The process of decompression occurs when a diver descends to a lower pressure than the ambient one. During ascent from depth, the diver’s body is compressed. This can be dangerous, so it is important to do decompression dives correctly. Learn more about decompression and decompression sickness. Find out more about the decompression sick penalties and standard treatment. Below are some of the common questions that a decompression diver may have.
Deco dives
To plan a deco diving trip, it is important to first go through the basic program on your V-planner. You can then see how much deco you need to get the right visibility and depth. A V-planner is useful if you're diving to 35m. Otherwise, it's best to calculate the deco manually.
Minimum deco refers to a slow ascent at half the average depth. It is not as short-term as its name suggests, and takes far more time than one minute. You will usually ascend 10ft/3m in 30 secs, then stop and recover for 30 secs before you repeat the process. It is important to be fully decompressed before you try to ascend. It is important to ensure that you have enough air in the tank.
Planned divers
A computer-generated plan can be useful for divers. The computer generates deco schedules according to a diver's chosen number of gases, decompression models, and conservatism settings. This software allows divers to plan dives according to a specific decompression time, OTU and CNS loadings, as well as gas requirements at each depth. The PC planning tool allows divers to avoid making the same mistakes as when manually planning a dive.
A decompression stopping is a series if stops that occur during an ascent. This allows the body and its helium to escape. It is important to adjust the environment to the pressure. The length of the decompression stops depends on the profile of the diver and the maximum depth reached. Plan multiple decompression stops if you plan to reach the deepest depths.
Treatment for decompression sickness
A standard treatment for decompression sickness involves breathing 100% oxygen through a mask, maintaining blood pressure, and administering fluids to prevent the loss of oxygen. In intensive treatment, the hyperbaric oxygen chamber is used in order to reverse the blood pressure changes and convert nitrogen back into liquid. This can be done over several hours. Avoid diving if you feel decompression sickness.
In acute cases, supplemental oxygen is given to the diver and should be maintained until help arrives. Decompression sickness may be difficult to diagnose, since symptoms may not be immediately apparent. Nonetheless, the diver should receive emergency care and be kept warm until help arrives. It is important to monitor the diver's condition and rule out neurological signs. Air embolism is possible if symptoms persist beyond a few minutes.
Penalties for decompression diving
Decompression diving penalties can lead to loss of consciousness or insufficient air supply to your lungs. There are several ways to avoid these problems and reduce your risk of developing decompression sickness. Know what you are doing while diving. Decompression sickness can result from diving without the proper equipment. Here are a few common mistakes that you can avoid when diving.
Underestimating the decompression time is the first mistake you should avoid. Recreational diving is dominated by fast tissues. Maximum ascent rates allow direct ascent to the surface. Decompression diving is more complicated than any other tank. The Buhlmann ZH-16 algorithm fixes nitrogen for 2.65 times longer as helium. Additionally, it increases the time required to decompress helium if it is higher than expected.
