Buddy breathing is a rescue technique used in scuba diving "out-of-gas" emergencies, when two divers share one demand valve, alternately breathing from it.Techniques have been developed for buddy breathing from both twin-hose and single hose regulators, but to a large extent it has been superseded by safer and more reliable techniques using additional equipment, such as the use of a bailout ...
The diver should keep breathing constantly to maintain consistent gas flow at moderate flow velocities over the carbon dioxide absorbent, so the absorbent can work most effectively. Divers need to lose any skip-breathing habits that may have been developed while diving with open-circuit scuba. In closed circuit rebreathers, constant moderate ...
Buddy bottle – Alternative name for scuba bailout set; Buddy breathing – Technique for sharing breathing gas from a single mouthpiece; Buddy check – Pre-dive safety checks carried out by two-diver dive teams; Buddy diver – Person diving by the buddy system; Buddy diving – Practice of mutual monitoring and assistance between two divers
Scuba diving therapy is a type of treatment that consists of a variety of scuba diving activities and exercises. Essential elements are increased body awareness, social bonding, and breathing techniques. The goal is to improve physical and psychological well-being. [1]
The instructor monitors a trainee practicing diving skills. Scuba skills are skills required to dive safely using self-contained underwater breathing apparatus, known as a scuba set. Most of these skills are relevant to both open-circuit scuba and rebreather scuba, and many also apply to surface-supplied diving. Some scuba skills, which are ...
Rebreather diver with bailout and decompression cylinders. Scuba gas management is the aspect of scuba diving which includes the gas planning, blending, filling, analysing, marking, storage, and transportation of gas cylinders for a dive, the monitoring and switching of breathing gases during a dive, efficient and correct use of the gas, and the provision of emergency gas to another member of ...
The history of scuba diving is closely linked with the history of scuba equipment.By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon dioxide is filtered from ...
Hydrox, a gas mixture of hydrogen and oxygen, is occasionally used as an experimental breathing gas in very deep diving. [1] [2] It allows divers to descend several hundred metres. [3] [4] [5] Hydrox has been used experimentally in surface supplied, saturation, and scuba diving, both on open circuit and with closed circuit rebreathers. [6]
