Abstract:
1. A system for measuring a blood pressure from a patient, comprising: (a) a first sensor configured to generate a first time-dependent waveform indicative of one or more contractile properties of the patient's heart; (b) an electrical sensor comprising: at least two electrodes configured to detect electrical signals from the patient's body, and an electrical circuit operably connected to the electrodes and configured to process the detected electrical signals, the electrical sensor generating a time dependent electrical waveform indicative of one or more contractile properties of the patient's heart; (c) at least two motion-detecting sensors positioned on separate locations on the patient's body, each of said motion-detecting sensors generating at least one time-dependent motion waveform indicative of motion of the location on the patient's body to which the motion detecting sensor is affixed; and, (d) a processing component configured to be worn on the patient's body and comprising a microprocessor, said processing component configured to receive the first time-dependent waveform, the time-dependent electrical waveform, and the at least one time-dependent motion waveform generated by each motion-detecting sensor, and to determine:
