METHOD FOR OSCILLATORY NON-INVASIVE BLOOD PRESSURE (NIBP) MEASUREMENT AND CONTROL UNIT FOR AN NIBP APPARATUS

摘要

There is provided a method for use in cuff-based oscillatory non-invasive blood pressure (NIBP) measurement. The method comprises: progressively altering the volume of air in a cuff of a NIBP measurement apparatus during a measurement period; obtaining a plurality of measurements of the flow rate of the air into/out of the cuff during the measurement period; obtaining a plurality of measurements of the air pressure in the cuff during the measurement period; and determining a relationship between quasi-static cuff compliance and cuff pressure by calculating the quasi-static cuff compliance at a plurality of instances during the measurement period, based on the flow rate measurements and the air pressure measurements obtained during the measurement period.
