Abstract
One aspect of the subject matter described in this disclosure can be implemented in a device capable of use in estimating blood pressure. The device includes one or more arterial sensors configured to obtain arterial measurements at two or more elevations. The device additionally includes one or more processors configured to determine one or more calibration parameters for a first blood pressure model based on the arterial measurements and a hydrostatic pressure difference between at least two of the elevations. The processors also are configured to determine a first blood pressure based on the first blood pressure model, the calibration parameters and the arterial measurements. The processors also are configured to determine a second blood pressure based in part on a second blood pressure model, one or more calibration parameters and the arterial measurements. The processors are further configured to provide a final blood pressure based on the first and second blood pressures.
