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 sensor, FloTrac sensor, ForeSight Elite sensor, ClearSight finger cuff, or TruWave disposable pressure transducer.
When using any of the blood pressure monitoring sensors (Acumen IQ sensor, FloTrac sensor, ClearSight finger cuff, or TruWave disposable pressure transducer), Acumen Analytics software allows you to highlight key events including:
How Acumen Analytics software works
Acumen Analytics software reviews retrospective hemodynamic parameter data from the EV1000 clinical platform and/or HemoSphere advanced monitoring platform when used with an Acumen IQ sensor, FloTrac sensor, ForeSight Elite sensor, ClearSight finger cuff, 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.
Main 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 a hypotensive event.
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 under 65 mmHg. 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. 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) and a measure of arterial tone|
|Systolic slope (dP/dt)||Maximum upslope of the arterial pressure waveform from a peripheral artery. It measures the maximum rate of the arterial pressure rise during left ventricular contraction|
|Cardiac output (CO)||Continuous measurement of the 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|
Intraoperative hypotension is common.
In noncardiac surgery patients, research findings have revealed strong associations between intraoperative hypotension and elevated risk of both acute kidney injury (AKI) and myocardial injury after noncardiac surgery (MINS).1,2,3
MINS — the most common cardiovascular complication that occurs after noncardiac surgery — is the leading cause of mortality within one month following surgery.1,4
More than 1 in 12 patients (8 million people globally) over 45 years old experience MINS each year after non-cardiac surgery.4,5,6
- Once a patient's mean arterial pressure (MAP) drops below 65 mmHg, it takes just 10 minutes of exposure to see higher associations between intraoperative hypotension and MINS.1
- Once a patient's MAP drops below 50 mmHg, it takes only one minute for the risk of MINS and AKI to increase significantly, making early identification of a hypotensive event critical.1
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 and specific indicator for preload responsiveness. SVV has also been shown to be an accurate predictor of fluid responsiveness in loading conditions induced by mechanical ventilation.7-10
Hypotension Prediction Index
This first-of-its-kind predictive decision support software detects the likelihood of 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.
The Acumen IQ sensor
The Acumen IQ sensor — part of the minimally-invasive family of hemodynamic sensors — unlocks the Acumen Hypotension Prediction Index software. The Acumen IQ system* automatically updates advanced parameters every 20 seconds, reflecting rapid physiological changes in moderate- to high-risk surgery.
