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 hazardous and is usually avoided when decompression diving is done properly. Read more about decompression dive and decompression sick. 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. This will allow you to see the amount of deco required to reach the desired visibility and depth. You can use a V planner if you want to do a dive below 35m. Otherwise, you'll need to calculate deco manually, if possible.
A minimum deco is a slow ascent from 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 you attempt to climb, it is a good idea to ensure that your body has fully decompressed. It is important to ensure that you have enough air in the tank.
Planned dives
A computer-generated plan for decompression diving can be a valuable tool for divers. The computer creates deco schedules based on divers' chosen number of gasses, decompression models, conservatism settings, and other parameters. 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. Using the PC planning tool, divers can avoid silly mathematical mistakes that are common when planning a dive manually.
A decompression break is a series stop during ascent to allow the body's ability to expel helium and nitrogen. It is necessary to adjust to pressure in the environment. The profile of the diver as well as the maximum depth reached will affect the length of the decompression breaks. Plan multiple decompression stops if you plan to reach the deepest depths.
Treatment for decompression sickness
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. To reverse blood pressure changes, and to turn nitrogen back into liquid form, intensive treatment is done. This can take several hours. Divers should not dive if they are suffering from severe decompression sickness.
In severe cases, oxygen supplementation is administered to the diver. It should be maintained until help 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. It is important to monitor the diver's condition and rule out neurological signs. 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. Decompression sickness can result from diving without the proper equipment. These are some common mistakes you should 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 were designed to permit direct ascent towards the surface. Regardless of the type of tank, decompression diving requires 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.
