Abstract
In an electronic blood pressure meter, there are included a cuff adapted to be fitted around the arm of a patient whose blood pressure is to be measured and formed with a cavity, a device for pressurizing the cavity in the cuff, a device for gradually depressurizing the cavity in the cuff, a device for sensing the pressure in the cavity in the cuff and for producing an output signal representative thereof, a device for detecting a pulse wave component in the output signal produced by the sensing device, a device for determining the amplitude of the thus detected pulse wave component, a device for determining values for systolic blood pressure and diastolic blood pressure according to the thus determined amplitude of the pulse wave component and according to the output signal produced by the pressure sensing device, and a device for performing compensation relating to the values for systolic blood pressure and diastolic blood pressure. Optionally, the means for performing compensation relating to the values for systolic blood pressure and diastolic blood pressure may include a device for determining a compensation parameter and a device for compensating the amplitude of the pulse wa…
