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:
How Acumen Analytics software works
Acumen Analytics software analyzes retrospective hemodynamic parameter data from the EV1000 clinical platform and/or HemoSphere advanced monitoring platform when used with an Acumen IQ cuff, Acumen IQ sensor, ClearSight finger cuff, FloTrac sensor, ForeSight sensor, or TruWave disposable pressure transducer.
Please note that not all sensors may be used with all monitoring platforms.
Monitoring sessions can be downloaded from the HemoSphere advanced monitoring platform or EV1000 clinical platform onto the Acumen Analytics software onto your desktop or laptop computer. The report includes demographics data that you can organize and analyze. Patient identifiers are omitted from the data.
The Acumen Analytics software primary screen allows you to retrospectively analyze data within and between cohorts or on individual patients.
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.
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.
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.
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.
|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|
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.
88% of patients continuously monitored with an arterial line still experienced hypotension, defined as MAP <65 mmHg for at least 1 min.4
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
Acumen HPI software has demonstrated a reduction* in the duration of IOH by 57%.6
Adequate perfusion requires adequate arterial pressure and cardiac output (CO)
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
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 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.
Acumen IQ sensor
The Acumen IQ sensor unlocks Acumen HPI software for surgical and nonsurgical patients. The Acumen IQ sensor automatically updates advanced parameters every 20 seconds, reflecting rapid physiological changes in moderate- to high-risk surgery and patients in the intensive care settings.
Acumen Analytics software
Acumen Analytics software enables you to retrospectively view and analyze hemodynamic parameters, including mean arterial pressure, providing you insights into the frequency, duration and prevalence of intraoperative hypotension in your practice.
HemoSphere advanced monitoring platform
The only modular hemodynamic monitoring platform to offer full-range cuff, sensor and catheter compatibility and first-of-its-kind predictive decision support software, HemoSphere advanced monitoring platform enables proactive, individualized patient management.
