1. A pressure sensing apparatus comprising:

  • a pressure sensor component having a pressure sensing port, a pressure sensor for sensing a pressure of a fluid in the pressure sensing port, and a digital processor communicating with the pressure sensor for performing calculations involving fluid pressures sensed;

    a first chamber in fluid contact with the pressure sensing port;

    a second chamber fluidically connectable with a patient'"'"'s cerebrospinal fluid system; and

    a membrane located between the first and second chambers so as to transmit fluid pressure from the second chamber to the first chamber.
