Causes & Risk Factors
Several factors can contribute to Barotrauma (Pressure Injuries).
Barotrauma happens when pressure outside your body changes faster than the air pressure inside your body's cavities can equalize.
Barotrauma happens when pressure outside your body changes faster than the air pressure inside your body's cavities can equalize. Your middle ear, sinuses, lungs, and other air-filled spaces normally maintain the same pressure as your surroundings through small tubes and passages. When external pressure changes rapidly, these natural pathways can't keep up, creating a pressure difference that stretches or compresses tissues.
The most common trigger is rapid altitude changes during air travel, where cabin pressure shifts can affect your ears and sinuses.
The most common trigger is rapid altitude changes during air travel, where cabin pressure shifts can affect your ears and sinuses. Scuba diving presents even greater challenges, as water pressure increases dramatically with depth. Every 33 feet underwater roughly doubles the pressure on your body. Other causes include hyperbaric oxygen therapy, mountain climbing, and certain medical procedures that involve pressure chambers.
Blockages in your body's pressure-equalizing systems make barotrauma more likely.
Blockages in your body's pressure-equalizing systems make barotrauma more likely. Congestion from colds, allergies, or sinus infections can prevent proper pressure equalization. Some people have naturally narrow or curved eustachian tubes that don't function as efficiently. Rapid decompression, such as in aircraft emergencies or diving accidents, can cause severe barotrauma because there's no time for gradual pressure adjustment.
Risk Factors
- Flying or diving with cold or sinus congestion
- Frequent air travel or diving activities
- Narrow or blocked eustachian tubes
- Recent upper respiratory infections
- Chronic allergies or sinusitis
- Smoking or exposure to secondhand smoke
- Previous ear surgery or injury
- Rapid altitude changes in sports or work
- Using certain medications that affect nasal passages
- Sleeping during airplane descent
Diagnosis
How healthcare professionals diagnose Barotrauma (Pressure Injuries):
- 1
Doctors typically diagnose barotrauma based on your symptoms and recent exposure to pressure changes.
Doctors typically diagnose barotrauma based on your symptoms and recent exposure to pressure changes. Your physician will ask detailed questions about when symptoms started, what activities you were doing, and how severe your discomfort is. A physical examination focuses on your ears, nose, throat, and sometimes your chest, looking for signs of pressure-related damage.

The most common diagnostic tool is otoscopy, where doctors use a lighted instrument to examine your eardrums.
The most common diagnostic tool is otoscopy, where doctors use a lighted instrument to examine your eardrums. They're looking for redness, bulging, retraction, or fluid behind the eardrum. For sinus barotrauma, doctors may check for tenderness around your forehead, cheeks, and nose. Hearing tests might be performed if you're experiencing significant hearing loss or if symptoms persist.

In severe cases or when complications are suspected, additional tests may be necessary.
In severe cases or when complications are suspected, additional tests may be necessary. CT scans can reveal sinus damage or fluid accumulation. Chest X-rays help identify lung barotrauma in divers or people exposed to rapid decompression. Tympanometry measures how well your eardrum moves, indicating whether your middle ear is functioning normally. Blood tests are rarely needed unless doctors suspect infection as a complicating factor.
Complications
- Most barotrauma complications involve the ears and can range from temporary discomfort to permanent damage.
- Ruptured eardrums are the most common serious complication, usually healing within weeks but sometimes requiring surgical repair.
- Persistent hearing loss can occur if the delicate bones of the middle ear are damaged or if scar tissue forms.
- Some people develop chronic ear infections following barotrauma, especially if bacteria enter through damaged tissues.
- Severe complications are more likely with lung barotrauma, particularly in diving accidents.
- Pneumothorax, where air escapes into the chest cavity, can be life-threatening and requires emergency treatment.
- Air embolism occurs when air bubbles enter the bloodstream and can cause stroke-like symptoms or heart problems.
- These complications require immediate hyperbaric treatment and intensive medical care.
- While rare, they underscore the importance of proper diving training and safety protocols.
Prevention
- The best prevention strategy is avoiding pressure exposure when you have conditions that block your natural pressure-equalizing mechanisms.
- Don't fly or dive when you have a cold, sinus infection, or severe allergies.
- If you must travel, use decongestants before and during your trip, but follow package directions carefully.
- Staying hydrated helps keep mucous membranes functioning properly.
- For air travelers, simple techniques can prevent ear barotrauma.
- Stay awake during takeoff and landing so you can actively swallow and yawn.
- Chew gum or suck on candy to promote swallowing.
- The Valsalva maneuver can help, but do it gently and frequently rather than forcefully.
- Consider using filtered earplugs designed for flying, which slow pressure changes to give your ears more time to adjust.
- Divers need more sophisticated prevention strategies.
- Learn proper equalization techniques before diving and practice them regularly.
- Descend slowly and equalize pressure frequently, not just when you feel discomfort.
- Never dive with congestion, and consider postponing trips if you've been sick recently.
- Take diving courses from certified instructors who can teach you safe practices and emergency procedures.
- Regular equipment maintenance ensures your gear won't contribute to pressure-related problems.
Most mild barotrauma resolves on its own within hours to days as your body naturally equalizes pressure and heals minor tissue damage.
Most mild barotrauma resolves on its own within hours to days as your body naturally equalizes pressure and heals minor tissue damage. Pain relief starts with over-the-counter medications like ibuprofen or acetaminophen, which also help reduce inflammation. Decongestants, either oral or nasal sprays, can help open blocked passages, though nasal sprays should only be used for a few days to avoid rebound congestion.
For ear barotrauma, gentle techniques can help restore normal pressure.
For ear barotrauma, gentle techniques can help restore normal pressure. The Valsalva maneuver involves gently blowing while pinching your nose and closing your mouth, but this should be done carefully to avoid further damage. Yawning, swallowing, or chewing gum can also help. Warm compresses applied to affected ears may provide comfort and promote healing.
Severe cases require more aggressive treatment.
Severe cases require more aggressive treatment. Prescription nasal steroids can reduce inflammation in blocked passages. If your eardrum has ruptured, doctors will monitor healing and prescribe antibiotics to prevent infection. You'll need to keep your ear dry and avoid further pressure exposure. In rare cases, surgical procedures like myringotomy (making a small hole in the eardrum) or tympanostomy tube placement may be necessary to equalize pressure.
Lung barotrauma from diving accidents represents a medical emergency requiring immediate treatment.
Lung barotrauma from diving accidents represents a medical emergency requiring immediate treatment. This may involve oxygen therapy, chest tube insertion to remove trapped air, or hyperbaric chamber treatment. Recovery from serious barotrauma can take weeks to months, and some people may need to avoid activities involving pressure changes permanently.
Living With Barotrauma (Pressure Injuries)
People who've experienced barotrauma often worry about future episodes, but most can return to normal activities with proper precautions. If you're a frequent flyer, invest in quality earplugs designed for air travel and learn reliable equalization techniques. Keep decongestants handy when traveling, and don't hesitate to delay trips if you're congested. Consider upgrading to business class occasionally, as larger aircraft used on longer routes typically have better cabin pressure systems.
