Related to 3 levels alarm sources, medical and nursing staff should have different response to deal with potential
dangerous, the detailed demands as follows:
1. High priority alarm: medical and nursing staff should response immediately.
2. Medium priority alarm: medical and nursing staff should response quickly.
3. Low priority alarm: medical and nursing staff should response as soon as possible.
NOTE: Some models may have only Medium and Low alarm priority because of the different configuration.
