Abstract

The invention is a system and apparatus for screening out blood pressure measurements that are inaccur-ate because of the presence of artifact while allowing such measurements to be utilized if they are accurate despite the presence of artifact. The apparatus is a blood pres-sure monitor having a blood pressure cuff and air pump and valve pneumatically coupled to the cuff. A pressure transducer pneumatically coupled to the cuff generates a signal representative of the air pressure in the cuff and a signal corresponding to pulses in the cuff. A processor responds to the transducer signal and energizes the air pump to inflate the cuff, periodically energizing the valve to reduce air pressure. The processor in response to the measurements made calculates blood pressure parameters and compares them with recorded parameters to determine whether artifact has affected the accuracy of any recorded pres-sure.
