There are several types of rebreathers: closed circuit, open circuit, and "mixture" rebreathers. Each one has its pros and cons. This article will explain the most common rebreathers and what to look for when choosing a rebreather. The final section will explain which rebreathers don't disturb marine life. No matter which one you choose to use, ensure that it's compatible with the environment in which you will be operating.
Semi-closed circuit respirators
When comparing closed circuit and semi-closed circuit rebreather systems, one might be tempted to choose a closed-circuit model. While these two types of systems are similar in principle and have some similarities, the major differences are in how gas is delivered. 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"
Continuous-flow rebreathers tend to be used for extended dives. The newest models allow you to inhale with the same level of oxygen as your surrounding air. This allows users to breathe easier while being protected against bacterial contamination. Rebreathers also have a higher durability and reliability than ever before. As long as the rebreathers are used properly, they won't be able to inhale water.
Purging oxygen to rebreathers
For constant gas flow, the rebreather diver needs to have an oxygen source. The source of gas is stored in a cylinder that is attached to the diver's rebreather. Pure oxygen or liquid oxygen increases the work required to breathe. Rebreather divers must inhale a mixture of both gasses. There are two types. Active addition and passive rebreathers. Both types of rebreathers are similar. The only thing that makes these rebreathers different is the volume. A diver should be aware of both methods, as this is the most effective method of preventing hypoxia.
Rebreathers don't disturb marine life
Rebreathers have one major advantage: they don't interfere with marine life. Rebreathers offer underwater diving a quieter experience than open-circuit divers, which are noisy with gushy and clogged gas. Rebreathers are more comfortable than other equipment so your only concern should be how comfortable you will breathe.
Rebreathers costs
Rebreathers can be an important medical tool for anyone in the military, law enforcement or other high-risk environments. Rebreathers are becoming more popular due to the safety benefits and cost savings. The high costs of the devices could discourage some people from using them. Below are some ways to reduce the cost for rebreathers. Continue reading to find out more.
Safety concerns for divers using Rebreathers
Although safety concerns surrounding rebreathers may be rare, they are still a concern. Some studies have shown that open-circuit diving is more dangerous than rebreather dive. Rebreather diving is safer than base jumping and skydiving, with fewer fatalities. To minimize risk, rebreather users need to be committed and persistent in following the safety protocols.
