How do animals that dive deep avoid decompression sickness?
When dolphins dive deep below the water’s surface, they avoid succumbing to decompression sickness, or “the bends,” likely because the massive sea creatures have collapsible lungs, a new study finds. These lungs allow dolphins to inhale and exhale two to three times quicker than humans.
What are the bends What does this have to do with pressure can whales get the bends?
One of these is decompression sickness (DCS), also known as “the bends”. Under the high pressures experienced at depth, nitrogen can dissolve into the bloodstream (because gasses are more soluble at high pressures).
What are the bends and how can they be prevented?
Dehydration seems to be a major factor in DCS. Take a day off during a week of diving. By taking a day off midweek, you decrease your nitrogen loading and give your body an opportunity to recover. Increase surface intervals, and decrease no-decompression limits.
Can you fart while diving?
Farting is possible while scuba diving but not advisable because: … An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness. The acoustic wave of the underwater fart explosion can disorient your fellow divers.
Why do divers get the bends?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues.
Why are seals better divers than humans?
Elephant seals can dive further and stay under water much longer than humans. … As previously mentioned, one factor is that animals that dive well have higher oxygen stores than do humans.
Do seals have collapsible lungs?
In deep-diving whales and seals, the peripheral airways are reinforced, and it is postulated that this allows the lungs to collapse during travel to depth. Such collapse has been observed radiographically and confirmed with blood nitrogen analyses in the deep-diving Weddell seal.
