Research output: Patent


A cardio-respiratory monitoring system comprises a patient interface, a monitoring device and a processor. The monitoring device comprises a gyroscope mounted on the patient interface so as to generate a ballistocardiography signal when a patient is wearing the patient interface. The processor is configured to analyse the ballistocardiography signal to estimate a heart rate of the patient. In one form of the technology the analysis carried out by the processor comprises partitioning the ballistocardiography signal into non-overlapping windows, detecting one or more peaks within a window, and estimating the heart rate as a reciprocal of the duration between consecutive detected peaks.
