1. A system for monitoring a patient, comprising:

  • a processing system configured to be worn on a patient'"'"'s body comprising at least three serial ports and a processor in electrical communication with each serial port, each serial port configured to receive a digital data stream from a unique sensor worn on the patient'"'"'s body;

    an ECG system comprising;

    i) a connecting portion configured to connect to a plurality of electrodes configured to be worn on the patient;

    ii) a differential amplifier configured to receive electrical signals from each of the plurality of electrodes and process them to generate an analog ECG waveform;

    iii) an analog-to-digital converter configured to convert the analog ECG waveform into a digital ECG waveform;

    iv) and a transceiver component configured to transmit a digital ECG data stream comprising the digital ECG waveform or information calculated therefrom through a first serial port and to the processing system;

    an oscillometry system comprising;

    i) a cuff configured to be worn on the patient and apply pressure to a portion of the patient;

    ii) a pneumatic system configured to inflate the cuff and detect pressure therein representing an analog oscillometric waveform;

    iii) an analog-to-digital converter configured to convert the analog oscillometric waveform into a digital oscillometric waveform;

    iv) a transceiver component configured to transmit a digital oscillometric data stream comprising the digital oscillometric waveform or values calculated therefrom through a second serial port and to the processing system; and

    a third system configured to generate a third digital data stream and transmit the third digital data stream or values calculated therefrom through a third serial port to the processing system.
