Acumen Analytics software offers you retrospective data analysis and haemodynamic insights into patient perfusion, all on your personal computer.
Acumen Analytics software allows you to retrospectively view and analyse monitored haemodynamic parameters from the HemoSphere advanced monitoring platform when used with Acumen IQ cuff, Acumen IQ sensor, ClearSight finger cuff, FloTrac sensor, or ForeSight sensor.
When using any of the blood pressure monitoring cuffs and sensors (Acumen IQ cuff, Acumen IQ sensor, ClearSight finger cuff, or FloTrac sensor), Acumen Analytics software allows you to highlight key events including:
How Acumen Analytics software works
Acumen Analytics software analyses retrospective haemodynamic parameter data from the HemoSphere advanced monitoring platform when used with an Acumen IQ cuff, Acumen IQ sensor, ClearSight finger cuff, FloTrac sensor or ForeSight sensor.
Monitoring sessions can be downloaded from the HemoSphere advanced monitoring platform onto the Acumen Analytics software on your desktop or laptop computer. The report includes demographics data that you can organise and analyse. Patient identifiers are omitted from the data.
The Acumen Analytics software primary screen allows you to retrospectively analyse data within and between cohorts or for individual patients.
Customisable viewing pane
With a streamlined and customisable tile layout, the main viewing page organises 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 customisable 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 haemodynamic parameter data. You can review recorded data on a number of valuable pressure and flow parameters as well as tissue oxygen saturation from the HemoSphere monitoring platform. 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 litres 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|
Numerous studies show IOH is strongly associated with risk, especially myocardial injury, acute kidney injury, and mortality.1-8
Acumen HPI software is effective in detecting haemodynamic instability and substantially reducing the amount of intraoperative hypotension when used in surgical patients who require intraoperative haemodynamic monitoring during non-cardiac surgery.15
88% of non-cardiac surgery patients (19,446/22,109) monitored with an arterial line experienced at least one hypotensive event* for at least 1 minute.^11
A wealth of evidence suggests a link between IOH and the increased risk of adverse outcomes – including MI, AKI, and mortality – after non-cardiac surgery.1,2,11
Acumen HPI software has demonstrated a reduction in the duration of IOH by 57%.15
*Hypotension/hypotensive event was defined as MAP <65 mmHg for at least one minute.11
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.9-12
Acumen Hypotension Prediction Index (HPI) software
Acumen Hypotension Prediction Index software is the first predictive technology that provides you with information regarding the likelihood of a patient trending toward a hypotensive event*.12-14
Acumen IQ cuff
Acumen IQ cuff enables you to unlock the Acumen Hypotension Prediction Index (HPI) software for surgical patients, while delivering continuous blood pressure monitoring and advanced haemodynamic parameters noninvasively.
Acumen IQ sensor
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 analyse haemodynamic parameters, including mean arterial pressure, providing you insights into the frequency, duration and prevalence of intraoperative hypotension in your practice.
