Systems and methods for non-invasive blood pressure measurement

Systems and methods for non-invasive blood pressure measurement are disclosed. In some embodiments, a system comprises a wearable member configured to generate first and second signals (e.g., PPG signals), and a blood pressure calculation system including a wave selection module, a feature extraction module, and a blood pressure processing module configured to calculate an arterial blood pressure value based on the sets of feature vectors and an empirical model.
