Causes & Risk Factors
Several factors can contribute to Scuba Diving Injuries.
The primary cause of most scuba diving injuries relates to pressure changes that occur underwater.
The primary cause of most scuba diving injuries relates to pressure changes that occur underwater. As divers descend, water pressure increases dramatically - doubling every 33 feet of depth. This increased pressure compresses air spaces in the body, and if pressure isn't equalized properly, it can damage tissues in the ears, sinuses, lungs, or other gas-filled areas. Barotrauma occurs when these pressure differences cause tissue damage, most commonly affecting the middle ear, sinuses, or lungs.
Decompression sickness, often called 'the bends,' happens when divers ascend too quickly from depth.
Decompression sickness, often called 'the bends,' happens when divers ascend too quickly from depth. During the dive, compressed air dissolves extra nitrogen into the bloodstream and tissues. If ascent is too rapid, this dissolved nitrogen forms bubbles in the blood and tissues, similar to opening a shaken soda bottle. These bubbles can block blood flow or directly damage tissues, causing symptoms ranging from joint pain to life-threatening complications.
Other diving injuries can result from equipment malfunctions, marine life encounters, underwater currents, or simple accidents like cuts from coral or rocks.
Other diving injuries can result from equipment malfunctions, marine life encounters, underwater currents, or simple accidents like cuts from coral or rocks. Poor visibility, cold water, and inexperience can increase the risk of these secondary injuries. Panic underwater can lead to rapid ascent or breath-holding, both dangerous behaviors that significantly increase injury risk.
Risk Factors
- Rapid ascent from depth
- Skipping safety stops during ascent
- Diving with a cold or sinus congestion
- Poor equalization techniques
- Diving beyond training level or experience
- Multiple deep dives in one day
- Flying within 18-24 hours after diving
- Dehydration before or during diving
- Obesity or poor physical fitness
- Previous history of decompression sickness
- Heart conditions or lung disease
- Age over 50 years
Diagnosis
How healthcare professionals diagnose Scuba Diving Injuries:
- 1
Diagnosing diving injuries requires a detailed history of the dive profile, including maximum depth, bottom time, ascent rate, and when symptoms began.
Diagnosing diving injuries requires a detailed history of the dive profile, including maximum depth, bottom time, ascent rate, and when symptoms began. Emergency physicians and diving medicine specialists look for specific patterns that suggest pressure-related injuries versus other causes. They'll ask about equalization difficulties, rapid ascent, safety stop adherence, and any equipment problems during the dive.

Physical examination focuses on the ears, lungs, nervous system, and skin.
Physical examination focuses on the ears, lungs, nervous system, and skin. Doctors use otoscopes to check for eardrum damage, listen to lung sounds for signs of air embolism, and test reflexes and sensation to detect neurological symptoms. For suspected decompression sickness, they look for skin changes, joint swelling, and perform detailed neurological testing to identify any subtle deficits.

Imaging studies may include chest X-rays to check for lung overexpansion injuries, CT scans for suspected air embolism, or MRI for spinal cord decompression sickness.
Imaging studies may include chest X-rays to check for lung overexpansion injuries, CT scans for suspected air embolism, or MRI for spinal cord decompression sickness. However, treatment often begins based on clinical suspicion rather than waiting for test results, especially in serious cases. Blood tests can help rule out other conditions but aren't specific for diving injuries. The key is recognizing that any symptoms developing during or shortly after diving should be considered diving-related until proven otherwise.
Complications
- Serious diving injuries can lead to permanent disabilities if not treated promptly and appropriately.
- Decompression sickness affecting the spinal cord may cause lasting paralysis or weakness, while brain involvement can result in cognitive impairment, speech problems, or personality changes.
- These neurological complications are more likely with delayed treatment or severe cases, emphasizing the importance of immediate medical attention for any post-dive symptoms.
- Lung overexpansion injuries can cause pneumothorax (collapsed lung), mediastinal emphysema, or arterial gas embolism.
- Air embolism to the brain represents a diving emergency that can cause stroke-like symptoms, seizures, or cardiac arrest.
- Even with successful treatment, some patients may experience residual effects.
- Ear barotrauma can lead to permanent hearing loss, chronic dizziness, or recurrent infections if the eardrum is severely damaged.
- Most complications are preventable through proper diving practices and immediate treatment when injuries occur.
Prevention
- Proper training through certified diving organizations provides the foundation for injury prevention.
- Divers should never exceed their training level or comfort zone, and regular skills refresher courses help maintain safe practices.
- Learning correct equalization techniques and practicing them regularly prevents most ear and sinus injuries.
- The key is equalizing early and often during descent, never forcing equalization if it doesn't work easily.
- Following established diving protocols dramatically reduces injury risk.
- This includes making slow, controlled ascents with safety stops, staying well within no-decompression limits, and surface intervals between dives.
- Conservative dive planning with safety margins accounts for variations in individual physiology and environmental conditions.
- Using dive computers helps monitor depth and time limits, but understanding the underlying principles remains essential.
- Physical fitness and health management play crucial roles in diving safety.
- Divers should avoid diving with colds or sinus congestion, stay well-hydrated, and maintain good cardiovascular fitness.
- Regular medical check-ups can identify conditions that might increase diving risks.
- Equipment maintenance and pre-dive safety checks prevent mechanical failures that could lead to emergency ascents or other dangerous situations.
Immediate treatment for serious diving injuries focuses on high-flow oxygen therapy and rapid transport to appropriate medical facilities.
Immediate treatment for serious diving injuries focuses on high-flow oxygen therapy and rapid transport to appropriate medical facilities. Pure oxygen helps eliminate nitrogen bubbles in decompression sickness and treats air embolism by reducing bubble size. Emergency responders trained in diving medicine can start this treatment in the field, often providing significant symptom relief.
Hyperbaric oxygen therapy represents the definitive treatment for decompression sickness and air embolism.
Hyperbaric oxygen therapy represents the definitive treatment for decompression sickness and air embolism. Patients enter a pressurized chamber where they breathe pure oxygen under increased pressure, which compresses bubbles and enhances nitrogen elimination. Treatment typically lasts several hours and may require multiple sessions. The sooner treatment begins, the better the outcomes, which is why diving emergency hotlines operate 24/7 to coordinate rapid chamber access.
Barotrauma injuries often heal with conservative management.
Barotrauma injuries often heal with conservative management. Ear barotrauma may require decongestants, pain relief, and sometimes antibiotics if infection develops. Lung overexpansion injuries need careful monitoring, oxygen therapy, and sometimes chest tube placement if pneumothorax occurs. Sinus squeeze usually resolves with decongestants and avoiding further diving until healing is complete.
Pain management, anti-inflammatory medications, and supportive care help manage symptoms during recovery.
Pain management, anti-inflammatory medications, and supportive care help manage symptoms during recovery. Some diving injuries may require specialist follow-up with ENT doctors for ear problems, pulmonologists for lung issues, or neurologists for persistent neurological symptoms. Return to diving requires medical clearance and often additional training to prevent recurrence. Recent advances in hyperbaric medicine and better understanding of decompression physiology have significantly improved outcomes for serious diving injuries.
Living With Scuba Diving Injuries
Recovery from diving injuries varies significantly depending on the type and severity of the condition. Many divers with mild barotrauma can return to normal activities within days to weeks, while those with decompression sickness may need months of rehabilitation. Following medical advice about rest, gradual return to physical activity, and avoiding further diving until cleared is essential for optimal recovery.
