You are hired to develop an automatic patient monitoring system for a home-bound patient. The system is required to read out the patient’s heart rate and blood pressure and compare them against specified safe ranges. The system also has activity sensors to detect when the patient is exercising and adjust the safe ranges. In case an abnormality is detected, the system must alert a remote hospital. (Note that the measurements cannot be taken continuously, since heart rate
You are hired to develop an automatic patient monitoring system for a home-bound patient. The system is required to read out the patient’s heart rate and blood pressure and compare them against specified safe ranges. The system also has activity sensors to detect when the patient is exercising and adjust the safe ranges. In case an abnormality is detected, the system must alert a remote hospital. (Note that the measurements cannot be taken continuously, since heart rate is measured over a period of time, say 1 minute, and it takes time to inflate the blood-pressure cuff.)
The system must also
(i) check that the analog devices for measuring the patient’s vital signs are working correctly and report failures to the hospital; and,
(ii) alert the owner when the battery power is running low. Enumerate and describe the requirements for the system-to-be.
