Did Lisa die in 47 meters down?
47 Meters Down had set up this reveal when Taylor had warned switching tanks increased the danger of “nitrogen narcosis,” which led to Lisa’s vivid hallucination of saving Kate. Lisa is eventually saved by divers and is taken back to the boat, and comes to accept her sister was killed by the shark.

What is crush depth for a human?
In short: most of the body can handle any pressure, but if we’re breathing air the maximum safe depth is about 60 meters (190 feet), the feasible maximum with current technical capabilities (and special breathing gases) is about 500 meters (but, for safety reasons, those depths have only been simulated).
How deep can a human go underwater before being crushed?
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
Can you dive down to the Titanic?
An anniversary deep-sea diving expedition will offer tourists a chance to visit the R.M.S. Titanic, a hundred years after the legendary ship sank to the bottom of the frigid North Atlantic. … The trip to Titanic’s resting place takes about 2.5 hours, and a round-trip dive lasts about 8 to 10 hours.
Can water pressure kill you?
The pressure of the water on a deep-diver’s body can crush him. It can easily cause death. Coming up from the extreme pressure of deep water to the much lower pressure at the surface is especially dangerous. Ascending too quickly can cause a fatal condition called “the bends.”
What happens at 47 meters underwater?
At 47 meters down, a person is experiencing 5.67 atmospheres, which means they blaze through their air at nearly six times the rate they would at the surface.
How many meters underwater can a human survive?
Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.

What happens if you go too deep in the ocean?
As you descend, water pressure increases, and the volume of air in your body decreases. This can cause problems such as sinus pain or a ruptured eardrum. As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe.
At what depth do your lungs collapse?
If one descends to a depth of 100 feet (about 30 metres), the lung shrinks to about one-fourth its size at the surface. Excessive compression of the lungs in this manner causes tightness and pain in the thoracic cavity.
Did anyone survive in 47 meters down?
Well, there are actually two endings to 47 Meters Down. The first one is a fake-out, as Mandy Moore’s character hallucinates that she and her sister have been rescued. The actual ending, as we soon realize, is that Moore’s character survives, while her sister doesn’t make it out of the water alive.
