1. A physiological sensor comprising:

  • an optic assembly having an optic transducer;

    an acoustic assembly having an acoustic transducer;

    an attachment assembly that affixes the optic assembly and acoustic assembly to a tissue site;

    the optic assembly activated so that the optic transducer transmits a plurality of wavelengths of light into the tissue site and detects the light after attenuation by pulsatile blood flow within the tissue site so as to generate an optic signal;

    the acoustic assembly activated so that the acoustic transducer responds to vibrations at the surface of the tissue site so as to generate an acoustic signal; and

    a sensor cable that transmits the optic signal and the acoustic signal to a monitor for calculation of a plurality of physiological parameters.
