Create a goal model diagram for the patient-monitoring system below:

Each patient in an emergency service is monitored by an analog device that measures factors such as pulse, temperature, blood pressure and skin resistence. The software monitors these factors on a periodic basis, customized to each patient, and keeps them in a database for patient history tracking. For each patient, safe ranges are specified for each factor. If a factor fails outside of a patient's safe range, the nurse's station is notified.
