Drowning is understood as that process that causes breathing problems or impediments that may be due to various causes, either by immersion or submersion in a certain liquid; This phenomenon can be described as a type of suffocation due to the great difficulty in breathing. According to the dictionary of the Spanish Royal Academy, drowning refers to the action and effect of drowning or drowning or simply to “drowning”. On several occasions this condition is generated thanks to certain respiratory problems due to the rapid acquisition of liquids within the respiratory tract; In these cases, the individual’s first instinct will be to hold their breath until they can no longer breathe and the liquid will be taken directly to the lungs, preventing the normal exchange of gas from taking place in said organs, which can result in death.

The invasion of water in the lungs or airways can cause a kind of apnea, because the so-called epiglottis is obstructed in order to protect the airways, making it impossible to breathe freely even if the head is kept out of the water; then the oxygen that remains in the body is depleted and what is known as hypoxemia or a great decrease in the pressure of oxygen in the blood occurs.

In the case of wet drowning, there are four drowning states, classified according to their severity, which are: aquatic stress, minor hypoxia, major hypoxia, and anoxic drowning. As for the most common symptoms are partial or complete loss of pulse and dilated pupils.

Drowning can also occur without the need for liquids, but in the same way it is the lack or absence of air, which is due to the obstruction of the airway by a foreign body; and in this case, to provide assistance to people with this type of drowning, the Heimlich maneuver can be used, a first aid procedure that helps unblock the respiratory tract.
