A diver's body experiences decompression when it descends to a pressure lower than the ambient. During ascent from depth, the diver’s body is compressed. If decompression diving is done correctly, this can cause serious injuries. For more information, read about decompression diving and decompression sickness. Find out more about the decompression sick penalties and standard treatment. These are some of the most common questions a decompression diver might have.
Deco dives
To plan a deco diving trip, it is important to first go through the basic program on your V-planner. By doing so, you'll be able see how much is necessary to achieve the correct visibility. You can use a V planner if you want to do a dive below 35m. Otherwise, deco will have to be calculated manually if you are able.
Minimum deco refers to a slow ascent at half the average depth. The name is misleading because it takes more than a minute. In most cases, you will climb 10ft/3m in 30 second increments. Then, stop and rest for 30 seconds before continuing the process. Before ascending, you may need to ensure your tank is fully empty. To do this, ensure you have enough oxygen in your tank.
Planned dives
Divers can use a computer-generated plan to decompression dive. 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. Divers will be able to avoid the common mathematical errors that can occur when planning a diving trip manually by using the PC planner tool.
A decompression stop, which is a series or stops made during ascent, allows the body to expel nitrogen/helium. To adjust to the environment's pressure, a long decompression stop will be necessary. The maximum depth and profile of the diver will determine the length of the stop. Plan multiple decompression stops if you plan to reach the deepest depths.
Standard treatment for decompression illness
Standard treatment for decompression sick involves inhaling 100% oxygen through an oxygen mask, maintaining blood pressure, administering fluids to stop oxygen loss, and keeping the blood pressure constant. A hyperbaric oxygen chamber is used to reverse blood pressure changes and turn nitrogen into liquid. The body can then clear the matter in a matter of hours. If decompression sickness is severe, you should avoid diving until the symptoms subside.
Acute cases require that the diver receive supplemental oxygen. This should be continued until help arrives. It is possible to diagnose decompression illness, but symptoms may not be apparent immediately. However, emergency care should be given to the diver and they should be kept warm until help arrives. The diver's condition should be carefully monitored and any neurological signs must be ruled out. Air embolism is possible if symptoms persist beyond a few minutes.
Penalties for decompression diving
Penalties for decompression diving can result in the loss of consciousness and insufficient air supply to the lungs. Fortunately, there are many methods to avoid these consequences and to reduce the risk of decompression illness. While diving, make sure you know what you're doing. Without the right equipment, diving can cause decompression sickness. 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, NDLs (and depth limits) are mostly concerned about fast tissues. Maximum ascent rates are set to allow for the direct ascent from the 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.
