A medical emergency is an acute injury or illness that poses an immediate risk to a person’s life or long-term health. These emergencies may require assistance from another person, who should ideally be suitably qualified to do so, although some of these emergencies such as Cardiovascular(Heart), Respiratory, Gastrointestinal cannot be dealt with by the victim themselves. Dependent on the severity of the emergency, and the quality of any treatment given, it may require the involvement of multiple levels of care, from first aides to Emergency Medical Technicians and emergency physicians.
Any response to an emergency medical situation will depend strongly on the situation, the patient involved and availability of resources to help them. It will also vary depending on whether the emergency occurs whilst in hospital under medical care, or outside of medical care (for instance, in the street or alone at home).
