Decompression happens when a diver descends at a lower pressure that the ambient. During ascent from depth, the diver’s body is compressed. This process can be dangerous but should be avoided if decompression diving done properly. You can read more about decompression diving or decompression syndrome. Learn more about decompression illness 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. This will allow you to see the amount of deco required to reach the desired visibility and depth. A V-planner is useful if you're diving to 35m. Otherwise, deco will have to be calculated manually if you are able.
A minimum deco is a slow ascent from half the average depth. Its name is misleading, as it takes far longer than a minute. Usually, you'll ascend 10ft/3m in 30 seconds, stopping and recovering for 30 seconds before repeating the process. Before you attempt to climb, it is a good idea to ensure that your body has fully decompressed. You can do this by making sure that there is enough air in your tank.
Planned dives
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. 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 halt is a series stops that are made during ascent. It allows the body to expend nitrogen and helium. It is important to adjust the environment to the pressure. The maximum depth and profile of the diver will determine the length of the stop. If you want to go to the deepest depths, plan several decompression stops.
Treatment for decompression sickness
The standard treatment for decompression illness is to breathe 100% oxygen through the mask, maintain blood pressure and administer fluids to prevent oxygen from being lost. The intensive treatment involves using a hyperbaric oxygen chamber in order to reverse changes in blood pressure. This will turn nitrogen back into liquid, which can be cleared over several hours. Avoid diving if you feel decompression sickness.
For acute cases, the diver should receive supplemental oxygen until assistance arrives. Since symptoms might not be obvious immediately, it can be difficult to diagnose decompression syndrome. However, decompression sickness should be treated as an emergency and the diver should be kept warm until medical assistance arrives. The diver's condition should be carefully monitored and any neurological signs must be ruled out. They could be signs of an air embolism, if symptoms do not appear within a few seconds.
Penalties for decompression diving
Penalties can be imposed for decompression diving. This could lead to consciousness loss and insufficient oxygen supply to the lungs. There are many options to prevent these issues and minimize the risk of suffering from decompression. Be sure to know your limits when diving. Diving without the right equipment can lead to decompression sickness. Avoid these common mistakes when diving.
Avoiding the mistake of underestimating the decompression is the first. The NDLs and depth limits in recreational diving are mostly concerned with fast tissues. Maximum ascent rates are designed to allow the direct ascent to the surface. No matter what tank you have, decompression diving requires complex calculations. The Buhlmann ZH-L16 algorithm fixes nitrogen halftimes at 2.65 times longer than helium's, and it adds an increasing time for decompression if the helium fraction is higher than expected.
