Ayushman A Pervasive Healthcare System
Sanskrit for long life

• Project _at_ IMPACT Lab, Arizona State University
• To provide a dependable, non-intrusive, secure,
  real-time automated health monitoring.
• Should be scalable and flexible enough to be used
  in diverse scenarios from home based monitoring
  to disaster relief, with minimal customization.

Vision

• To provide a realistic environment (test-bed) for
  testing communication
• protocols and systems for medical
  applications.

Ayushman Remote Medical Monitoring

• Testbed consists of medical devices interfaced
  using crowssbow motes to a PDA.
• Medical devices integrated include BP monitor
  (Suntech), EKG monitor (Vernier) and Gait Monitor
  (Mica2 based sensors). 

BP and EKG Monitoring

• Supports query based and continuous data
  collection.
• Implements caching aggregation.
• System Constrainst
• Low reliability
• Lack of bandwidth
• Low memory for processing.

Current Work

• Develop a effective visualization tools for
  medical data
• Integrate multi-interface based star-gate for
  local gateway
• Develop performance management infrastructure
• Monitoring, Visualizing sensor performance
• Controlling sensors to tune performance according
  to our needs.
