Drowning is a type of suffocation induced by the submersion of the mouth and nose in a liquid. Submersion injury refers to both drowning and near-miss incident. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance.
The air may then enter the arterial circulation producing arterial gas embolism (AGE), with effects similar to severe decompression sickness. [7] Although AGE may occur as a result of other causes, it is most often secondary to PBT. AGE is the second most common cause of death while diving (drowning being the most common stated cause of death ...
Exudation of liquid into the lungs (pulmonary edema) over the hours following aspiration of liquid, which reduces the ability to exchange air and can lead to a person "drowning in their own body fluid". Aspiration of vomit can have a similar effect. Prompt and appropriate medical treatment after near drowning, including a medical observation ...
Unintentional drowning deaths have been rising for years, with 2023 the deadliest for kids. ... Experts and swim instructors agree the pandemic had an effect on the number of deaths as people were ...
Dry drowning has similar causes, but in this case, the water never reaches the lungs. It affects the vocal chords and causes spasms, shutting off the airways from oxygen. Victims of dry drowning ...
Drowning rates increased almost 30% in this age group in 2021 and 2022. Although the number of drowning deaths in children ages 4 and younger increased among young children in 2020, the rate ...
Oxygen toxicity is a catastrophic hazard in scuba diving, because a seizure results in high risk of death by drowning. [40] [73] The seizure may occur suddenly and with no warning symptoms. [19] The effects are sudden convulsions and unconsciousness, during which victims can lose their regulator and drown.
Cold water induced rhythm disturbances are common, albeit frequently asymptomatic. In most humans, head-out cold-water immersion results in sympathetically driven tachycardia with variable disturbances. These cold water immersion induced arrhythmias appear to be accentuated by parasympathetic stimulation resulting from facial submersion or ...
