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.

摘要： A method, system and computer program product are provided for evaluating whether an oscillometric signal representative of pressure oscillations in the vasculature of a patient is associated with special conditions that may lead to inadvertently identifying the signal as being indicative of peripheral arterial disease or non-analyzable. In one embodiment, the method includes obtaining an oscillometric signal at a location on an extremity of the patient, determining a ratio using a value associated with a first frequency component of the oscillometric signal and a value associated with a second frequency component of the oscillometric signal, comparing the ratio to a threshold value, associating a first diagnostic class with the oscillometric signal when a first outcome results from comparing the ratio to a threshold value, and associating a second diagnostic class with the oscillometric signal when a second outcome results from comparing the ratio to a threshold value.

摘要： The present invention provides apparatuses and methods that facilitate the determination of a hydrostatic correction factor usable in an EBPR examination of a patient in a non-supine position. In one embodiment, a first blood pressure measuring device may be positionable on a first extremity of the patient, and a second blood pressure measuring device may be positionable on a second extremity of the patient, with one of the blood pressure measuring devices being located above the other one. The apparatus includes a computational device and an input element coupled to the computational device, wherein information relating to a vertical distance between the first and second blood pressure measuring devices is receivable by the input element. The computational device is operable to calculate at least one of a hydrostatic correction factor, a corrected extremity blood pressure, and an extremity blood pressure ratio using the information relating to the vertical distance.

摘要： The present invention provides methods that facilitate the determination of a hydrostatic correction factor usable in an EBPR examination of a patient in a non-supine position. In one embodiment, a method for facilitating the determination of a hydrostatic correction factor for an extremity blood pressure ratio examination of a patient in a non-supine position includes establishing the vertical distance between first and second blood pressure measuring devices positionable on first and second extremities of the patient based on an empirically derived formula and determining a hydrostatic correction factor for the extremity blood pressure ratio examination based on the vertical distance. In this regard, the formula for the vertical distance may be based on a percentage of the height of the patient.
