ELI5- Why is it dangerous for a scuba diver to ascend too quickly?
In: 19
Dissolved gasses in your blood emerge as bubbles from solution due to the effects of rapid decompression, which in turn is caused by too quick of a reduction in external pressure as you rise quickly from deep water to shallow water. Known as compression sickness or the bends. Just like when you open a carbonated beverage.
These gas bubbles can wreak havok on your lungs and venous systems through gas embolism and cause central nervous damage leading to paralysis, coma and even death.
