DECOMPRESSION SICKNESS

Decompression sickness, also known as "the bends", is a condition that occurs when the human body is exposed to an environment of decreasing pressure, such as when ascending rapidly during scuba diving or when descending rapidly in an aircraft or when experiencing a decompression in an aircraft. Decompression sickness occurs due to the dissolved nitrogen in the blood coming out of solution and forming bubbles causing pain in the joints, tingling under the skin, shortness of breath and affecting the nervous system.

  • The risk of decompression sickness significantly rises for individuals who have recently scuba dived using compressed air before flying. Pilots and passengers should not fly for 12 hours following the scuba diving, or 24 hours if the depth of 30 ft is exceeded during scuba diving.
