Key result
Continuous blood pressure estimation from smartphone-acquired heart sound signals correlated with a commercial device (mean r=0.707-0.748) with mean errors <5 mmHg.
Why the study?
Does continuous blood pressure estimation from smartphone-acquired heart sound signals accurately reflect commercial device measurements in healthy subjects?
Observational (n=32)
Does continuous blood pressure estimation from smartphone-acquired heart sound signals accurately reflect commercial device measurements in healthy subjects?
Smartphone-acquired heart sound signals can estimate continuous blood pressure with reasonable accuracy, offering a potential tool for inexpensive, cuffless home monitoring.

Not ready for clinical use; leaves open validation of smartphone heart sound signals for continuous BP monitoring.
Peng et al. (2015) conducted an observational in Healthy (n=32). Continuous blood pressure estimation from heart sound signals using a smartphone vs. Commercial device to measure continuous blood pressure was evaluated on Correlation coefficients and mean errors for systolic, diastolic, and mean blood pressure. Continuous blood pressure estimation from smartphone-acquired heart sound signals correlated with a commercial device (mean r=0.707-0.748) with mean errors <5 mmHg.
