Abstract:
1. A non-invasive blood pressure measuring system comprising: a single pressure transducer configured to obtain pressure data at each of a plurality of decreasing pressure steps, said pressure data at each decreasing pressure step including a transient baseline effects component; and A processor adapted to receive the pressure data obtained by the single pressure transducer at each of the plurality of decreasing pressure steps, said processor being configured to generate a transient baseline effects model at each pressure step based on the pressure data obtained by the single pressure transducer, said processor further being configured to implement the transient baseline effects model to at least partially remove the transient baseline effects component from the pressure data received from the single pressure transducer at each one of the plurality of decreasing pressure steps, wherein the processor estimates a blood pressure parameter from the pressure data, obtained by the single pressure transducer at each one of the plurality of decreasing pressure steps after removal of the transient baseline effects component; wherein the removal of the transient baseline effects component from the pressure data obtained at each of the plurality of decreasing pressure steps eliminates a potential source of error and thereby enables a more accurate blood pressure estimate.
