1. A system for continuously monitoring a plurality of patients, the system comprising:

  • a patient monitor configured to be worn on the body of each of the plurality of patients, each patient monitor comprising;

    a first sensor comprising a first detector configured to detect a first time-dependent physiological waveform indicative of one or more contractile properties of the patient'"'"'s heart;

    a second sensor comprising a second detector configured to detect a second time-dependent physiological waveform indicative of one or more contractile properties of the patient'"'"'s heart;

    at least two motion-detecting sensors positioned on locations selected from a forearm, upper arm, and a body location other than the forearm or upper arm of the patient, each of the motion-detecting sensors generating at least one motion waveform indicative of motion of a body location onto which the motion-detecting sensor is affixed;

    a location sensor comprising a wireless component and a location processing component, the location processing component configured to receive a signal from the wireless component and process this signal to determine a physical location of the patient to which the location sensor is attached;

    a processing component configured to receive the time-dependent physiological and motion waveforms and determine therefrom;

    (i) at least one vital sign calculated using at least one of the first and second time-dependent physiological waveforms;

    (ii) at least one motion parameter selected from the patient'"'"'s posture, activity state, and degree of motion calculated using at least one motion waveform generated by each of the motion-detecting sensors; and

    (iii) an alarm parameter calculated from the at least one of the vital sign and motion parameter; and

    ,a wireless transceiver configured to wirelessly transmit the vital sign, motion parameter, location of the patient, and alarm parameter through a wireless system; and

    ,a remote computer system comprising a display and an interface to the wireless system, the interface configured to receive from the wireless system a vital sign, motion parameter, location of the patient, and alarm parameter corresponding to each of the plurality of patients comprising a patient monitor, and the display configured to render a user interface that describes at least one of a vital sign, motion parameter, location of the patient, and alarm parameter for each patient of the plurality of patients comprising a patient monitor.
