<p>PROBLEM TO BE SOLVED: To provide equipment for measuring peripheral venous pressure and its method with which anyone can measure peripheral venous pressure easily in a non-invasive way. SOLUTION: A cuff is put around the upper arm. After increasing the external pressure of the cuff, cuff pressure is measured during a process of slowly reducing the external pressure of the cuff. Simultaneously, a sensor for peripheral venous pressure is attached to a peripheral part rather than a part where the cuff is put, and peripheral venous pressure or relative values are found, corresponding to the changes in cuff pressure. A peak of the peripheral venous pressure or the relative value is found, and the cuff pressure which corresponds with the peak of the peripheral venous pressure is considered as the maximum peripheral venous pressure.</p> |
