When a diver descends to lower pressure than the ambient, it is called decompression. During ascent from depth, the diver’s body is compressed. This process can be dangerous but should be avoided if decompression diving done properly. Read more about decompression dive and decompression sick. Also read about decompression sickness penalties and standard treatment. Below are some questions that decompression divers might ask.
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. You can use a V planner if you want to do a dive below 35m. If not, you can calculate deco manually.
The minimum deco is half of the average depth and a slow ascent. The name is misleading because it takes more than a minute. The average time it takes to ascend 10ft/3m is 30 seconds. After that, you stop for 30 seconds and then recover 30 seconds before starting again. Before you begin to ascend, make sure your air has been fully decompressed. The best way is to make sure you have enough gas in the tank.
Planned diving
A computer-generated plan that allows for decompression diving is a great tool 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 break is a series stop during ascent to allow the body's ability to expel helium and nitrogen. To adjust to the pressure of the surrounding environment, a lengthy decompression break is required. The depth attained and the profile of a diver determine the duration of decompression stops. Planning multiple stops is important if you wish to travel to the depths of the ocean.
Standard treatment for decompression sick
To prevent decompression sickness, a standard treatment is to inhale 100% oxygen through a mask. 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.
For acute cases, the diver should receive supplemental oxygen until assistance arrives. Decompression sickness may be difficult to diagnose, since symptoms may not be immediately apparent. The diver should be treated immediately and kept warm until assistance arrives. You should monitor your diver's condition closely and rule out any neurological signs. If symptoms aren't visible after a few minutes, they could be indicative of air embolism.
Penalties for decompression diving
Penalties can be imposed for decompression diving. This could lead to consciousness loss and insufficient oxygen supply to the lungs. These consequences can be avoided and decompression illnesses reduced by using a variety of methods. Know what you are doing while diving. 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. In recreational diving, the NDLs and depth limits are largely concerned with fast tissues. Maximum ascent rates are set to allow for the direct ascent from the surface. Regardless of the type of tank, decompression diving requires more complex calculations. Buhlmann ZH-16 algorithms fixes nitrogen at halftimes 2.65 times longer that helium's. If the helium fractions are higher than expected, it will add an increasing time to decompression.
