Abstract :
A near-optimum motion artifact filter which permits oscillometric occlusion pressure determinations to be performed under conditions of moderate surgical limb manipulation is presented. The authors outline the development of the filter and compare its signal-to-noise ratio (SNR) performance to that achieved by patient-specific optimum digital filters. Experiments show that for the oscillometric signals studied, the patient-specific optimum filter can be replaced by a single analog filter with little degradation in motion artifact suppression
