Incidence, duration, and severity of IOH* during noncardiac surgery were significantly reduced vs standard of care.3,4
Predict hypotension sooner. Act ahead of time1

Multiple studies have shown:
Acumen HPI software was highly accurate in predicting hypotension*.1,5
Acumen HPI software was highly accurate in identifying hemodynamic instabilities.6
Key elements of the Acumen HPI software
* A hypotensive event is defined as MAP <65 mmHg for a duration of at least one minute.
Clinical evidence
Reductions in incidence, duration, and severity of IOH3,4
Highlights from Wijnberge M, et al. 2020
From the HYPE trial, elective noncardiac surgery patients monitored with Acumen HPI software had a median duration of IOH per patient of 8 minutes compared to 32.7 minutes in a control group; p<0.001.3
Intervention (n=31), control (n=29)

Highlights from Schneck E, et al. 2020
Incidence of IOH (events per hour) in total hip arthroplasty patients monitored with Acumen HPI software was 0 events compared to 5 events in a prospective control and 2 events in a historical control; p<0.001.4
Intervention (n=25), prospective control (n=24), historical control (n=50)
Accurate prediction of IOH1,6
Highlights from Davies SJ, et al. 2020
Acumen HPI software had superior ability to predict IOH 5 and 10 minutes before an event vs. all other measured hemodynamic parameters.6
Highlights from Hatib F, et al. 2018
At 10 minutes before an event, Acumen HPI software predicted IOH with a specificity of 89%, a sensitivity of 90% and an AUC of 0.95.1
Acumen intelligent decision support suite
The Acumen intelligent decision support suite offers both predictive and retrospective decision support for the management of hypotension.

Acumen IQ cuff (noninvasive)
Acumen IQ cuff unlocks the Acumen HPI software while delivering continuous blood pressure monitoring and advanced hemodynamic parameters noninvasively.

Acumen IQ sensor (minimally-invasive)
Acumen IQ sensor unlocks the Acumen HPI software and automatically updates advanced parameters every 20 seconds, reflecting rapid physiological changes in patients.

HemoSphere advanced monitoring platform
The only modular hemodynamic monitoring platform to offer full-range cuff, sensor, and catheter compatibility. HemoSphere monitor enables proactive, individualised patient management.

Acumen Analytics software
Acumen Analytics software enables you to retrospectively view and analyse hemodynamic parameters, including mean arterial pressure, providing you insights into the frequency, duration and prevalence of intraoperative hypotension in your practice.

TopMedTalk podcasts on Intraoperative Hypotension (IOH)
The TopMedTalk podcast is a leading source of high value medical discussion and education in Anaesthesia, Perioperative Care and Enhanced Recovery. We've featured interviews with key opinion leaders, academics, medical practitioners and policy makers.
Listen below to podcasts on hypotension and Acumen Hypotension Prediction Index (HPI) software. You can also find these episodes of TopMedTalk through wherever you get your podcasts.
Avoiding the hypotension hazard
The Acumen Hypotension Prediction Index (HPI) software takes 2.6 million features from a single waveform which it then applies to 133 million different wave forms looking for factors which can predict hypotension. It's the first fully approved foray into predictive analytics for the world of anaesthesia.
This conversation looks at how it works and how it is being adopted in detail.
