ABSTRACT:
An automated sphygmomanometer which stores the attributes for all oscillation complexes at each pressure step and compares the stored waveform data to a template containing the attributes of a "clean" oscillation complex from a present or previous NIBP determination or from a standard template determined from a broad population of patients. Preferably, an oscillation complex near MAP is selected as the template. After the oscillation complexes have been gathered, correlation values for each new oscillation complex in the stored waveform data and the template are calculated using correlation calculations from detection theory. All oscillation complexes which highly correlate with the template (their correlation values are above a given threshold) are maintained as "good" oscillation data, while the remainder of the oscillation complexes are ignored as corrupted by artifact data. Artifact-reduced data may then be used in the blood pressure calculation. Similar correlation techniques are also used at each pressure step in a real-time manner to detect the presence of an oscillation complex during a step inflate or deflate blood pressure measurement.
