  • Noninvasive apparatus and method for estimating blood pressure
    Patent number: 7828740
    Abstract: Methods and apparatus for noninvasively estimating a blood pressure are provided. A pulmonic (P) component extracted from a second heart sound (S2) signal is analyzed to obtain a number of oscillations in the P component. A predetermined relationship between the number of oscillations and PAP is used to generate a blood pressure estimate. A PCG sensor including a mechanical filter for receiving heart sounds from a chest wall is also provided. The pressure of the PCG sensor on the chest wall is adjustable.
