Medical information tags

• miTag medical information tag
• real-time capture of vital signs
• 500M storage of patient history
• 5 day battery life
• Simultaneous monitoring of up to 950 patients
• miView monitoring station
• Pulse and SpO2
• Locality (uses checkpoints)
• Send/receive messages to patients
• Manual inputs pain, triage assessment

miView USB turns a laptop into a patient tracking
station

Wireless Sensors in Medical Emergencies

• Wireless networks in Emergency Medicine is
  challenging because
• Unpredictably large numbers of patients
• No time to deploy network infrastructure
• Patients move beyond network coverage
• How do we reliable network coverage in chaotic
  disasters?
• Install the receiver plug USB into laptop,
  install miTag gateway software
• Install the server install server on laptop or a
  server machine
• Deploy network repeaters plug into wall outlets
  every 20 meters indoors

Response to Mass Casualties Today

• Problems
• archaic technologies
• limited communication infrastructure
• overwhelmed staff

What if radical changes in technology could
revolutionize patient care?
5
Technology Enabled Scenarios

• FUTURE
• Everyone tracked by miTags that automate triage
• Responders access real-time information on
  handheld devices and websites
• Patients are automatically tracked vitals,
  transport location, decontaminations status

User Scenarios in Disaster Response

• 1. Department of Homeland Security
• Disaster Drill Results showed that time to triage
  a patient using miTags vs paper tags are
  equivalent
• Using miTags showed increased responders ability
  to make more patient assessments (by over 200)
• Using miTags decreases the number of radio calls
  made by responders (by up to 50)

• 2. Maryland Auxiliary Care Center
• Care center personnel log onto website to view
  real-time information of incoming patients
• Monitor and track patients at the care center

miView Dashboard of your ED Census

• Sort patients by
• Triage level
• IDs
• Vitals

9
miView communicate with patients

• Automatically track patient location
• Automatically monitor vital signs
• Send messages to patients

10
Application ED Patient Monitoring

• Usage
• Attach miTag to Priority 2,3,4 patients during
  Initial Triage
• miTag data is integrated with hospital EMR
• Users access miTag data either on their software
  applications or on miView
• Benefits
• Earlier identifications of deteriorations
• Compliance with The Joint Commission (JCAHO) by
  regularly recording heart rate, O2, and Pain
  score
• Get Census of ED patients from a single dashboard
