Acute onset of breathing problems caused by fluid accumulation in lung extravascular spaces induced by immersion, usually in cold water, often with intense physical exertion. Symptoms reported developed during physical activity and usually include dyspnoea/shortness of breath and a cough, often haemoptysis, occasionally chest tightness, chest ...
Respiratory risks of indoor swimming pools can include coughing, wheezing, aggravated asthma, [1] and airway hyper-responsiveness (spasms of the bronchial tubes in the lungs causing coughing and chest tightness). The chemicals used for pool water disinfection can react with organic compounds in the water to create disinfection by-products or
Divers must avoid injuries caused by changes in pressure. The weight of the water column above the diver causes an increase in pressure in proportion to depth, in the same way that the weight of the column of atmospheric air above the surface causes a pressure of 101.3 kPa (14.7 pounds-force per square inch) at sea level.
Exposure to cold water during a dive, and cold environment before or after a dive, wind chill. [46] Hypothermia: Reduced core temperature, shivering, loss of strength, reduced level of consciousness, loss of consciousness, and eventually death. Loss of body heat to the water or other surroundings. Water carries heat away far more effectively ...
The “wild swimming” trend — aka open-water swimming, or taking dips in lakes, rivers, streams or even the sea — isn't exactly new. Still, it has been increasing in popularity over the past ...
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.
Absent a clear answer as to why open-water swimmers might be at greater risk, Schmidt emphasized the need for more support for lifeguards, advance planning for emergencies at swimming events, and ...
Work of breathing is increased by increased density of the breathing gas, artifacts of the breathing apparatus, and hydrostatic pressure variations due to posture in the water. The underwater environment also affects sensory input, which can impact on safety and the ability to function effectively at depth.
