Decompression is when a diver descends below the ambient pressure. During ascent, the body of a diver is subject to decompression. This can be dangerous and should not be done if decompression diving has been done correctly. Read more about decompression dive and decompression sick. Learn more about decompression illness penalties and standard treatment. These are some of the most common questions a decompression diver might have.
Deco dives
When planning a deco dive, you'll want to run through the basic program in your V-planner. You can then see how much deco you need to get the right visibility and depth. A V-planner can be used to plan a dive up to 35m. Otherwise, deco will have to be calculated manually if you are able.
A minimum deco means a slow ascent starting at half the 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. You may want to make sure that you've decompressed fully before attempting to ascend. To do this, ensure you have enough oxygen in your tank.
Planned diving
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. Divers can create dive plans using this software. They can choose a decompression period, OTU and CNS loadings, and the gas requirements for each depth. Divers can use the PC planning software to avoid common mistakes made when planning a dive manually.
A decompression stop is a series of stops during an ascent in order to allow the body to expel nitrogen and helium. To adjust to the environment's pressure, a long decompression stop will be necessary. The depth attained and the profile of a diver determine the duration of decompression stops. Plan multiple decompression stops if you plan to reach the deepest depths.
Standard treatment for decompression illness
Decompression sickness is treated by inhaling 100% oxygen through a mask and maintaining blood pressure. Fluids are administered to prevent oxygen loss. To reverse blood pressure changes, and to turn nitrogen back into liquid form, intensive treatment is done. This can take several hours. If decompression sickness is severe, you should avoid diving until the symptoms subside.
Supplemental oxygen should be given to the diver in acute cases. Sometimes, decompression sickness can be hard to diagnose because symptoms may not appear immediately. Nonetheless, the diver should receive emergency care and be kept warm until help arrives. The condition of the diver must be monitored closely. Any neurological signs should be ruled out. They could be signs of an air embolism, if symptoms do not appear within a few seconds.
Penalties for decompression diving
Decompression diving penalties can lead to loss of consciousness or insufficient air supply to your lungs. Fortunately, there are many methods to avoid these consequences and to reduce the risk of decompression illness. 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.
You should not underestimate the decompression period. This is the first mistake that you need to avoid. Recreational diving's NDLs or depth limits are more concerned with fast tissues. Maximum ascent rates should allow for direct ascent to surface. It doesn't matter what type of tank it is, decompression diving involves more complex calculations. Buhlmann ZH–L16 fixes nitrogen half-times at 2.65x more than helium. In addition, it adds a longer time for decompression if helium is higher than anticipated.
