3. Medical Body Area Network (MBAN) - A wireless network of sensors around a patient to provide monitoring services PM in General Wards PM in High Acuity Areas • Clinical benefits • Extension of monitoring into care areas that are currently unmonitored • Improve healthcare workflow efficiency, safety and clinical outcome. • Patient mobility, comfort, infection control • Monitoring flexibility and scalability • Reduced overall monitoring costs • EHR support MBAN Remote Home PM Mobile Ambulance PM Dave Evans, Philips

4. Proposed Regulation on Usage of MBANS Spectrum • Eligibility & Permissible Communications • Licenses by rule operations by authorized health care professionals and by any other person, if such use is prescribed by a health care professional.  Limited to transmission of data (no voice) used for monitoring, diagnosing or treating patients by duly authorized healthcare professionals. • Frequencies & Authorized Locations • 2360-2390 MHzMBANS operations in the 2360-2390 MHz band limited to health care facilities only. Healthcare facility MBANS registration/coordination and electronic key/beacon MBANS device control mechanism needed to access part or all of the 2360-2900 MHz band. • 2390-2400 MHzoperations permitted anywhere Citizen’s Band (CB) radios may operate, including healthcare facilities, ambulances, and patient homes. • Technical Parameters • All stations must employ unrestricted contention-based protocol.  • Maximum emission bandwidth (20-dB emission BW) of 5 MHz. • Maximum EIRP not to exceed the lesser of 1 mWand 10 log (B) dBm in the 2360-2390MHz band and the lesser of 20mWand 16 + 10 log (B) dBm in the 2390-2400MHz band, where B is the 20-dB emission BW. • Only medical applications would be allowed • Both in-hospital and remote monitoring applications would be eligible Dave Evans, Philips

5. In-hospital Applications • Applications • Critical care monitoring services • Intensive Care Units (ICUs), Operating Rooms (ORs), Post-Anesthesia Care Units (PACUs), Emergency Rooms (ERs) Medical/Surgery, maternity, radiology • Monitoring in general wards • Transport, recovery rooms, step down areas, wireless cardiac monitoring • Monitoring in ambulance • Huge potential market • 5,747 acute care hospitals in US (based on 2008 statistics) • 879,105 staffed beds • 56% are monitored (492,298 beds) • MBANS would simplify patient care and reduce costs • 44% are unmonitored (386,806 beds) • Low & medium acuity cableless PM and PM in general wards • 1500+ Rapid Response Teams • Reduction in unplanned ICU admissions • Reduction in healthcare costs Dave Evans, Philips

6. In-hospital System Architecture Patient worn sensor devices … SpO2 Blood Pressure ECG MBANS short range radios Bed side Monitor Patient worn hub device Wi-Fi, WMTS or other long-rang radios Remote central station Dave Evans, Philips

7. General Requirements of In-hospital Applications • General Parameters • Data rates from bps to kbps per sensor • Usually in-room service • TX/RX in a same room with a range <= 3m • Low duty cycle • <25%, with a typical value of ~10% or less • Robust link performance needed • Long battery life • Several days or even weeks • Deployment density • Usually < 10 MBANS networks coexisting with each other • Low cost • Commercial off the shelf radios Dave Evans, Philips

8. Remote Home Healthcare Applications • Applications • Extended care into the patient’s home during the critical time after a hospitalization episode • Shortened hospital stay, reduced re-hospitalization rate • Chronic disease management monitoring systems • Cardiac conditions, mostly notably congestive heart failure (CHF), diabetes, asthma, and chronic obstructive pulmonary disorder (COPD) Dave Evans, Philips

9. General Requirements of Remote Home Healthcare Applications • General Parameters • Data rates from bps to kbps per sensor • Large coverage preferred (multi-room coverage) • TX/RX may not in a same room • Extremely low duty cycle • Usually ~2% or less • Long measurement period or event driven data communications • Robust link performance needed • Long battery life • Several days or even weeks • Low deployment density • Usually ~2 or fewer MBANS networks at a same location • Low cost • Commercial off the shelf radios Dave Evans, Philips
