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. Factors affecting probability of long term recovery with mild deficits or full function in young children include the duration of submersion, whether advanced life support was needed at the accident site, the duration of cardiopulmonary resuscitation, and whether spontaneous breathing. If not breathing, rescue ventilation is necessary. 30 During drowning, aspirated water enters the lung tissues, causes a reduction in alveolar surfactant, obstructs ventilation and triggers a release of inflammatory mediators which ultimately results in hypoxia.

Physiology of Breath-hold Diving. 7 In those whose heart is not beating and who have been underwater for less than an hour CPR is recommended. 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 WHO further recommended that outcomes should be classified as: death, morbidity, and no morbidity. "Field Management of Accidental Hypothermia during Diving". "Wilderness Medical Society Practice Guidelines for the Prevention and Treatment of Drowning". Citation needed After a successful approach, negatively buoyant objects such as a weight belt are removed. 32 Cold water immersion edit Submerging the face in water cooler than about 21 C (70 F) triggers the diving reflex, common to air-breathing vertebrates, especially marine mammals such as whales and seals. Neurological examination at the time of discharge from hospital does not accurately predict long term outcomes. A b Staff (23 September 2014). A b Idris, AH (2003). The Alliance for Safe Children.
