		With rebreathers, however, the breathing gas may be dynamic, and thus the oxygen concentration may drift out of life-sustaining range within the course of a single dive.
		In the case of oxygen rebreathers, if the breathing loop is not adequately flushed prior to commencing the dive, the fraction of nitrogen in the breathing gas may be high.
		For oxygen rebreathers with passive-addition oxygen control systems, it is possible that the diver may breathe-up all of the oxygen in the breathing loop before the oxygen addition valve is triggered, thus leaving only nitrogen.

	closed circuit rebreathers, parts and training
		We are a company who design and manufacture closed circuit rebreathers, parts and accessories with the focal point on simplicity, durability and user friendliness.
		Behind every rebreather part lies hundreds of hours of thinking, designing, prototyping, testing and diving.
		Non of this is intended to be used as reference or to replace a proper closed circuit rebreather training course.

	Halcyon: RB80 Rebreather System Configuration
		Since rebreathers inherently increase the risk of any dive, individuals should first consider whether their activity justifies the use of a rebreather at all.
		A rebreather is a device that captures and recirculates at least part of a diver's exhalation, thereby allowing the diver to rebreathe part of his previous breath.
		Therefore, a rebreather may be thought of as a gas extension device that simultaneously reduces bubble output.

		The hazard with this type of system on an oxygen rebreather is that it is vitally important to flush the breathing loop with pure oxygen prior to the commencement of the dive.
		In the case of oxygen rebreathers, if the breathing loop is not adequately flushed prior to commencing the dive, the fraction of nitrogen in the breathing gas may be high.
		For oxygen rebreathers with passive-addition oxygen control systems, it is possible that the diver may breathe-up all of the oxygen in the breathing loop before the oxygen addition valve is triggered, thus leaving only nitrogen.

	Rebreather - Scupedia
		A rebreathers whose counterlung is rubber and not in an enclosed casing, should be sheltered from sunlight when not in use, to prevent the rubber from perishing.
		The major task of the fully closed circuit rebreather is to control the oxygen concentration, known as the oxygen partial pressure, in the loop and to warn the diver if it is becoming dangerously low or high.
		A particular problem when using a closed circuit rebreather is the drop in ambient pressure caused by the ascent phase of the dive, which can reduce the partial pressure of oxygen to hypoxic levels leading to what is sometimes called shallow water flout.

		Whereas most semi-closed rebreathers maintain a (more or less) constant fraction of oxygen (FO) throughout the course of the dive, closed-circuit rebreathers maintain a relatively constant partial pressure of oxygen (PO) in the breathing loop.
		As mentioned above, semi-closed rebreathers maintain a more-or-less constant fraction of oxygen in the breathing gas, whereas closed-circuit rebreathers maintain a constant partial pressure of oxygen in the breathing gas.
		A closed-circuit rebreather maintains the concentration of oxygen in the breathing gas at it maximum safe value throughout the dive.

	what is a rebreather
		To understand what a rebreather is and how it works, it is useful to understand how conventional scuba works.
		The oxygen rebreather is the simplest kind of rebreather system, and will form a starting point for discussion of more complex systems.
		Another problem with active-addition semi-closed rebreathers is that the concentration of oxygen in the breathing loop is variable.

	Rebreather
		The Draeger Dolphin rebreather that I used is probably the simplest rebreather on the market, and is also by far the most popular for recreational diving.
		The rebreather is also much bulkier for travel, particularly since you generally need to take your own tanks since most dive shops/resorts don't have tanks of the right size or with the right fittings.
		Since the rebreather recycles the air you're breathing, you can continue to breath the same air in and out, completely depleting the oxygen in the air if there is no source to replenish the oxygen.

	Rebreather Training
		This means that instruction on a rebreather recognizes that each type of rebreather has its own characteristics and instructional/use differences.
		Quite frankly, one of the problems with the evolution of this industry from a manufacturer's standpoint is that you've got to sell or give a rebreather to an instructor and let that instructor use it for a year of so, before he or she starts offering units for sale and then training people.
		I would say the first hundred hours of diving that rebreather is a minimum requirement for anybody to teach rebreather diving.
