Scuba diving has existed since the twentieth century. It is closely linked to the history of the scuba equipment. It basically began with the development of two architectures for the underwater breathing device, namely open and closely circuit apparatus. The open circuit surface supplied the equipment is where the diver exhaled gas gets vented into the water directly. It developed further by the introduction of demand regulators. When in need of Scuba Diving Cartagena should be visited.
The diving was later developed and it made it able for a diver to have enough supply of air. This was achieved by flow of air from the tank being adjusted as per the breathing pressure requirements of an individual. During that time the cylinder was not able to withstand high pressure therefore supply of air came from the surface.
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.
It has two gauges with one meant for pressure of the tank and another one meant for the supply pressure. The air is supplied continually to the mouth piece and then ejected via the short exhaust tube. The pipe has a valve that is used to regulate the air. Though so far it has really improved but still is under further development.
According to studies inventors are on the search of a way they can make scale down the whole system. The aim of this idea is to increase the valuable time of underwater breathing apparatus. Closed circuit and the open circuit apparatus were developed at around the same time. In this system the carbon dioxide gas the diver exhales is allowed to recirculate back after being filtered with unused oxygen.
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 bag contains sixty percent of oxygen supplied by a cooper tank and carbon (IV) Oxide scrubbed by a rope yarn soaked in a caustic solution. The system is also still under further development over time. The current model has really improved and can travel up to a thousand feet deep the ocean. It also has the ability to hold greater amounts of oxygen.
Divers engage in this activity for various reasons, including professional and personal reasons. People also take part in this activity for recreational purposes the same way they do cave diving or take part in deep sea diving. Divers can also be hired to undertake different underwater duties. The military can also utilize this technique for infiltration or direct combat.
