Diving in the Maldives is a dream for many, but understanding the risks associated with deep-sea diving, such as bends, is essential to ensure a safe and enjoyable experience. Also known as decompression sickness (DCS), bends occur when nitrogen bubbles form in the bloodstream due to rapid ascent after a deep dive. Given the Maldives’ reputation as a world-class diving destination, every diver must be aware of this condition to maximize safety and enjoyment underwater.
What Are Bends?
Bends, or decompression sickness, is a condition caused by rapid pressure changes during ascent after deep diving. When a diver spends time underwater at significant depths, nitrogen dissolves into the bloodstream due to increased pressure. If the ascent is too fast, the nitrogen does not have enough time to escape gradually, leading to the formation of nitrogen bubbles in the body. These bubbles can cause various symptoms, ranging from mild discomfort to life-threatening complications.
Symptoms of Bends
The symptoms of bends can vary depending on the severity of the condition and how quickly nitrogen bubbles form in the bloodstream. Some common symptoms include:
- Joint and muscle pain (often referred to as “the bends”)
- Fatigue and dizziness
- Nausea and vomiting
- Skin rash and itching
- Numbness or tingling sensations
- Difficulty breathing
- Confusion or cognitive impairment
Severe cases can lead to paralysis, unconsciousness, and even death if not treated promptly.
Causes and Risk Factors
Bends primarily occur when a diver ascends too quickly without allowing the body to eliminate excess nitrogen through controlled decompression. Several factors can increase the risk of decompression sickness, including:
- Multiple Dives: Repetitive diving within a short period increases nitrogen saturation in the body.
- Deep Dives: The deeper a diver goes, the more nitrogen is absorbed, raising the risk of bends.
- Fast Ascent: Rising to the surface too quickly does not allow nitrogen to exit the bloodstream gradually.
- Skipping Safety Stops: Safety stops help regulate nitrogen release and reduce the risk of DCS.
- Dehydration: Insufficient water intake can thicken the blood, making it harder for nitrogen to escape.
- Obesity and Poor Physical Health: Higher fat content can retain nitrogen longer, increasing the likelihood of bends.
Preventing Bends While Diving in the Maldives
The Maldives offers some of the world’s most stunning dive sites, including vibrant coral reefs and encounters with manta rays, whale sharks, and other marine life. To fully enjoy these underwater wonders while avoiding decompression sickness, divers must follow proper safety measures:
1. Follow a Slow and Controlled Ascent
Ascending too fast is the primary cause of bends. Divers should follow the standard rule of not exceeding a rise rate of 9–10 meters per minute.
2. Use a Dive Computer
A dive computer helps monitor depth, ascent rate, and decompression stops, ensuring divers follow a safe ascent plan.
3. Perform Safety Stops
Making safety stops at 3 to 5 meters for at least three minutes before surfacing allows nitrogen to escape slowly and reduces the risk of DCS.
4. Stay Hydrated
Drinking plenty of water before and after diving helps maintain proper blood circulation, assisting nitrogen elimination.
5. Plan Dives with Proper Surface Intervals
Allowing sufficient time between multiple dives gives the body time to expel nitrogen, reducing the likelihood of bends.
6. Avoid Alcohol Before and After Diving
Alcohol can dehydrate the body and impair judgment, increasing the risk of decompression sickness.
7. Maintain Good Physical Health
Regular exercise, maintaining a healthy weight, and avoiding smoking can enhance a driver’s ability to manage nitrogen levels effectively.
Treatment for Bends
If a diver shows signs of decompression sickness, immediate medical attention is required. The Maldives is home to several medical facilities equipped to handle diving-related emergencies.
Steps to Take in Case of Bends:
- Administer Oxygen: Providing 100% oxygen helps reduce nitrogen levels in the bloodstream.
- Lie the Diver Flat: Keeping the diver in a horizontal position prevents nitrogen bubbles from traveling to critical areas.
- Hydrate and Keep Calm: Drinking fluids and staying relaxed can aid in recovery.
- Seek Hyperbaric Chamber Treatment: A hyperbaric oxygen therapy chamber is the most effective treatment for bends. The Maldives has several hyperbaric chambers available for divers in need of emergency care.
