Does smartphone-based photoplethysmography accurately measure heart rate metrics compared to a standard pulse oximeter?
Effect estimate: r=0.967
A smartphone-based PPG system using digital signal processing provides highly accurate heart rate measurements comparable to a standard pulse oximeter, offering a low-cost monitoring solution.
Jakarbet et al. (2025) studied Cardiovascular monitoring. Smartphone-based photoplethysmography (PPG) vs. Pulse oximeter was evaluated on Predictive accuracy and correlation with pulse oximeter (r=0.967). A smartphone-based photoplethysmography framework demonstrated strong predictive accuracy (MAE 3.93, MAPE 4.96%) and high correlation (r=0.967) against a standard pulse oximeter.
