Description
Summary:A new technique for swiftly determine a servo reference value (Vo) of the volume-compensation method was developed. To determine the Vo values, high frequency vibration (frequency: 20 Hz, pulse pressure: 10 mmHg) was superimposed on cuff pressure (Pc), and artificially produced arterial wall oscillation was detected as photoplethys-mographic (PG) pulsation signal. In this signal, maximum oscillation points were observed when the mean value of Pc is equal to blood pressure, and Vo value was then determined from the mean level of PG signal at this maximum point. The values obtained by this method coincide well with those obtained by the previous method (the volume-oscillometric method), indicating the validity of the present method.
