Drowning in the context of Epilepsy

Affusion is a method of baptism where water is poured on the head of the person being baptized. The word "affusion" comes from the Latin affusio, meaning "to pour on". Affusion is one of four methods of baptism used by Christians, which also include total or partial immersion baptism and aspersion or sprinkling.

Christian denominations which baptize by affusion do not deny the legitimacy of baptizing by submersion or immersion; rather, they consider that affusion is a sufficient, if not necessarily preferable, method of baptism. Affusion and aspersion tend to be practiced by Christian denominations that also practice infant baptism. This may be due to the practical difficulties and dangers of drowning and hypothermia associated with totally immersing an infant in cold water. However, most Eastern Christians (e.g. Eastern Orthodox) and some Catholics practice infant immersion. Amish, Old Order Mennonites, and Conservative Mennonites still practice baptism by pouring.

Waterboarding or controlled drowning is a form of torture in which water is poured over a cloth covering the face and breathing passages of an immobilized captive, causing the person to experience the sensation of drowning. In the most common method of waterboarding, the captive's face is covered with cloth or some other thin material and immobilized on their back at an incline of 10 to 20 degrees. Torturers pour water onto the face over the breathing passages, causing an almost immediate gag reflex and creating a drowning sensation for the captive. Normally, water is poured intermittently to prevent death; however, if the water is poured uninterruptedly it will lead to death by asphyxia. Waterboarding can cause extreme pain, damage to lungs, brain damage from oxygen deprivation, other physical injuries including broken bones due to struggling against restraints, and lasting psychological damage. Adverse physical effects can last for months, and psychological effects for years. The term "water board torture" appeared in press reports as early as 1976.

Waterboarding has been used in diverse places and at various points in history, including the Spanish and Flemish Inquisitions, by the United States military during the Philippine–American War, by Japanese and German officials during World War II, by the French in the Algerian War, by the U.S. during the Vietnam War and the war on terror, by the Pinochet regime in Chile, by the Khmer Rouge in Cambodia, by British security forces during the Troubles, and by South African police during the Apartheid era. Historically, waterboarding has been viewed as an especially severe form of torture.

A diving helmet is a rigid head enclosure with a breathing gas supply used in underwater diving. They are worn mainly by professional divers engaged in surface-supplied diving, though some models can be used with scuba equipment. The upper part of the helmet, known colloquially as the hat or bonnet, may be sealed directly to the diver using a neck dam, connected to a diving suit by a lower part, known as a breastplate, or corselet, depending on regional language preferences, or simply rest on the diver's shoulders, with an open bottom, for shallow water use.

The helmet isolates the diver's head from the water, allows the diver to see clearly underwater, provides the diver with breathing gas, protects the diver's head when doing heavy or dangerous work, and usually provides voice communications with the surface (and possibly other divers). If a helmeted diver becomes unconscious but is still breathing, most helmets will remain in place and continue to deliver breathing gas until the diver can be rescued. In contrast, the scuba regulator used by recreational divers must be held in the mouth by bite grips, and it can fall out of an unconscious diver's mouth and result in drowning.

A splash pad or spray pool is a recreation area, often in a public park, for water play that has little or no standing water. This is said to eliminate the need for lifeguards or other supervision, as there is little risk of drowning.

Typically there are ground nozzles that spray water upwards out of the splash pad's raindeck. There may also be other water features such as a rainbow (semicircular pipe shower), or mushroom- or tree-shaped showers. Some splash pads feature movable nozzles similar to those found on fire trucks to allow users to spray others. The showers and ground nozzles are often controlled by a hand activated-motion sensor, to run for limited time.

Life support comprises the treatments and techniques performed in an emergency in order to support life after the failure of one or more vital organs. Healthcare providers and emergency medical technicians are generally certified to perform basic and advanced life-support procedures; however, basic life support is sometimes provided at the scene of an emergency by family members or bystanders before emergency services arrive. In the case of cardiac injuries, cardiopulmonary resuscitation is initiated by bystanders or family members 25% of the time. Basic life-support techniques, such as performing CPR on a victim of cardiac arrest, can double or even triple that patient's chance of survival. Other types of basic life support include relief from choking (which can be done by using the Heimlich maneuver), staunching of bleeding by direct compression and elevation above the heart (and if necessary, pressure on arterial pressure points and the use of a manufactured or improvised tourniquet), first aid, and the use of an automated external defibrillator.

The purpose of basic life support (abbreviated BLS) is to save lives in a variety of different situations that require immediate attention. These situations can include, but are not limited to, cardiac arrest, stroke, drowning, choking, accidental injuries, violence, severe allergic reactions, burns, hypothermia, birth complications, drug addiction, and alcohol intoxication. The most common emergency that requires BLS is cerebral hypoxia, a shortage of oxygen to the brain due to heart or respiratory failure. A victim of cerebral hypoxia may die within 8–10 minutes without basic life-support procedures. BLS is the lowest level of emergency care, followed by advanced life support and critical care.

A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water. The device will keep the wearer afloat with their head and mouth above the surface – they do not have to swim or tread water in order to stay afloat and can even be unconscious.

PFDs are commonly worn on small watercraft or other locations where accidental entry into deep water may occur in order to provide immediate support for the wearer should they end up in the water. PFDs are also kept on large vessels for passengers to wear in an emergency in order to help them stay afloat should they be forced to enter the water or accidentally fall overboard during an evacuation. PFDs are commonly worn for swimming and other activities that require an individual to be in water. This is for reasons such as safety (to prevent the drowning of weak swimmers, swimmers in dangerous conditions or swimmers far from safety), to make swimming easier and less demanding, to allow someone who is unable to swim to safely enter water, or as assistance for activities such as water skiing.

Freediving blackout, breath-hold blackout, or apnea blackout is a class of hypoxic blackout, a loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold (freedive or dynamic apnea) dive, when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it. It can be provoked by hyperventilating just before a dive, or as a consequence of the pressure reduction on ascent, or a combination of these. Victims are often established practitioners of breath-hold diving, are fit, strong swimmers and have not experienced problems before. Blackout may also be referred to as a syncope or fainting.

Divers and swimmers who black out or grey out underwater during a dive will usually drown unless rescued and resuscitated within a short time. Freediving blackout has a high fatality rate, and mostly involves males younger than 40 years, but is generally avoidable. Risk cannot be quantified, but is clearly increased by any level of hyperventilation.

Water cure is a form of torture in which the victim is forced to drink large quantities of water in a short time, resulting in gastric distension, water intoxication, and possibly death.

Often the victim has the mouth forced or wedged open, the nose closed with pincers and a funnel or strip of cloth forced down the throat. The victim has to drink all the water (or other liquids) poured into the funnel to avoid drowning. The stomach fills until near bursting, swelling up in the process and is sometimes beaten until the victim vomits and the torture begins again.
