1. An ambulatory patient monitoring system for measuring and storing a plurality of blood pressure values powered by a portable power source, comprising:

  • a portable housing coupled to a patient, said portable power source being disposed within said portable housing;

    microprocessor means disposed within said portable housing and coupled to said portable power source for (1) generating an inflate command control signal, (2) generating a deflate command control signal, and (3) determining said blood pressure values;

    memory means disposed within said portable housing and coupled to said microprocessor means for storing said plurality of blood pressure values;

    optical interface means disposed within said portable housing and coupled to said microprocessor means for receiving at least one control signal from an external monitoring unit, said microprocessor means generating said inflate command signal to initiate a blood pressure measurement responsive to receipt of said control signal from said external monitoring unit;

    transducer means coupled to said microprocessor means for providing measurement data thereto, said microprocessor means calculating said blood pressure values from said measurement data, said transducer means including an inflatable cuff for occluding an artery of a patient;

    inflation means coupled in fluid communication with said inflatable cuff and coupled to said microprocessor means for inflation of said inflatable cuff responsive to said inflate command control signal from said microprocessor means; and

    ,deflation means coupled in fluid communication with said inflatable cuff and coupled to said microprocessor means for deflation of said inflatable cuff responsive to said deflate command control signal from said microprocessor means.
