Where are specialist mental health clinics typically held?
Specialist mental health clinics are typically held in local medical practices, community centers, and not just in hospitals.
What kind of data does the insulin pump control system collect?
Data from a blood sugar sensor
What is the calculation based on for determining the amount of insulin to be injected?
Rate of change of blood sugar levels
Why is the insulin pump control system considered a safety-critical system?
Low blood sugars can lead to brain malfunctioning, coma, and death; high-blood sugar levels have long-term consequences.
What action does the insulin pump control system take after calculating the required insulin dose?
Sends signals to a micro-pump to deliver the correct dose of insulin
How does the insulin pump control system help maintain blood glucose control in diabetics?
By delivering the correct dose of insulin based on blood sugar levels
What are the potential consequences of high-blood sugar levels if not managed by the insulin pump system?
