摘要：
Systems, methods, and products for determining indicated blood pressure values and/or characterizing a condition of a patient. The systems, methods, and products are capable of determining indicated blood pressure values in a lower extremity of a patient using an oscillometric technique. An oscillometric signal obtained from the lower extremity of the patient is analyzed, and the patient may be classified into one of a plurality of diagnostic classes. Each diagnostic class may have an associated ratio value. Based on the diagnostic class into which the patient is classified, a selected lower extremity characteristic ratio may be selected. A lower extremity indicated blood pressure value may be obtained by oscillometric processing using the selected ratio. This lower extremity indicated blood pressure value may be used with an upper extremity indicated blood pressure value to perform an extremity blood pressure ratio (EBPR) examination.
