Systolic Blood Pressure

Definition

BP_SYSTOLIC is the DeepAffex Cloud's estimate of the subject's Systolic Blood Pressure. It is based on analyzing facial blood-flow data (TOI). It estimates systolic blood pressures as high as 180 mmHg.

Accuracy of blood pressure estimates

In a study published in the American Heart Association journal, Circulation: Cardiovascular Imaging (Vol. 12, No. 8) the proprietary technique used by Anura called Transdermal Optical Imaging (TOI) has been shown to measure blood pressure with an average overall accuracy of 95% over the following ranges:

• Systolic: 100–139 mmHg
• Diastolic: 60–89 mmHg

Background

Systolic blood pressure is the peak pressure in subject's brachial arteries during the contraction of their heart muscle, measured in millimetres of mercury (mmHg).

Systolic blood pressure levels in the USA

According to the American Heart Association and the American College of Cardiology, high blood pressure (hypertension) is defined as the following:
