The gas in a bubble will equilibrate with the surrounding tissues and will therefore contain water vapor, oxygen, and carbon dioxide, as well as the inert gas. Vascular bubbles appear to form at the venous end of capillaries and pass through the veins to the right side of the heart, and thereafter are circulated to the lungs. [73]
Dissolved inert gases such as nitrogen or helium can form bubbles in the blood and tissues of the diver if the partial pressures of the dissolved gases in the diver gets too high above the ambient pressure. These bubbles and products of injury caused by the bubbles can cause damage to tissues known as decompression sickness, or "the bends". The ...
Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
Possibility of venous gas bubbles shunting into arterial circulation and causing emboli Otherwise low-risk venous gas bubbles formed during decompression may shunt through PFO during anomalous pressure differential episode such as coughing, Valsalva manoeuver, or exertion while holding the breath. Screening for PFO for high risk divers
"He was just like, 'I just need you to breathe,'" she said. New soldiers struggle with phone addictions, communication.
The principle behind IWR treatment is the same as that behind the treatment of DCS in a recompression chamber: [2] [3] an increase in ambient pressure will reduce the volume of the bubbles allowing better blood transport downstream of the bubbles. If the casualty can breathe pure oxygen further improvements will occur because the increase in ...

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. [ 2 ] [ 8 ] [ 9 ] Some authors believe that SIPE may be the leading cause of death among recreational scuba divers, but there is insufficient evidence at ...
