You are constantly under pressure. Waiting presses under on friend at all times at 14.5 pounds every square inch, additionally called one bar or one atmosphere. Human beings can withstand 3 to 4 environments of pressure, or 43.5 come 58 psi. Water weighs 64 pounds every cubic foot, or one environment per 33 feet the depth, and presses in from every sides. The ocean"s pressure can indeed crush you.

You are watching: How much pressure can a human withstand


One reason you couldn"t resist the press of the ocean"s depth without serious defense is the difference in volume in between pressurized air and pressurized water. Molecules in air room spread out -- you deserve to squish them together quite a bit without do the wait in a given room weigh very much more. Water doesn"t squish -- a cubic foot of fluid water always weighs 64 pounds, and also 64 pounds of fluid water constantly takes increase one cubic foot of space. Deep water would squeeze the wait in her body, particularly in her sinuses and also lungs. Since air is compressible, this spaces would eventually collapse.


Water press would ultimately crush your other soft tissues as your depth increased, yet you would die of two results of gas compression and expansion long prior to this happened. The an initial is nitrogen narcosis. Waiting is consisted of of various proportions of several various gasses. Scuba equipment lets human beings dive longer and also deeper by offering compressed wait under the same pressure as the bordering water to stop lung collapse. However, compressed wait has an ext of every component gas, consisting of nitrogen. Your body doesn"t usage nitrogen because that anything. Under common conditions, it"s merely exhaled. However when you breathe pressurized air, you"re breath much greater levels the nitrogen than normal. The extra nitrogen dissolves in the blood and interferes through normal nerve impulses. At depths beginning about 100 feet, it offers a feeling of euphoria or drunkenness. By 300 feet, it causes loss the consciousness and death.


You"ll challenge the second danger of overfill nitrogen as you rise earlier to the surface. All the gas in a diver"s blood is compressed by the bordering water. Together he rises, this gas expands. Climb must it is in slow and also controlled to allow gradual expansion, take trip to the lungs and also exhalation. If an ascent is also fast, nitrogen bubbles may type inside the diver"s capillaries and block blood flow. This causes terrible pain known as "the bends." that can likewise cause blindness, paralysis, organ impairment and death. Once gas in the lungs expands too fast, the can cause arterial gas embolism. This happens when the tiny air bag in the lungs, referred to as alveoli, burst, releasing gas bubbles into the bloodstream traveling to the brain. This bubbles can reason stroke-like symptoms and also death.

Deep-diving naval mammals have special adaptations to withstand sudden push changes. Depth dwellers have actually adaptations come live under constant pressure. Humans are tied by ours physiology and also technology. Previous depths of around 99 feet -- 4 atmospheres of pressure -- reinforced atmospheric suits are necessary. These allow the human being inside to suffer a single atmosphere of push up to depths of approximately 2000 feet. Expedition from about 2000 feet to the ocean"s best of 36,200 feet calls for special equipment, mostly unmanned. The challenges associated in getting down there average the ocean"s depths -- 60 per cent of Earth"s ecosystem -- room still largely unknown.
