Drowning can be divided into two categories: dry drowning and wet drowning.
Dry drowning refers to a person’s throat spasms caused by strong stimuli (panic, fear, sudden cold, etc.) after entering water, resulting in complete obstruction of the respiratory tract and suffocation death. When the throat spasms, the heart can reflexively stop beating, or it can be caused by asphyxia or myocardial hypoxia.
Wet drowning can be divided into freshwater drowning and seawater drowning based on the composition of the water during drowning. However, regardless of the composition of water, when inhaled by a drowning person, it may cause harm to the human body and even endanger life through certain actions.
Regardless of the cause of drowning, it can cause systemic hypoxia and can lead to cerebral edema.
Inhalation of sewage into the respiratory tract can lead to pulmonary infections. The worsening of the condition can lead to complications such as acute respiratory distress syndrome, disseminated intravascular coagulation, and acute renal failure. Therefore, correct first aid in the event of drowning is crucial for saving the lives of drowning victims.
