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

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
