Abstract
A system and method for processing oscillometric data from a plurality of pressure steps to determine the blood pressure of a patient. A heart rate monitor connected to the patient acquires the patient's heart rate. A time-to-frequency domain converter receives oscillometric data and converts the oscillometric data into the frequency domain. Based upon the calculated heart rate, the system and method filters the frequency domain oscillometric signal with pass bands centered at the fundamental frequency and at least one fundamental frequency. The energy of the frequency domain signal within the pass bands is compared to at least a portion of the energy of the frequency domain oscillometric signal outside of the pass bands. Based upon the comparison, the signal determines whether the signal at the current pressure step should be utilized in calculating the blood pressure of the patient.
