Medical Services

Emergency medical services (abbreviated to the initialism "EMS" in some countries) are a branch ofemergency services dedicated to providing out-of-hospital acute medical care and/or transport to definitive care, to patients with illnesses and injuries which the patient, or the medical practitioner, believes constitutes a medical emergency.
Emergency medical services may also be locally known as: first aid squad, emergency squad, rescue squad, ambulance squad, ambulance service, ambulance corps or life squadgoal of most emergency

services is to either provide treatment to those in need of urgent medical care, with the goal of satisfactorily treating the malady, or arranging for timely removal of the patient to the next point of definitive care. This is most likely an emergency department at a hospital or another place where physicians are available. The term Emergency Medical Service evolved to reflect a change from a simple transportation system (ambulance service) to a system in which actual medical care occurred in addition to transportation. In some developing regions, the term is not used, or may be used inaccurately, since the service in question does not provide treatment to the patients, but only the provision of transport to the point of care.
In most places in the world, the EMS is summoned by members of the public (or other emergency services, businesses or authority) via an emergency telephone number which puts them in contact with a control facility, which will then dispatch a suitable resource to deal with the situation.
