The aqualung works using a “regulator”, or “demand valve”. It lets a person breathe in and out through the same mouthpiece. The regulator connects to tanks of compressed air, and these attach to a vest the person can wear.
Who would use an aqualung?
A piece of equipment consisting of an oxygen tank and breathing apparatus used by divers to allow them to breathe underwater at depth. Etymology: Aqualung was the original name for the first open-circuit SCUBA diving equipment by Emile Gagnan and Jacques Cousteau in 1943. To scuba dive.
How does a scuba system work?
A scuba includes metal tanks which hold compressed air (or a special mix of breathing gases), a regulator to reduce the tank air pressure to breathable air, and a hose that carries the breathable air into the diver’s mouth. When a diver exhales, air is released into the water and creates little bubbles.
What do you think would be an aqualung?
The word “aqualung” was commonly used in speech and in publications as a term for an open-circuit, demand valve-controlled breathing apparatus (even after Air Liquide’s patent expired and other manufacturers started making identical equipment), occasionally also for rebreathers, and in figurative uses (such as “the …
What happens to your lungs when you dive?
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. If air bubbles get into an artery, they can cause a blockage that affects your organs. The blockage is called an arterial gas embolism.
Who invented the aqualung to breathe underwater?
1943. French naval officer Jacques-Yves Cousteau and Air Liquide engineer Emile Gagnan develop an autonomous diving system with a demand regulator, the scaphandre autonome. It would soon be called “Aqua-Lung,” after Cousteau coined the word for English-speaking countries.
What is the meaning of Aqualung?

Is scuba diving healthy?
Fighting currents, swimming around reefs and powering back to the boat are just a few of the exercises that scientists say improve our cardiovascular health and allow us to burn up to 500 calories per hour when scuba diving. … Those who dive regularly will see the benefit of both increased muscle mass and less body fat.
Why is scuba diving dangerous?
Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.
What does it feel like to scuba dive?
The very first feeling you experience while SCUBA diving is the absolute freedom. You are freed from gravity. You feel weightless as if you are flying. After the first few SCUBA dives, you realize that you resemble more of an astronaut who is exploring a whole new planet.
How does a Turbosail work?
An aspiration system pulls air into the tubes, and is used to increase the depression on one side of the sail; a reaction force occurs as the result of the pressure difference. In this way, the sails act as wings, creating both lift and drag.
Where is Aqualung made?
Aqua Lung America (formerly U.S. Divers Company) is an American company based in Vista, California which makes scuba equipment.
Who invented diving chamber?
This chamber was used to treat “nervous and related disorders.” The first decompression chamber was invented by the Italian engineer Alberto Gianni in 1916 [39, 40]. In 1928, the Harvard Medical School built a hyperbaric chamber for medical research.
How deep can a human dive before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
Can your lungs explode scuba diving?
One of the most important rules in scuba diving is to breathe continuously and never hold your breath. … If you ascend while holding your breath, your lungs could expand (“explode”) as the air expands. This is known as a pulmonary barotrauma.
What happens to your body if you dive too deep?
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.
