PanGo Focus and DirectionPanGo Focus and Direction
• PanGo provides:
- An Wi-Fi-based asset tracking application that allows customers to locate, track and better manage critical resources (e.g., equipment and people)
- A Location Management Platform that allows technolgy providers and system integrators to capture and integrate location and state information into hospital workflow and information systems

• Radio Frequency Identification (RFID) definition: - A system that allows tracking tags to store, send and receive
data through use of radio signals
• RFID technologies provide answers to what, where, when:- Asset/Product Data and Status- Location Data- Event Time
• RFID technology also enables real-time visibility of physical things within an organization and across supply chains

Continuum/Hierarchy of NeedsContinuum/Hierarchy of Needs
Who is patient John Doe? Is this medication from Lot #123?
Where is the medication cart? Where is patient John Doe?
Is the flow rate on the IV pump O.K.? Is the ventilator functioning correctly?
If the glucometer gets dropped, disable it. If the cart has bad medication on it, lock the door.
PanGo is initially focused on satisfying the need for location.

Passive and Active RFID are ComplementaryPassive and Active RFID are Complementary
Passive RFID• Visibility: Chokepoints and
scans (barcode replacement)
• Reader looks for tags
• Low-cost tags (<$.5)
• Low range (inches)
• Disposable tags
• High volumes/consumables
Active RFID• Visibility: Real-Time Tracking
• Battery-powered tags send signals to APs/readers
• Higher-cost tags ($50-100)
• Long range (hundreds of feet)
• Reusable tags
• Lower volume/high value

Wi-Fi-Based Proprietary
• Leverage existing 802.11 WLAN for location determination and data backhaul
• Broad applications – wherever WLAN is deployed
• Rapidly shrinking costs due to 802.11 standards-driven cost/performance curves
• Ability to track laptops, PDAs, tablets and other wireless-enabled devices/equipment without using tags
• Requires installation of an additional network infrastructure (for location determination)
• Expensive, single-use, proprietary hardware (readers, wiring, etc.)
• Need for ongoing infrastructure maintenance and support
Avoid proliferation of redundant networks!

How are hospitals using Wi-Fi and Active RFID?How are hospitals using Wi-Fi and Active RFID?
• Real time point of care data connectivity- Physician/Provider Order Entry
- Electronic Medical Record
• Timely communication with caregivers- “Smart Badge” VoIP over Wi-Fi (VoWiFi)
• Asset tracking of biomedical equipment
• Locating people, caregivers and patients
• Security

Knowing the location of people and assets can assist greatly with “Environment of Care” compliance
Knowing the location of people and assets can assist greatly with “Environment of Care” compliance
• The Joint Commission of Accreditation of Healthcare Organizations (JCAHO) identifies the following areas of interest in their "Environment of Care" standard:- Safety Management- Security Management- Hazardous Materials and Waste Management- Emergency Management- Fire/Life Safety- Medical Equipment Management- Utilities Management
• All these areas can benefit from knowing where people and assets are located…in real time

Hospital Challenge: Asset InvisibilityHospital Challenge: Asset Invisibility
Not knowing where valuable equipment and key people are when they are needed
Excess equipment leases and purchases
Compromised patient care resulting from longer wait times
Wasted time searching for people and equipment
Loss/theft of critical equipment
Inefficient management of personnel, bed, equipment and systems capacity
