However, when you notice other symptoms (like pain, swelling, or bruising), seek help immediately. The popping sound can be the result of nitrogen bubbles in the fluid that lines the joint. This happens when tendons (tissue structures that connect muscles to bone) are moved over bony protrusions, and then quickly snap back into place. If a diver surfaces too fast, the excess nitrogen will come out rapidly as gas bubbles. Rashes that are red or marbled may occur. When you "crack" your knuckles, that popping sound may be coming from the compression of nitrogen bubbles in the spaces of the joints. The Bends is an illness that arises from the rapid release of nitrogen gas from the bloodstream and is caused by bubbles forming in the blood and other tissues when a diver ascends to the surface of the ocean too rapidly. Most cases of decompression sickness respond well to a single treatment with hyperbaric oxygen. The process actually has a scientific name, cavitation. Called the Bends, this condition can also cause injuries involving the nervous system. https://www.uhms.org/.

Most have symptoms within 6 hours, while some develop them within the first hour of surfacing from a dive. Now if the Pgas of N2 increases to 5 atm: \[ P_{N2}=\dfrac {C}{\dfrac {11.5 mL N_{2}/ L}{\ 1 atm}} \], \[ 5 atm=\dfrac {C}{\dfrac {11.5 mL N_{2}/ L}{\ 1 atm}} \].
