Decoding the signals of our Blood Pressure

Discover how Aktiia merges vast health datasets with AI, pioneering predictive care and proactive health management strategies.

Aktiia’s Approach to Pulse Wave Analysis

Aktiia’s Optical Blood Pressure Monitoring (OBPM®) technology analyses photoplethysmographic (PPG) signals acquired at your wrist to estimate blood pressure, with no pain or inflation.

01

PPG Sensor

The aktiia bracelet shines a green light to analyse how the arteries below the skin surface pulsate. This is the same sensing principle as most other optical heart rate monitors at the wrist

02

Optical Signal

Aktiia goes beyond a heart rate monitor: instaid of counting pulses, we examine their shape

03

OBPM Algorithm

The pulse shape of your skin arteries contains information on your actual blood pressure.

04

Blood Pressure

Unfortunately, this information is obscured by noise.
After 15 years of research and validation, Aktiia is able to extract this information to provide you with accurate blood pressure values around the clock.

Validated Accuracy

Our pivotal study has proven that the Aktiia solution is as accurate as accepted reference measurements.

Tracking BP Changes in Anesthetised Patients

“As the principal investigator of Aktiia’s pivotal clinical trial, I am pleased that the result of our study shows that Aktiia solution is accurate and allows patients and physicians to track their blood pressure daily. I believe Aktiia solution has the potential to change the management of hypertension.”

At the top of the screen, you will see the 24 hour average of your blood pressure values. This is a quick overview of your BP and encourages you to read further.
2
The colour-coded graph shows you how your blood pressure varied during the day and night.
3
The Trends card lets you know whether you should be worried about any red spikes or if they are isolated measurements that aren’t a cause for concern.
4
This is your resting heart rate value, averaged over 24 hours. Any number between 60 and 100 is considered as good.

Why Does 24/7 Blood Pressure Matter?

Decades of clinical research support the importance of:
  • More frequent, accurate blood pressure measurements at home
  • Measurement of nighttime blood pressure to assess cardiovascular risk
  • Adjustment of medication titration based on blood pressure changes
  • The impact of lifestyle changes like diet, exercise, or meditation on blood pressure control.
