Key result
Cuffless blood pressure estimation using a single-sensor photoplethysmogram achieved a mean absolute error of 4.92 mmHg for diastolic and 8.89 mmHg for systolic blood pressure.
Why the study?
Accurate cuffless and continuous non-invasive estimation of blood pressure is needed for preventing and managing cardiovascular disease.

Does a cuffless PPG-based estimation method accurately measure blood pressure in patients?
Effect estimate: MAE 4.92 mmHg for DBP and 8.89 mmHg for SBP
A novel cuffless blood pressure estimation method using a single optical PPG sensor showed promising accuracy, with mean absolute errors of ~5 mmHg for DBP and ~9 mmHg for SBP.
Samimi et al. (2022) studied this question. Cuffless blood pressure estimation using photoplethysmogram (PPG) was evaluated on Mean error (ME) and mean absolute error (MAE) for diastolic and systolic blood pressure (MAE 4.92 mmHg for DBP and 8.89 mmHg for SBP). Cuffless blood pressure estimation using a single-sensor photoplethysmogram achieved a mean absolute error of 4.92 mmHg for diastolic and 8.89 mmHg for systolic blood pressure.
