Blood Pressure
Blood pressure (BP) refers to the force exerted by circulating blood on the walls of the arteries. It is an essential health indicator used to assess cardiovascular health and the risk of conditions such as hypertension and heart disease. The IntelliProve Blood Pressure Biomarker estimates systolic and diastolic blood pressure values using a combination of rPPG-derived signals and user-reported inputs.
Maintaining a normal blood pressure level is crucial for overall health. A consistently elevated blood pressure (hypertension) increases the risk of heart disease, stroke, and kidney problems.
How is it calculated**?**
Section titled “How is it calculated**?**”The blood pressure biomarker is derived from a machine-learning model trained on a combination of rPPG signal features (extracted from the Face Scan) and user metadata. This model estimates both systolic and diastolic blood pressure in mmHg.
Accuracy
Section titled “Accuracy”IntelliProve continuously validates its blood pressure biomarker against clinically measured blood pressure values. Comparative studies with the golden standard are performed to assess the accuracy of rPPG-based estimations, ensuring alignment with medical standards.
Currently, the model’s performance is as follows:
- Systolic Blood Pressure: -3.82 ± 8.43 mmHg (Mean error ± Standard deviation)
- Diastolic Blood Pressure: -4.52 ± 14.61 mmHg (Mean error ± Standard deviation)
How can it be used?
Section titled “How can it be used?”Blood pressure is a critical measure of cardiovascular health. It can be used to:
- Monitor trends over time: Identify fluctuations in blood pressure that may indicate health risks.
- Support hypertension risk assessment: Combined with other IntelliProve health metrics, blood pressure insights can help estimate the risk of developing hypertension.
- Encourage lifestyle improvements: Elevated blood pressure can indicate stress, poor diet, or lack of exercise. Monitoring BP values can help users take preventive action.
IntelliProve’s blood pressure biomarker can be integrated into health platforms to provide users with real-time feedback on their cardiovascular health.
Interpreting results
Section titled “Interpreting results”Blood pressure is returned as two numerical values: systolic BP (higher value) and diastolic BP (lower value), both expressed in mmHg. The values can be requested via the Widget or the Rest API.
Definitions
Section titled “Definitions”| Name | Unit | Range | programmatic name | Health profile |
|---|---|---|---|---|
| Blood Pressure (Systolic) | mmHg | 95-160 | systolic_blood_pressure | Physical Health |
| Blood Pressure (Diastolic) | mmHg | 60-105 | diastolic_blood_pressure | Physical Health |
Values
Section titled “Values”| Value Systolic BP (mmHg) | Value Diastolic BP (mmHg) | Meaning | Zone | Example User Text | |
|---|---|---|---|---|---|
| <130 | and | <85 | Normal | Green | Your blood pressure is within the normal range. Maintaining a healthy lifestyle helps keep it stable. |
| 130-139 | and/or | 85-89 | High Normal | Yellow | Your blood pressure is elevated. Regular exercise and a balanced diet can help maintain healthy levels. |
| >139 | and/or | >89 | Hypertensive range | Red | Your blood pressure is high. A single measurement is not sufficient to assess further steps, but it is advised to keep tabs on your blood pressure values and verifying it with a dedicated blood pressure monitor. Refer to the hypertension risk metric for a more comprehensive indicator of hypertension. Consult a healthcare provider in case your values remain high. |
