BP_DIASTOLIC | mmHg | 30 seconds | 30 to 120 | 👤1 |
Definition
BP_DIASTOLIC is the DeepAffex Cloud's estimate of the subject's Diastolic
Blood Pressure. It is based on analyzing facial blood-flow data (TOI).
It estimates diastolic blood pressures as high as 120 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
Diastolic blood pressure is the amount of pressure in subject's brachial arteries when their heart muscle is relaxed, measured in millimetres of mercury (mmHg).
Diastolic 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:
| Diastolic Blood Pressure (mmHg) | |
|---|---|
| Normal | < 80 |
| Hypertension | ≥ 80 |
Diastolic blood pressure levels elsewhere
According to the European Society of Cardiology and the European Society of Hypertension, high blood pressure (hypertension) is defined as the following:
| Diastolic Blood Pressure (mmHg) | |
|---|---|
| Optimal | < 80 |
| Normal | 80–84 |
| High Normal | 85–89 |
| Hypertension | ≥ 90 |
