There are three types of rebreathers available: open circuit, closed circuit and mixed circuit. They all have their advantages and disadvantages. This article will describe the most common types of rebreathers, and what to look at when choosing one. The last section will discuss which rebreathers are safe for marine life. Regardless of which one you choose, make sure that it is compatible with the environment you'll be in.
Semi-closed circuit Rebreathers
One might feel tempted to select a closed-circuit model if you are comparing semi-closed or closed circuit rebreathers. However, these two types of rebreathers are largely similar in principle, and the primary differences are in the way gas is delivered and mixed. You will need to consider your specific goals and needs before deciding whether you want a closed-circuit or semi-closed-circuit model.
Continuous-flow "mixture rebreathers"
While most continuous-flow rebreathers are used for long dives, the newest versions allow you to breathe with the same oxygen concentration as your ambient air. This enables the user to breathe more easily, while still being protected from bacterial contamination. The rebreathers are also more durable and reliable than ever before. They can be used safely and won't cause any irritation if they are properly maintained.
Purging oxygen rebreathers
A rebreather diver must use a source of oxygen to provide a constant flow of gas. A cylinder attached to the diver’s rebreather stores the source of gas. Pure oxygen, or liquid oxygen, increases the work of breathing. The rebreather diver must breathe in a mixture of both gases. There are two types of rebreathers. Both types have similar functions. These rebreathers differ in the volume of gas. The best way to prevent hypoxia is for divers to be familiar with both.
Rebreathers don't disturb marine life
Rebreathers are quiet and don't disrupt marine life. Rebreathers provide an underwater dive experience that is more pleasant than open-circuit, which has noisy valves and gushy air. Rebreathers are more comfortable than other equipment so your only concern should be how comfortable you will breathe.
Cost of rebreathers
Rebreathers are essential medical equipment for those in the military, law enforcement, and other high-risk situations. The industry has grown due to increasing awareness of the safety and cost-savings of rebreathers. Many people may not be able to afford the expensive devices. Here are some tips that can help reduce the cost associated with rebreathers. Continue reading to find more.
Safety concerns for divers using Rebreathers
Although safety concerns surrounding rebreathers may be rare, they are still a concern. Some studies show that rebreather diving can be up to 10 times riskier than open-circuit scuba. Rebreather diving actually causes fewer deaths than base jumping or skydiving. To reduce risk, rebreathers must be determined and consistent in following safety protocols.
