Scuba diving has been around since the 20th century. This activity is linked closely to the history line of the scuba equipment. It began by the development of two very important underwater apparatuses. The two were the closed circuit apparatus and the open circuit apparatus. In the open circuit apparatus the diver exhales the gas directly into water. The introduction of the demand regulator greatly boosted the development of this apparatus. When one needs Scuba Diving Cartagena offers the perfect location to visit.
This later followed by the development of a diving suit. The suit enabled a person to have a supply of air on their demand. This was made possible by just adjusting how the air flows from the tank so as to meet an individual breathing pressure needs. The air supply was mainly from the surface since at that time the cylinder could not withstand the necessary high pressures.
Air cylinders were developed in the early nineties. This enabled divers freedom to move around and explore the underwater. Nowadays the open circuit consists of a cylinder that has compressed air which the diver carries on their back. The compressed air is attached to some pressure regulator, which the diver can adjust manually.
The pressure regulator has two gauges one for supply pressure and another for tank pressure. Air is supplied continuously to a mouthpiece and expelled via a short exhaust pipe. The pipe has a valve which is used to control the air. Despite all these improvements the equipment is still being developed further.
Studies indicate that the inventors are still looking for a way to miniaturize the whole system. This is of course in order to improve the useful time of underwater breathing apparatus. Closed circuit apparatus was developed roughly at the same time as the open circuit. This system allows for the recirculation of the carbon dioxide after it has been filtered with unused oxygen. The carbon dioxide exhaled by the diver id filtered with unused oxygen and then recirculated back.
People use a little amount of oxygen when underwater as revealed by research. Oxygen is reduced by the recirculation. The system is designed with a rebreather for recycling the exhaled gas while simultaneously refilling it from the supply tank. This way oxygen is never depleted as the supply of air is kept constant. The first design was a prototype with a rubber mask fastened onto a breathing bag.
The content of the bag are 60 percent oxygen which is supplied from a cooper tank and carbon (IV) Oxide which is scrubbed by a rope yarn dipped in a caustic solution. However, this system is undergoing further development. Today, the model being used is quite improved and is capable of travelling thousands of feet deep down the ocean. Also, it holds large amounts of oxygen.
Scuba diving is performed for various purposes both personal and professional. It is done for recreational and enjoyment such as cave diving and deep sea diving. Divers are also employed to perform some underwater tasks. It is also utilized by the military for direct combat and infiltration.
