Body-worn vital sign monitor

A system for monitoring vital signs from a group of patients, comprising:

• (a) a monitoring device configured to be worn on the body of each patient in the group, each monitoring device comprising:
• a wireless system;
• a first sensor configured to generate a first time-dependent waveform indicative of one or more contractile properties of the patient's heart;
• a second sensor configured to generate a second time-dependent waveform indicative of one or more contractile properties of the patient's heart;
• and
• a processing component configured to:
• (i) receive a first signal representing the first time-dependent waveform;
• (ii) receive a second signal representing the second time-dependent waveform;
• (iii) calculate a blood pressure value from a pulse transit time measured between the first and second signals or versions thereof;
• and (iv) transmit the blood pressure value with the wireless system;
• and
• (b) a remote display device in communication with each monitoring device through the wireless system comprised by the monitoring device, the remote display device configured to simultaneously display a blood pressure value for each patient in the group when a signal strength corresponding to the wireless system comprised by each monitoring device is below a pre-determined threshold value, and further configured to automatically reconfigure the display device to display a blood pressure value for only a particular patient when the signal strength from the wireless system worn by the particular patient exceeds the pre-determined threshold.
