Fewer carers & lower social and
health insurance income

Increased prevalence and
earlier onset of chronic diseases
Connected freedom
Healthcare is changing
> Healthcare infrastructure was set up to manage
acute illness, today 70 to 80% of the healthcare
budget is spent on chronic diseases.
> Better more flexible monitoring of patients
> Migration of the care from the hospital to the
home

Patient Monitoring: Early Warning
> BMJ on Early Warning Scores: 84% of patients had
documented observations of clinical deterioration
within eight hours of cardiopulmonary arrest”
> RM Schein 1990: 70% of patients have respiration
problems 8 hours before circulation stops
> C Franklin 1994: 66% of patients show abnormal
symptoms 6hrs before circulation stops
> The doctor was warned in 25% of cases

Connected freedom
Patient monitoring today
> Cable management, infection control
> Care areas, patient comfort and distress

Connected freedom
Medical Body Area Networks (MBAN)
a network of wireless sensors around the body
> Clinical Benefits
> Patient mobility and comfort
> Monitoring flexibility
> extending monitoring into all care
areas.
> Infection control
> Low cost disposable monitors
> Patient identification and tracking

MBAN Challenges
Robust wireless links
Capacity for Patient and Sensor density
Co-existence with other radios and networks
Days of continuous use from small light weight
devices (batteries)

Future MBANs :IEEE 802.15.TG6 (MedWin)
> Members: Toumaz, GE Healthcare, Philips
Healthcare, Texas Instruments.
> FCC new MBAN service 2360 to 2400MHz band
> 2360-2390 MHz MBANS operations limited to health care facilities outside
exclusion zones (indoor use only)
> 2390-2400 MHz MBANS operations permitted anywhere (all hospitals, in-home,
mobile ambulances, …)
