Decompression sickness, often call ed the bends, happens when a diver ascends too quickly and dissolved nitrogen forms bubbles in the blood and tissue. Interest in decompression sickness treatment tends to rise whenever a diving incident makes the news, though the condition itself is well documented and generally responds well to prompt care.
What Is Decompression Sickness?
The condition develops when gas bubbles expand faster than the body can safely release them, usually after a diver skips required stops during ascent. Symptoms range from mild joint discomfort to more serious neurological effects, depending on how much gas enters circulation.
What Are the Different Types of Decompression Sickness?
Decompression sickness is generally classified into two categories based on the parts of the body affected and the severity of symptoms. While both require prompt evaluation, Type II cases are typically considered more serious and may require more urgent medical intervention.
Type I Decompression Sickness
Type I decompression sickness primarily affects the joints, muscles, skin, and lymphatic system. Common symptoms include joint pain, fatigue, and skin changes such as mottling or itching. Although often considered the milder form, it should still be evaluated promptly to help prevent further complications.
Type II Decompression Sickness
Type II decompression sickness affects the nervous system, lungs, or cardiovascular system and is generally regarded as the more serious form of the condition. Symptoms may include weakness, numbness, difficulty breathing, dizziness, or neurological impairment, making immediate medical assessment and treatment essential.
What Is the First Treatment for Decompression Sickness?
Oxygen First Aid
Administering 100 percent oxygen as soon as symptoms appear is widely regarded as the first practical step, since it helps reduce bubble size and improves oxygen delivery to affected tissue while transport is arranged.
Recompression Therapy
Recompression therapy, delivered inside a hyperbaric chamber, is the primary medical treatment once a diver reaches a facility equipped to provide it. The process gradually reintroduces pressure to shrink nitrogen bubbles before slowly easing it back down under controlled conditions.
Hydration and Supportive Care
Dehydration is common after a dive and can worsen symptoms, so fluids are typically part of supportive care alongside oxygen. Monitoring vital signs during transport also helps medical teams track how a case is progressing.
How Long Does the Recovery Take?
Rest and Monitoring After Treatment
Recovery doesn’t always end once chamber treatment is complete, since some symptoms take days to fully resolve. Physicians typically recommend rest and a follow-up evaluation before a diver returns to the water.
How Can Divers Prevent It?
Proper dive training plays a major role in reducing the risk of decompression sickness, particularly by teaching safe ascent rates, safety stops, and dive planning techniques. Completing a dive course in Komodo Island, for example, gives new divers the opportunity to develop these essential skills under professional instruction before exploring more challenging dive sites.
Many programs offered through dive courses Komodo and local Komodo dive center operators emphasize safe diving practices, helping participants build the knowledge and confidence needed to minimize the risk of diving-related injuries.
When Should You Seek Emergency Care?
Any diver showing confusion, difficulty breathing, or weakness after a dive should be treated as an emergency, with oxygen and transport arranged immediately rather than waiting to see if symptoms pass on their own. Once recovered and medically cleared to dive again, reviewing dive planning, ascent techniques, and safety procedures with reputable professionals such as those at a Komodo dive center in Indonesia, can help reinforce good diving practices and reduce the likelihood of similar incidents in the future.
Wrapping Up
Decompression sickness is manageable when caught early and treated through oxygen, recompression therapy, and proper monitoring. Understanding the condition beforehand, and knowing where the nearest chamber is located, remains one of the more practical steps a diver can take before heading out.
