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

Patient monitoring today
>Cable management, infection control>Care areas, patient comfort and distress
Connected freedomPage 6
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

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, …)
