However, modern patient monitors and implemented risk management (including alarms) must be constructed in accordance to approved and current international standards IEC 6 and IEC 80001-1. Monitoring of vital functions and function of life-support devices is essential for critically ill patients, although real evidence based data are missing. In complex fields of work like aviation, mining, anesthesiology, and intensive care medicine - and here particularly with regard to monitoring of vital functions - alarms are ubiquitous and have been the subject of medical, technical, and psychological research for decades. Today, comparable systems are available that send warning-SMSs (Short Message Service) of nearing tsunamis to mobile phones. Warning fires provided a visual alert to enemy attacks, visible across long ranges and enabling an early reaction of armed forces. Some of the first documented alarms are watchmen on towers in the Middle Ages, who warned of fires or enemies by ringing bells. Alarms have existed ever since humans have lived in groups.
