Editing Decompression sickness (section)

=== Decompression illness and dysbarism ===
The term [[dysbarism]] encompasses decompression sickness, [[arterial gas embolism]], and [[barotrauma]], whereas decompression sickness and arterial gas embolism are commonly classified together as [[decompression illness]] when a precise diagnosis cannot be made.{{sfn|Francis & Mitchell, ''Manifestations''|p=580}} DCS and arterial gas embolism are treated very similarly because they are both the result of gas bubbles in the body.{{r|Francis}} The U.S. Navy prescribes identical treatment for Type II DCS and arterial gas embolism.{{r|USNDM2008}} Their spectra of symptoms also overlap, although the symptoms from arterial gas embolism are generally more severe because they often arise from an [[infarction]] (blockage of blood supply and tissue death).
