Hydration monitoring

Abstract

Systems and techniques for monitoring hydration. In one implementation, a method includes measuring an electrical impedance of a region of a subject to generate an impedance measurement result, and wirelessly transmitting the data to a remote apparatus. The probe with which impedance is measured may in the form of a patch adhesively secured to the subject.

1 . A system for ambulatory physiological monitoring comprising: 
 at least one adhesive patch positioned on at least a portion of a subject, said patch comprising a plurality of sensors and at least one communication module, said sensors being configured to sense one or more physiological parameters comprising at least electrical impedance;    a data collection unit configured to receive information collected from said sensors from said communication unit.    
     
     
         2 . The system of  claim 1 , additionally comprising a remote data management system configured to receive information from said data collection unit and process said information.  
     
     
         3 . The system of  claim 1 , wherein said adhesive patch is secured to at least a portion of a thorax of said subject.  
     
     
         4 . The system of  claim 1 , additionally comprising a temperature sensor.  
     
     
         5 . The system of  claim 1 , additionally comprising a subsurface temperature sensor.  
     
     
         6 . The system of  claim 1 , wherein said data collection unit is also configured to process information before sending information to said remote data management system.  
     
     
         7 . The system of  claim 1 , comprising a timer for associating at least one measurement with an absolute time the measurement was taken.  
     
     
         8 . The system of  claim 1 , wherein said remote database is configured to establish an individual baseline parameter value.  
     
     
         9 . The system of  claim 1 , wherein the data management system provides feedback to the data collection unit and/or the communication module.  
     
     
         10 . The system of  claim 1 , wherein said feedback comprises diagnostic knowledge.  
     
     
         11 . The system of  claim 1 , wherein said feedback comprises actions and/or instructions.  
     
     
         12 . The system of  claim 1 , comprising a plurality of communication modules.  
     
     
         13 . The system of  claim 1 , comprising a plurality of data collection units.
