摘要:
The invention provides a system and method for measuring vital signs (e.g. SYS DIA SpO2 heart rate and respiratory rate) and motion (e.g. activity level posture degree of motion and arm height) from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient’s heart and (ii) at least three motion-detecting sensors positioned on the forearm upper arm and a body location other than the forearm or upper arm of the patient. Each motion-detecting sensor generates at least one time-dependent motion waveform indicative of motion of the location on the patient’s body to which it is affixed. A processing component typically worn on the patient’s body and featuring a microprocessor receives the time-dependent waveforms generated by the different sensors and processes them to determine: (i) a pulse transit time calculated using a time difference between features in two separate time-dependent waveforms a blood pressure value calculated from the time difference, and a motion parameter calculated from at least one motion waveform.
