Acumen analytics software
Acumen analytics software offers you retrospective data analysis and hemodynamic insights into patient perfusion.
Acumen analytics software allows clinicians to retrospectively view and analyze monitored hemodynamic parameters from the Acumen IQ sensor, FloTrac sensor, or ClearSight finger cuff, highlighting key events including:
How Acumen analytics software works
Acumen Analytics software reviews retrospective hemodynamic parameter data from the Acumen IQ sensor, FloTrac sensor, or ClearSight finger cuff.
Please note that not all sensors may be used with all monitoring platforms.
Monitoring sessions, including demographic data, can be downloaded from the HemoSphere advanced monitoring platform or EV1000 clinical platform into Acumen Analytics software for organization and analysis. Patient identifiers are omitted from the collection of data.
The Acumen Analytics software primary screen allows the user to retrospectively analyze data within and between cohorts or individual patients.
Main viewing pane
With a streamlined tile layout, the main viewing page organizes a list of all cases, cohort summaries, and cohort comparisons for convenient overviews.
This case summary lists statistics on hypotensive calculations such as average number of hypotensive events, duration of each event, and time-weighted average of hypotension for each patient.
The cohort comparison screen allows clinicians 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. Clinicians can review recorded data on a number of valuable pressure and flow parameters involved in clinical decision making. See chart below for available parameters.
|Cardiac output (CO)||Volume of blood pumped by the heart in liters per minute|
|Cardiac index (CI)||Cardiac output relative to body surface area (BSA)|
|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|
|Systolic pressure (SYS)||Systolic blood pressure|
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 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
Acumen Hypotension Prediction Index (HPI) software is a first-of-its-kind predictive decision support software detects the likelihood of a hypotensive event before it occurs. Additionally HPI provides insights into the root causes of the event and helps you identify the best potential course of action for your patient.
*A hypotensive event is defined as MAP <65 mmHg for a duration of at least one minute.
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.
Acumen analytics softwareAcumen Analytics is a software that provides clinicians with retrospective hemodynamic insights into patient perfusion when managing patients with pressure and flow parameters. Acumen Analytics software allows clinicians to view and analyze monitored hemodynamic parameters from the Acumen IQ sensor, FloTrac sensor, or ClearSight finger cuff, highlighting key events including hypotension duration, frequency, and severity.
