An emergency call is made if the patient is unresponsive.
If one red or two yellow triggers are present, then immediate action is taken.
If one yellow trigger is present then the patient is more closely monitored.
If a red trigger is scored 2 points and a yellow trigger 1, then a sum score >=2 indicates immediate action.
