How much atmospheric pressure can the human body take?

The atmospheric pressure the body can take is about 2 to 3 standards. However, the human body can survive a range of atmospheric pressure. When there is sufficient oxygen available, you can breathe around 12.2 percent sea level of air pressure. When you are going down a dept of 100 feet or more, you can easily get crushed because every 33 feet of water depth, there is only one-atmosphere pressure available.

Deep-sea divers usually put themselves under extreme atmospheric pressure. Extreme atmospheric pressure has bad consequences, which include bone death and can lead to the life-shortening of such divers.

The amount of atmospheric pressure that the human body can survive in can vary on what is available. When there is oxygen available, the correct answer is about 12.2%. A human is able to still breathe at this percent level.

If there are extremer conditions in the atmosphere such as 1 is harder for the everyday human to be able to breathe at. However, people who are trained as deep see divers are able survive at this state, if not even more extreme.

Humans should not put themselves through such extremes, as there could be bone death. It could stress the body and ultimately shorten a person's life.

Atmospheric pressure is also known as barometric pressure, and it is the pressure within the atmosphere of the earth. The amount of atmospheric pressure a human body can take depends on what the person might be doing. Divers tend to maintain increasing pressure as they fall, which can limit how deep you can go.

If the diver breathes the natural air, nitrogen’s narcotic effects restrict divers up to six times more than the average atmospheric pressure. When you involve helium as opposed to nitrogen, it can help divers achieve 100 meters deep. Without the helium, the divers are kept from exploring greater depths than using nitrogen.

The human body can only take a certain amount of pressure. When the atmospheric pressure increases, this also decreases the amount of oxygen that will become available to human beings. This explains why some people would have a hard time breathing when they are on top of tall mountains. The atmospheric pressure there is greater and there will not be as much oxygen as compared to being on the lowlands.

When the amount of oxygen becomes too low, people will begin to exhibit some signs of sickness and may eventually die especially if they become exposed to low oxygen for a long period of time. The maximum amount that the human body can take will be 101kPa.

Humans survive a range of atmospheric pressures. Provided there is pure oxygen available, a human can still breathe in around 12.2 % sea level air pressure. At the other extreme, the normal atmosphere which is referred to as 1 (atmosphere) is exceeded by deep sea divers to an amazing extent.

I believe the record is 33 atmospheres whereas 3 would stress most of us. However, there are long term bad consequences from putting yourself through extreme atmospheric pressure like deep sea divers sometimes do. Bone death can occur from such excessive stress and therefore shorten the life of such divers.

By definition, standard sea-level pressure or atmospheric pressure is 14.70 pounds per square inch (psi). This can also be described as 1 standard atmosphere. The human body can withstand only 3 to 4 standard atmospheres. It is interesting to compare this to pressure in automobile tires which is about 2 standard atmospheres, or about 29 psi.

It is also interesting to note that for about every 33 feet of water depth, there is about one atmosphere of pressure so you can be crushed by going down to depths of around 100 feet or more.
