Data expansion:

Drowning, also known as drowning, is a situation in which a person is submerged in water or other liquid media and is injured. Water fills the respiratory tract and alveoli causing hypoxic suffocation; water absorbed into the blood circulation causes changes in blood osmotic pressure, electrolyte disorders and tissue damage; ultimately causing respiratory arrest and cardiac arrest and death.

The consequences of drowning can be divided into non-morbid, morbid and fatal, and the process is continuous. Drowning occurs when the patient does not lose his life and is called near-drowning. A person who is suffocated and suffers from cardiac arrest after drowning is called death by drowning. If the heart does not stop, it is called near-drowning.

Within a few seconds after drowning, the human body instinctively holds its breath, causing the diving reflex (apnea, bradycardia and severe contraction of peripheral blood vessels) to ensure blood supply to the heart and brain.

Subsequently, hypercapnia and hypoxemia occur, stimulating the respiratory center and entering a non-spontaneous inspiratory period. As inspiratory water enters the respiratory tract and alveoli, the airways are filled, leading to severe hypoxia, Hypercapnia and metabolic acidosis. According to the nature of drowning, it is divided into freshwater drowning and seawater drowning.
