, or TruWave disposable pressure transducer.

When using any of the blood pressure monitoring cuffs and sensors (Acumen IQ cuff, Acumen IQ sensor, ClearSight finger cuff, FloTrac sensor, or TruWave disposable pressure transducer), Acumen Analytics software allows you to highlight key events including:

Hypotension frequency

Hypotension frequency

Hypotension duration

Key features of Acumen Analytics software

Main viewing pane

Customizable viewing pane

With a streamlined and customizable tile layout, the main viewing page organizes a list of all cases, cohort summaries, and cohort comparison for convenient overviews.

Hypotension Statistics

Hypotension statistics

This case summary list provides statistics on key hypotensive calculations such as average number of hypotensive events*, duration of each event, number of patients in a cohort that experienced hypotension.

Cohort comparison

Cohort comparison

The cohort comparison screen allows you to retrospectively compare data from two cohorts. Hypotension data includes duration of hypotension and mean arterial pressure (MAP) events. The customizable cohort summary screen displays a summary of the data collected for the chosen patient or patient group.

Trend parameters

Trend parameters

At the core of Acumen Analytics software is advanced hemodynamic parameter data. You can review recorded data on a number of valuable pressure and flow parameters as well as tissue oxygen saturation from the EV1000 and HemoSphere monitoring platforms. See chart below for available parameters.

Parameter**Description
Hypotension Prediction Index (HPI) Indicates the likelihood of a patient trending towards a hypotensive event*
Dynamic arterial elastance (Eadyn) Ratio of pulse pressure variation (PPV) to stroke volume variation (SVV). It's an estimate of arterial elastance.
Systolic slope (dP/dt) Maximum upslope of the arterial pressure waveform from a peripheral artery. It is the maximum rate of the arterial pressure rise during left ventricular contraction
Cardiac output (CO) Volume of blood pumped by the heart measured in liters per minute
Cardiac index (CI) Cardiac output relative to body surface area (BSA)
Systolic pressure (SYS) Systolic blood pressure
Diastolic pressure (DIA) Diastolic blood pressure
Mean arterial pressure (MAP) Averaged systemic blood pressure over one cardiac cycle
Pulse rate (PR) Number of ventricular contractions per minute
Stroke volume (SV) Volume of blood pumped with each heart beat
Stroke volume index (SVI) Stroke volume relative to body surface area (BSA)
Systemic vascular resistance (SVR) The resistance that the left ventricle must overcome to eject stroke volume with each beat
Systemic vascular resistance index (SVRI) SVR relative to body surface area
Stroke volume variation (SVV) The percent difference between SVmin, max and mean
Central venous oximetry (ScvO2) Venous oxygen saturation as measured in the superior vena cava
Mixed venous oximetry (SvO2) Venous oxygen saturation as measured in the pulmonary artery
Tissue oxygen saturation (StO2) A noninvasive continuous assessment of the balance between oxygen delivery and consumption through either cerebral or somatic tissue oximetry
*A hypotensive event is defined as MAP <65 mmHg for a duration of at least one minute.
**Not all parameters are available with all sensors or all monitoring platforms
Risk of hypotension

Research findings have revealed strong associations between intraoperative hypotension (IOH) and elevated risk of both acute kidney injury (AKI) and myocardial injury after noncardiac surgery (MINS).1,2,3

Acumen HPI software is effective in detecting hemodynamic instability and substantially reducing the amount of intraoperative hypotension when used in surgical patients who require intraoperative hemodynamic monitoring during noncardiac surgery.

IOH is
common1

88% of patients continuously monitored with an arterial line still experienced hypotension, defined as MAP <65 mmHg for at least 1 min.4

stat-icon

IOH has
elevated risks

Prolonged exposures below mean arterial pressure (MAP) thresholds of 65 mmHg are associated with increased risk of mortality, myocardial injury and AKI after noncardiac surgery.1,5

IOH can
be reduced

Acumen HPI software has demonstrated a reduction* in the duration of IOH by 57%.6

Single arm, multicenter, prospective-to-historical control where patients received arterial line monitoring.
Physiology of perfusion

Adequate perfusion requires adequate arterial pressure and cardiac output (CO)

Adequate perfusion requires adequate arterial pressure and cardiac output (CO)

Cardiac Output (CO) = Stroke Volume x Heart Rate

Cardiac Output (CO) = Stroke Volume x Heart Rate

Preload: the tension of myocardial fibers at the end of diastole, as a result of volume in the ventricle

Preload: the tension of myocardial fibers at the end of diastole, as a result of volume in the ventricle

Stroke Volume (SV): volume of blood pumped from the left ventricle per heartbeat

Stroke Volume (SV): volume of blood pumped from the left ventricle per heartbeat

When managing volume, stroke volume variation (SVV) has been proven to be a highly sensitive, reliable, and specific indicator for preload responsiveness in loading conditions induced by mechanical ventilation.7-10

Acumen Intelligent Decision Support Suite
Acumen IQ cuff and Acumen HPI software

Acumen Hypotension Prediction Index (HPI) software

Acumen HPI software provides you with information regarding the likelihood of a patient trending toward a hypotensive event.*

A single arm, multicenter study demonstrated that Acumen HPI software reduced hypotension by 57% compared to a historical control where patients received arterial line monitoring. This predictive software was shown to detect hemodynamic instability and substantially reduced intraoperative hypotension when used in surgical patients who require hemodynamic monitoring during noncardiac surgery.

*A hypotensive event is defined as MAP <65 mmHg for a duration of at least one minute.
