Consider a hospital ’ s patient monitoring system. Each patient is connected to electronic instruments monitoring blood pressure, heart rate, and ECG. These monitoring instruments issue a binary signal indicating a STABLE ( = 0) or UNSTABLE ( = 1) condition. The results of each of these instruments are OR ed together to form a signal called EMERGENCY.

The EMERGENCY signals for each of the rooms (one patient per room) are then OR ed together and sent to the nurse ’ s workstation. If any instrument on any patient indicates an UNSTABLE condition, the emergency alarm is sounded and the nurse is urgently directed to the appropriate patient. Write a pseudo - code specification for such a system (define a simple pseudo - code syntax yourself).
