A diver's body experiences decompression when it descends to a pressure lower than the ambient. During ascent from deep, the body of the diver undergoes 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. Also read about decompression sickness penalties and standard treatment. These are some of common questions that decompression divers may encounter.
Deco dives
You will need to go through the V-planner's basic program before you plan a deco dive. That way, you can see how much deco is required to achieve the correct visibility and depth. A V-planner can be used to plan a dive up to 35m. If not, you can calculate deco manually.
A minimum deco means a slow ascent starting at half the depth. The name of the minimum deco is misleading as it takes much longer than one minute. Usually, you'll ascend 10ft/3m in 30 seconds, stopping and recovering for 30 seconds before repeating the process. Before you begin to ascend, make sure your air has been fully decompressed. It is important to ensure that you have enough air in the tank.
Planned divers
A computer-generated decompression plan can be a useful tool for divers. The computer generates deco plans according to divers' choice of decompression models and gases. With this software, divers can plan dives for a particular decompression time, CNS and OTU loadings, and gas requirements for each level of depth. Divers can save themselves from making silly mistakes when planning a dive by using the PC planning tool.
A decompression stopping is a series if stops that occur during an ascent. This allows the body and its helium to escape. To adjust to the environment's pressure, a long decompression stop will be necessary. The profile of the diver as well as the maximum depth reached will affect the length of the decompression breaks. Planning multiple stops is important if you wish to travel to the depths of the ocean.
Standard treatment for decompression illness
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. Intensive treatment consists of using a hyperbaric oxygen chamber to reverse the changes in blood pressure and drive nitrogen back into liquid form, which the body can clear over hours. Divers should not dive if they are suffering from severe decompression sickness.
In acute cases, supplemental oxygen is given to the diver and should be maintained 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. You should monitor your diver's condition closely and rule out any neurological signs. If symptoms don't appear after a few moments, it could indicate air embolism.
Penalties for decompression diving
Decompression diving may result in loss of consciousness and inadequate air supply to the lung. There are many ways to avoid these complications and decrease the chance of getting decompression illness. While diving, make sure you know what you're doing. Diving without the right equipment can lead to decompression sickness. Here are a few common mistakes that you can avoid when diving.
It is important not to underestimate the time it takes to decompress. Recreational diving, NDLs (and depth limits) are mostly concerned about fast tissues. Maximum ascent rates allow direct ascent to the surface. No matter what tank you have, decompression diving requires 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.
