Decompression sickness (DCS) patients address the disease process by dissolving air bubbles in the blood and tissues and diffusing excess nitrogen to oxygenate ischemic regions.

DCS divers have to travel further to decompression rooms since the number of rooms accessible for 24-hour emergency care countrywide is decreasing at an alarming rate.
