With the recent surge in popularity of triathlons and swimming in open water events there has been an increasing incidence of SIPE. It has been reported in scuba divers, [4] [5] apnea (breath hold) free-diving competitors, [6] combat swimmers, and triathletes. [2] [7] The causes are incompletely understood as of 2010.
It often results from faulty diving equipment or improper breathing techniques, allowing fine water droplets to reach the lower respiratory tract. The condition begins with a cough, followed by shortness of breath, chest discomfort or pain, shivering, fever and other systemic symptoms.
Chest X-ray has been used for many years to diagnose pulmonary edema due to its wide availability and relatively cheap cost. [4] A chest X-ray will show fluid in the alveolar walls, Kerley B lines , increased vascular shadowing in a classical batwing peri- hilum pattern, upper lobe diversion (biased blood flow to the superior parts instead of ...
The disorders are caused by breathing gas at the high pressures encountered at the depth of the water and divers will often breathe a gas mixture different from air to mitigate these effects. Nitrox , which contains more oxygen and less nitrogen , is commonly used as a breathing gas to reduce the risk of decompression sickness at recreational ...
Decompression sickness can occur after an exposure to increased pressure while breathing a gas with a metabolically inert component, then decompressing too fast for it to be harmlessly eliminated through respiration, or by decompression by an upward excursion from a condition of saturation by the inert breathing gas components, or by a ...
It can cause a range of potential symptoms, including chest pain that can feel like pressure, tightness, pain, squeezing, or aching, as well as fatigue, nausea, and shortness of breath. A heart ...

Dehydration due to the higher rate of water vapor lost from the lungs at higher altitudes may contribute to the symptoms of altitude sickness. [13] The rate of ascent, altitude attained, amount of physical activity at high altitude, as well as individual susceptibility, are contributing factors to the onset and severity of high-altitude illness.
