Medical emergencies have been the subject for inventors and researchers in finding better ways to deal with these emergencies. Every medical emergency is composed of three major elements: the call for help or in some cases emergency warnings, assessing the patient condition, and the provision of professional medical attention. Medical emergencies come in various forms and ranges. Medical emergencies can be broad like for instance a disease outbreak that cuts across states and countries. In this type of emergency it is important to warn the public of the medical emergency, to monitor and document patients who may have contracted the disease, and the efficient dispatch of medical help to those that need it. Medical emergencies can also be at the level of personal medical emergency wherein the emergency is limited only to particular individual.
For broad medical emergencies, the usual alert system in place in many countries is referred to as emergency population warning. It is composed of a system or a group of systems that relays information of the emergency (such as weather disturbances and disease outbreak) to the entire population. For this emergency broadcast system, it is also important to have an agreement on who can initiate the warning and the types of emergencies that will activate the warning system. In the US, this system is referred to as the Emergency Alert System (EAS). The alert system makes use of air raid sirens deployed in every community. Just recently, warning can also be distributed using short messaging system or text messages of mobile phones and through electronic mail.
At the level of personal medical emergencies, the most popular method of relaying personal medical emergencies is the use of medical alert devices some service providers call this also as medical alarm. These devices are worn by the subscribers as bracelets or pendants. These devices when activated by a subscriber will send a personal alert message to a remote base station, which will then assess the situation and facilitate the provision of needed medical services the subscriber calling for help. Others facilitate medical help in emergencies. These personal alert systems also include services such as prescription reminders, meal reminders and security alerts. Subscribers in return to the services they received will pay monthly or annual fees. These personal medical alert products are very popular among seniors who wished to live independently.
Another related field of emergency alerts during medical emergencies is the use of computer-aided dispatch (CAD) popularly known as the 911 services. The 911 services bring together the police, fire department and hospitals in order to centralize the provision of help during emergencies including medical emergencies. Citizens suffering or who have witnessed a medical emergency simply dial 911 on the phone, explain the emergency to the operator, and describe the location of the emergency so that the operator can dispatch nearby units of police, firefighters or emergency medical services. There have been researches made on the possibility of including electronic medical records of people into the EMS system in order to increase the accuracy of first responders in giving first treatment. In this system, the EMS personnel simply dial the CAD center, provide the person’s name and download the patients’ medical information in the form of audio or text.
