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 ...
There may be locking of the jaw, or stiffness in the jaw muscles and the joints, especially present upon waking. [19] There may also be incoordination, asymmetry or deviation of mandibular movement. [2] Noises from the joint during mandibular movement, which may be intermittent. [18]

Jaw pain Stress and grinding your teeth at night are both generally benign reasons behind why your jaw may be aching. But persistent jaw pain may also be a sign of an underlying health condition.
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 ...
Shortness of breath out of proportion to effort being expended. [2] [7] Rapid, heavy or uneven breathing, or uncontrollable coughing. [10] Crackles, rattling or ‘junky’ feelings deep in the chest associated with breathing effort – usually progressively worsening with increasing shortness of breath and may be cause for a panic attack [2] [7]
Freediving blackout, breath-hold blackout, [1] or apnea blackout is a class of hypoxic blackout, a loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold (freedive or dynamic apnea) dive, when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it.
If you’re feeling a sense of dread, have pale skin, your heart’s pounding really quickly, and you feel stiff, heavy, cold, or numb, then you’re likely stuck in a freeze response. #16 Middle ...
