How does the decompression sickness bend work

Information on Skin Bends for Divers - 2021

Decompression sickness can come in many forms. An often overlooked form of decompression sickness is cutaneous decompression sickness, also known as Skin bends. Some forms of skin flexion may require recompression treatment in a hyperbaric chamber, while others may go away on their own. Regardless of the type, all skin flexions should be checked out by a hyperbaric doctor, here is some basic information about skin curves, including the different shapes. how to recognize a skin curvature; and other problems this type of bend can indicate.

decompression sickness

The term decompression sickness describes a variety of ailments caused by absorbed nitrogen leaking from solution in a person's body. In diving, this happens because a high level of nitrogen is absorbed when a person is exposed to increased pressure underwater. If this excess nitrogen is not naturally metabolized during a diver's ascent, bubbles form and can build up in various parts of the diver's body, such as the joints or skin capillaries. Remember, decompression sickness is rare and unlikely if you use proper diving techniques.

Decutation disorder of the skin

Most diving doctors agree that decompression sickness of the skin is caused by nitrogen bubbles in the capillaries of the skin. Alternatively, skin flexions can also be caused by the body's defense reaction against these tiny nitrogen bubbles, releasing histamines and other chemicals that mimic an allergic reaction. Whatever the cause, skin bends usually appear within a few minutes to a few hours after surfacing.

Types of Skins Bends:

There are different forms of skin curvature. Some are heavier than others:

  • The itchy rash: The mildest form of skin decompression sickness is a rash, most often on the upper body, chest, back, or shoulders. The rash is similar to sunburn and is usually itchy. Divers have described the itchy sensation as the feeling of tiny insects crawling on the skin. While this form of decompression sickness is mild and may not require decompression sickness in a hyperbaric chamber, any mysterious rashes that occur after diving should be checked out by a diving doctor. Recreational divers often overlook a decompression stop rash caused by other factors or believe that it is not severe. However, as noted on the London Diving Chamber's website, "Having one curve means that one day the decompression was inadequate. Many curves, even if only skin flexions indicate potentially dangerous, identifiable risk factors." In other words, just because a bend might not require recompression doesn't mean it isn't a problem.
  • Marbling or cutis marmorata:Cutis marmorata describes a more pronounced form of skin flexion. The characteristic "marbling" of the skin in this type of decompression sickness is difficult to understand. Photos of Cutis marmorata show light red, purple, or even bluish skin with an irregular, marble-like pattern. As with rash, decompression sickness is most common on the chest, torso, back, and shoulders. It has also been reported to be extremely itchy. The coloration may appear in spots or, in severe cases, start on the chest and spread downwards. Unlike the rash form, cutis marmorata is considered severe. In most cases, recompression is required. Cutis marmorata has been found to be associated with other, more serious forms of decompression sickness, such as neurological decompression sickness.
  • Lymphatic decompression sickness: Divers can identify decompression sickness by a swollen area (or areas) that hold in a depression for a few moments when they are depressed. Lymphatic decompression sickness is also characterized by the peculiar formation of the skin over the swelling, similar to the pitted skin of an orange. Lymphatic decompression sickness has been reported to go away on its own. However, it goes away faster with treatment. As with other forms of curvature of the skin, decompression sickness can occur with or before other more serious forms of decompression sickness. Any suspicious swelling after a dive should be examined by a diving doctor.

The importance of recognizing skin bends

Divers should be able to identify decompression sickness of the skin so that they can take necessary precautions, such as: B. Immediately inhaling oxygen, seeking medical examination, or recompression. As with any other type of decompression sickness, if a skin flexion is detected, a diver should refrain from further diving until he has consulted a diving doctor.

Skin bends can precede more serious problems

Symptoms of decompression sickness are known to appear before or along with symptoms of more severe types of decompression sickness, such as: B. neurological decompression sickness occur. A diver who notices a skin flexion and immediately goes to a diving doctor will have a head start in treating any other symptoms that may arise. When treating decompression sickness, time is of the essence. The earlier a diver is in the recompression chamber, the higher his chances of full recovery. Detecting a skin flexion can be the first step towards timely and effective treatment.

Skin bends can indicate a PFO

A patented foramen ovale (or PFO) is a heart condition that is believed to cause a higher risk of decompression sickness. Diving physicians have begun to see a possible correlation between cases of skin flexions from dives within the recreational tables and the presence of a PFO. Divers who have had skin wrinkles in the past should test a PFO.

Preparation is nine tenths of the battle

Decompression sickness is rare. Most divers will never experience decompression sickness. However, divers should familiarize themselves with the various types and symptoms of decompression sickness so that they can respond properly and efficiently in the unlikely event that decompression sickness does occur. Skin flexions can be one of the most common manifestations of decompression sickness, but it is often misidentified as sunburn or other non-diving discomfort and is not reported. Skin flexions can indicate improper diving practices or a medical predisposition to decompression sickness such as PFO. Although it can only be a skin depth, decompression sickness of the skin must be taken seriously.
