Drowning is defined as respiratory impairment as a result of being in or under a liquid. Drowning is more common when the weather is warm and among those with frequent access to water. Efforts to prevent drowning include teaching children to swim, safe boating practices, and limiting or removing access to water such as by fencing pools.
Inthere were an estimated 4. Drowning is erotische Geschichten Boy Prostata often quick and unspectacular. Its media depictions as a loud, violent struggle have much more in common with distressed non-swimmerswho may well drown but have not yet begun to do so. In particular, an asphyxiating person is seldom able to call for help. Drowning begins at the point a person is unable to keep their mouth above water; inhalation of water takes place at a later stage. A person drowning is generally unable to call for help, or seek attention, as they erotische Geschichten Boy Prostata obtain enough air.
The instinctive drowning response is the final set of autonomic reactions in the 20—60 seconds before sinking underwater, and to the untrained eye can look similar to calm safe behavior. Drownings in other erotische Geschichten Boy Prostata are rare, and often relate to industrial accidents.
Populations groups at risk: . Behavioral and physical factors:  . Drowning can be considered as going through four stages: . Generally, in the early stages of drowning a person holds their breath to prevent water from entering their lungs.
A conscious person will hold his or her breath see Apnea and will try to access air, often resulting in panicincluding rapid body movement. This uses up more oxygen in the blood stream and reduces the time to unconsciousness. The person can voluntarily hold his or her breath for some time, but the breathing reflex will increase until the person tries to breathe, even when submerged.
The breathing reflex in the human body is weakly related to the amount of oxygen in the blood but strongly related to the amount of carbon erotische Geschichten Boy Prostata see Hypercapnia.
During apnea, the erotische Geschichten Boy Prostata in the body is used by the cellsand excreted as carbon dioxide. Thus, the level of oxygen in the blood decreases, and the level of carbon dioxide increases. Increasing carbon dioxide levels lead to a stronger and stronger breathing reflex, up to the breath-hold breakpointat which the person can no longer voluntarily hold his or her breath.
The breath-hold break point can be suppressed or delayed either intentionally or unintentionally. Hyperventilation before any dive, deep or shallow, flushes out carbon dioxide in the blood resulting in a dive commencing with an abnormally low carbon dioxide level; a potentially dangerous erotische Geschichten Boy Prostata known as hypocapnia. The level of carbon dioxide in the blood after hyperventilation may then be insufficient to trigger the breathing reflex later in the dive and a blackout may occur without warning and before the diver feels any urgent need to breathe.
This can occur at any depth and is common in distance breath-hold divers in swimming pools. Hyperventilation is often used by both deep and distance free-divers to flush out carbon dioxide from the lungs to suppress the breathing reflex for longer.
It is important not to mistake this for an attempt to increase the body's oxygen store. The body at rest is fully oxygenated by normal breathing and cannot take on any more. Breath holding in water should always be supervised by a second person, as by hyperventilating, one increases the risk of shallow water blackout because insufficient carbon dioxide levels in the blood fail to trigger the breathing reflex.
A continued lack of oxygen in the brain, hypoxiawill quickly render a person unconscious usually around a blood partial pressure of oxygen of 25—30 mmHg. Artificial respiration is also much more effective without water in the lungs.
At this point the person stands a good chance of recovery if attended to within minutes. The lack of water found in erotische Geschichten Boy Prostata during autopsy does not necessarily mean there was no water at the time of drowning, as small amounts of freshwater are readily absorbed into the bloodstream.
Erotische Geschichten Boy Prostata and hypoxia both contribute to laryngeal relaxation, after which the airway is effectively open through the trachea. There is also bronchospasm and mucous production in the bronchi associated with laryngospasm, and these may prevent water entry at terminal relaxation. The hypoxemia and acidosis caused by asphyxia in drowning affect various organs. There can be central nervous system damage, cardiac arhythmias, pulmonary injury, reperfusion injury, and multiple-organ secondary injury with prolonged tissue hypoxia.
A lack of oxygen erotische Geschichten Boy Prostata chemical changes in the lungs may cause the heart to stop beating. This cardiac arrest stops the flow of blood and thus stops the transport of oxygen to the brain. Cardiac arrest used to be the traditional point of death but at this point there is still a chance of recovery. The brain cannot survive long without oxygen and the continued lack of oxygen in the blood combined with the cardiac arrest will lead to the deterioration of brain cells causing first brain damage and eventually brain death from which recovery is generally considered impossible.
The brain will die after approximately six minutes without oxygen at normal body temperature, but hypothermia of the central nervous system may prolong this. The extent erotische Geschichten Boy Prostata central nervous system injury to a large extent determines the survival and long term consequences of drowning, In the case of children, most survivors are found within 2 minutes of immersion, and most fatalities are found after 10 minutes or more.
If water enters the erotische Geschichten Boy Prostata of a conscious person, the person will try to cough up the water or swallow it, often inhaling more water involuntarily. When water enters the larynx or trachea, both conscious and unconscious persons experience laryngospasmin which the vocal cords constrict, sealing the airway.
This prevents water from entering the lungs. Because of this laryngospasm, in the initial phase of drowning, water generally enters the stomach erotische Geschichten Boy Prostata very little water enters the lungs. Though laryngospasm prevents water from entering the lungs, it also interferes with breathing. In most persons, the laryngospasm relaxes some time after unconsciousness and water can then enter the lungs causing a "wet drowning". In forensic pathologywater in the lungs indicates that the person was still alive at the point of submersion.
Absence of water in the lungs may be either a dry drowning or indicates a death before submersion. Aspirated water that reaches the alveoli destroys the pulmonary surfactantwhich causes pulmonary oedema and decreased lung compliance which compromises oxygenation in affected parts of the lungs. This is associated with metabolic acidosis, and secondary fluid and electrolyte shifts. During alveolar fluid exchange, diatoms present in the water may pass through the alveolar wall into the capillaries to be carried to internal organs.
Presence of erotische Geschichten Boy Prostata diatoms may be diagnostic of drowning. Of people who have survived drowning, almost one third erotische Geschichten Boy Prostata experience complications such as acute lung injury ALI or acute respiratory distress syndrome ARDS.
Whether a person drowns in fresh water versus salt water makes no difference in the respiratory management or the outcome of the person. This reflex protects the body by putting it into energy saving mode to maximize the time it can stay under water.
The strength of this reflex is greater in colder water and has three principal effects: [ citation needed ]. The reflex action erotische Geschichten Boy Prostata automatic and allows both a conscious and an unconscious person to survive longer without oxygen under water than in a comparable situation on dry land. The exact mechanism for this effect has been debated and may be a result of brain cooling similar to the protective effects seen in people who are treated with deep hypothermia.
The actual cause of death in cold or very cold water is usually lethal bodily reactions to increased heat loss and to freezing water, rather than any loss of core body temperature.
Submersion into cold water can induce cardiac arrhythmias abnormal heart rates in healthy people, sometimes causing strong swimmers to drown.
Upon submersion into cold water, remaining calm and preventing loss of body heat is paramount. Hypothermia and also cardiac arrest present a erotische Geschichten Boy Prostata for survivors of immersion, erotische Geschichten Boy Prostata for survivors of exposure; in particular the risk increases if the survivor, feeling well again, tries to get up and move, not realizing their core body temperature is still very low and will take a long time to recover.
Most victims of cold-water drowning do not develop hypothermia quickly enough to decrease cerebral metabolism before ischemia and irreversible hypoxia occur.
The WHO further recommended that outcomes should be classified as: deathmorbidityand no morbidity. Forensic diagnosis of drowning is considered one of the most difficult in forensic medicine. External examination and autopsy findings are often non-specific, and the available laboratory tests are often inconclusive or controversial. The purpose of investigation is generally to distinguish erotische Geschichten Boy Prostata the death was due to erotische Geschichten Boy Prostata, or whether the body was immersed post mortem.
The mechanism in acute drowning is hypoxemia and irreversible cerebral anoxia due to submersion in liquid. Drowning would be considered as erotische Geschichten Boy Prostata possible cause of death when the body was erotische Geschichten Boy Prostata from a body of water, or in close proximity to a fluid which could plausibly have caused drowning, or when found with the head immersed in a fluid. A medical diagnosis of erotische Geschichten Boy Prostata by drowning is generally made after other possible causes of death have been excluded by means of a complete autopsy and toxicology tests.
Indications of drowning are seldom completely unambiguous, and may include bloody froth in the airway, water in the stomach, cerebral oedema and petrous or mastoid haemorrhage.
Some evidence of immersion may be unrelated to the cause of death, and lacerations and abrasions may have erotische Geschichten Boy Prostata before or after immersion or death. Diatoms should normally never be present in human tissue unless water was aspirated, and their presence in tissues such as bone marrow suggests drowning, however, they are present in soil and the atmosphere and samples may easily be contaminated.
An absence of diatoms does not rule out drowning, as they are not always present in water. Most autopsy findings relate to asphyxia and are not specific to drowning. The signs of drowning erotische Geschichten Boy Prostata degraded by decomposition. Large amounts of froth will be present around the mouth and nostrils and in the upper and lower airways in freshly drowned bodies.
The volume of froth is generally much greater in drowning than from other origins. Lung density may be higher than normal but normal weights are possible after cardiac arrest reflex or vaso-vagal reflex. The lungs may be over inflated and waterlogged, filling the thoracic cavity, and the surface may have a marbled appearance, with darker areas associated with collapsed alveoli interspersed with paler aerated erotische Geschichten Boy Prostata.
Fluid trapped in the lower airways may block the passive collapse that is normal after death. Haemorrhagic bullae of emphysema may be found. These are related to rupture of alveolar walls. These signs, while suggestive of drowning, are not conclusive. Most drowning is preventable. Many pools and designated bathing areas either have lifeguardsa pool safety camera system for local or remote monitoring, or computer-aided drowning detection. However, bystanders play an important role in drowning detection and either intervention or the notification of authorities by phone or alarm.
Lifeguards may be unaware of a drowning due erotische Geschichten Boy Prostata "failure to recognize the struggle, the intrusion of non-lifeguard duties upon lifeguards' primary task-preventive lifeguarding, and the distraction from surveillance duties". Pool alarms have poor evidence erotische Geschichten Boy Prostata any utility. Many people who are drowning manage to save themselves, or are assisted by bystanders or professional rescuers. The statistics are not as good for rescue by bystanders, but even there, a minority require CPR.
Rescue involves bringing the person's erotische Geschichten Boy Prostata and nose above the water surface. A drowning person may cling to the rescuer and try to pull himself out of the water, submerging the rescuer in the process.
Rescuers should avoid endangering themselves unnecessarily and where possible should provide assistance from a safe position, such as a boat, or by providing flotation or a means of towing from erotische Geschichten Boy Prostata distance. Where it is necessary to erotische Geschichten Boy Prostata a panicking person in deep erotische Geschichten Boy Prostata, it is advised that the rescuer approach with a buoyant object, or from behind, twisting the person's arm on the back to restrict movement.
