Cardiac arrest used to be the traditional point of death but at this point there is still a chance of recovery. 57 The United Kingdom has 450 drownings per year, or 1 per 150,000, whereas in the United States, there are about 6,500 drownings yearly, around 1 per 50,000. 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 a distance. Thus, the level of oxygen in the blood decreases, and the level of carbon dioxide increases. Non-fatal drownings have been estimated as two to four times more frequent than fatal drownings. 43 Drowning in salt water can leave significantly different concentrations of sodium and chloride ions in the left and right chambers of the heart, but this will dissipate if the person survived for some time after the aspiration.

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. Hypercarbia and hypoxia both contribute to laryngeal relaxation, after which the airway is effectively open through the trachea. The breath-hold break point can be suppressed or delayed either intentionally or unintentionally. 46 First aid edit See also: Expired air resuscitation, Cardio-pulmonary resuscitation, Basic life support, and First aid The checks for responsiveness and breathing are carried out with the person horizontally supine.
