A medical system includes a plurality of portable vital sign monitors (12), a patient assessment unit (24), a patient watch-dog unit (42), and at least one display device (44). Each monitor continuously monitors vital signs of a subject (12) from a point of initial contact with a healthcare professional and wirelessly transmits the monitored vital signs, and the vital signs include blood pressure (BP), blood oxygen (SpO2), heart rate (HR), and respiratory rate (RR). The patient assessment unit (24) receives the transmitted monitored vital signs of each subject and determines a triage score based on the received vital signs, and subject gender, subject age, and subject symptoms. The patient watch-dog unit (42) constructs a display of a patient trajectory of each subject and the trajectory includes the monitored vital signs, the determined triage score, and the subject gender, the subject age, and the subject symptoms. The at least one display device (44) display the constructed patient trajectory of at least one subject.
