We explain what an emergency is and what types of emergencies exist. Also, what is an emergency system.

What is an emergency?
An emergency is a urgent and totally unforeseen attention whether due to an accident or unexpected event. Depending on the area in which it is used, this word may have different meanings.
The term emergency is usually used by most people to conjecture a situation that got out of control and as a consequence, caused a disaster.
Currently, we can distinguish between different types of emergencies:
- Ecological emergency The ecological emergency refers to that scenario derived from human activity or natural phenomena that seriously modify its composition, entailing great danger to the various ecosystems. A clear example of an ecological emergency is global warming and the oil spill.
- Rural emergency An example is forest fires, since when such a layer of fire spreads over hectares and hectares of forest, it causes erosion of the vegetal layer, causing a great loss of salts and nutrients to the soil. Due to the high temperatures during the fire, the chemical and biological composition of the soil is modified, putting people who live near the forest and those who feed on it in serious danger.
- Health emergency It is that emergency that was caused by a pandemic or epidemic, such as Ebola.
- State of emergency This is decreed when something happens in a country that threatens the peace of the citizens. The state of emergency consists of depriving oneself of certain rights or activities. During 2008, several countries declared a state of emergency due to influenza A and its rapid spread in the various states.

medical emergencies

The emergency system will respond to the patient's situation and the elements possessed by the doctor or whoever provides emergency medical assistance. The attention will also be different depending on the place where the emergency is requested If it is performed in a hospital, we speak of a hospital emergency. On the other hand, if it is done on the street, for example, we refer to pre-hospital medicine.
Emergency medicine or emergentology is what acts on a medical emergency, an advanced disease, or something that threatens a person's life.
Hospitals and ambulances have services that are commonly called emergencies or emergency. Generally, when an accident occurs on public roads, the steps to follow are the following: first, the accident area is secured, trying not to have more victims. Then, the emergency system is activated, trying to receive prompt help from the public health system.
The next step to follow is assistance to victims affected by the accident. It is very important not to move them from their positions, as they could have fractures and this would negatively affect their health. If we have not received instructions on how to care for accident victims, we must stay out of the situation, letting the experts do their job.
When the patient has no breathing or their heartbeat is slow or practically non-existent, it is of utmost importance that they begin to make their nervous system function artificially until professional help arrives. This includes cardiovascular breathing, defibrillation and advanced life support.
