Common Patient-Related Issues During Treatment
Hyperbaric oxygen therapy can cause several patient-related challenges during sessions. Understanding these issues helps operators prevent problems and respond appropriately when they occur.
Barotrauma and Ear Pressure Issues
Barotrauma is the most common patient issue with hyperbaric oxygen therapy. This happens when pressure changes affect body parts that contain air, particularly the ears and sinuses.
The ears experience problems most often during chamber sessions. Patients may feel discomfort when the chamber pressure increases or decreases. Some people cannot equalize the pressure in their ears properly, leading to middle ear barotrauma.
Ear Barotrauma Symptoms
- Ear pain during pressurization
- Temporary hearing changes
- Fullness or pressure sensation
- Fluid accumulation in severe cases
Prevention Methods
- Teaching proper ear equalization techniques
- Using decongestants when appropriate
- Slower pressurization rates
- Stopping if significant pain occurs
The sinuses can also experience discomfort from pressure changes. Patients may feel pain in their face, forehead, or around their eyes. People with sinus infections or congestion should delay treatment until these conditions clear.
Oxygen Exposure Considerations
Oxygen toxicity happens when patients breathe concentrated oxygen for extended periods at higher pressures. This is a consideration during hyperbaric oxygen therapy that requires proper session management. The brain is most sensitive to high oxygen levels, which can affect cellular function.
Seizures represent the most serious result of oxygen toxicity. Warning signs before seizures may include nausea, dizziness or confusion, muscle twitching, and vision problems. Understanding session length limits helps prevent these issues—see How Long Should You Stay in a Hyperbaric Chamber .
Risk Factors for Oxygen Toxicity
- Extended therapy sessions beyond recommended times
- Very high chamber pressures
- Fever or concurrent illness
- Certain medications that increase sensitivity
- Low blood sugar levels
Treatment facilities prevent oxygen toxicity by limiting session time and providing air breaks during treatment. Following established protocols for pressure levels and duration minimizes these risks significantly.
Vision and Sinus Changes
Vision changes happen to some patients during hyperbaric oxygen therapy. The oxygen-rich environment can temporarily affect the lens in the eye. Most patients develop temporary nearsightedness, meaning they cannot see far away objects as clearly.
This effect usually resolves weeks or months after treatment ends. Some patients need temporary vision correction during treatment sessions. Sinus problems also occur from pressure changes, including sinus pressure and discomfort, congestion, occasional sinus infections, and rarely, nosebleeds.
Issue | Duration | Management |
---|---|---|
Temporary Nearsightedness | Weeks to months post-treatment | Temporary vision correction if needed |
Sinus Pressure | During sessions | Decongestants, slower pressurization |
Ear Fullness | During and shortly after | Equalization techniques |
Patients with active sinus infections or severe colds should postpone chamber use. Blocked sinuses cannot handle pressure changes safely. Eye exams before starting treatment and sinus medication when appropriate help manage these issues.
Claustrophobia and Psychological Responses
Claustrophobia affects some patients in hyperbaric chambers. The enclosed space triggers anxiety or discomfort in certain individuals. Symptoms during sessions may include increased heart rate, nervousness, breathing difficulty sensations, feeling confined, and desire to exit early.
Anxiety responses can range from mild to severe. Some patients feel nervous but can complete treatment with support. Others experience significant distress that makes therapy challenging. Clear hyperbaric chambers help some patients feel less enclosed. Entertainment options like music or videos can provide helpful distraction.
Managing Claustrophobia
- Choosing larger chamber models when possible
- Clear viewing windows to reduce enclosed feeling
- Practice sessions to build comfort gradually
- Relaxation techniques and breathing exercises
- Support person nearby during initial sessions
- Anti-anxiety approaches when recommended by healthcare provider
Some patients cannot complete hyperbaric oxygen therapy due to severe claustrophobia. Healthcare providers must consider alternative treatment options for these individuals or work gradually to build tolerance.
Equipment Malfunctions and Technical Issues
Beyond patient-related concerns, hyperbaric chambers can experience equipment problems that affect operation. Understanding common technical issues helps operators troubleshoot effectively.
Typical Chamber Malfunctions
Pressure system failures rank among the most common hyperbaric chamber equipment problems. These include pressure sensors giving incorrect readings, compressors failing to reach target pressures, and automatic pressure controls malfunctioning. Regular calibration prevents many sensor issues.
Oxygen delivery system issues frequently occur in chambers. Problems include oxygen concentrators producing inadequate purity levels, flow meters providing inaccurate measurements, and oxygen supply lines developing leaks. Regular testing of oxygen purity ensures therapeutic effectiveness.
Pressure System Problems
- Sensor calibration drift
- Compressor performance issues
- Control system malfunctions
- Pressure gauge inaccuracies
Oxygen Delivery Issues
- Concentrator purity problems
- Flow meter inaccuracies
- Supply line leaks
- Tank supply depletion
Door seal failures create significant operational problems. Worn rubber seals allow pressure loss during treatments. Damaged locking mechanisms prevent proper chamber closure. Regular seal inspection and timely replacement prevent these issues.
Electrical system malfunctions affect chamber operations regularly. Circuit breakers may trip unexpectedly, control panel displays show error codes, and communication systems between chambers and operators can fail. Maintaining electrical components according to manufacturer schedules reduces these problems.

Prevention Through Proper Operation
Most hyperbaric chamber problems can be prevented through proper operation techniques and regular maintenance schedules. Operators must focus on correct pressure control, patient screening, and equipment care to ensure safe treatment delivery.
Proper Chamber Operation and Pressure Regulation
Pressure control systems require daily calibration checks before therapy sessions. Operators should verify that gauges read zero at atmospheric pressure. Any deviation needs immediate attention. Gradual pressurization prevents ear injuries and equipment stress.
The chamber should pressurize slowly according to manufacturer specifications, typically 2 psi per minute or slower. Patients with recent ear procedures or congestion need even slower rates. Emergency protocols must be practiced regularly. All operators should know how to safely decompress the chamber if needed.
Daily Operation Checklist
- Verify pressure gauge calibration (should read zero)
- Test emergency decompression systems
- Check oxygen purity levels (should be 95%+ for concentrators)
- Inspect door seals for damage
- Test communication systems
- Verify temperature monitoring function
Temperature monitoring prevents overheating during oxygen treatment. Chamber temperatures above recommended levels increase discomfort and safety concerns. Cooling systems need regular filter changes to maintain proper function. Oxygen purity testing ensures therapeutic effectiveness.
Patient Screening and Session Adaptation
Patients with certain conditions need special attention during treatment. Those with diabetes should monitor blood sugar before and after sessions, as hyperbaric oxygen can affect glucose levels. Lung conditions require special evaluation before treatment begins.
Ear problems need assessment before treatment. Patients who cannot clear their ears risk barotrauma. Those with recent ear procedures may need delayed treatment until healing completes. Cold and flu symptoms prevent safe pressurization—congested patients cannot equalize ear pressure properly. Treatment should wait until symptoms clear completely.

Equipment Maintenance and Troubleshooting
Regular maintenance prevents most equipment problems and extends chamber lifespan. Establishing consistent maintenance routines ensures reliable operation.
Routine Maintenance Procedures
Daily cleaning after each use prevents contamination and equipment damage. Remove all personal items and wipe down surfaces with approved cleaning solutions only. Air quality monitoring detects problems before they become serious issues.
Maintenance Task | Frequency | Purpose |
---|---|---|
Surface Cleaning | After each use | Prevent contamination |
Seal Inspection | Weekly | Detect wear early |
Sensor Calibration | Monthly | Ensure accuracy |
Professional Service | Every 6 months | Comprehensive inspection |
Professional servicing should happen every six months minimum. Certified technicians must inspect pressure vessels, valves, and safety systems. Only trained professionals should perform major repairs. Door seals need regular inspection for cracks or wear. Damaged seals cause pressure loss during therapy sessions. Replace seals immediately when damage appears.
Troubleshooting Common Issues
When oxygen levels appear incorrect, check oxygen analyzers first. Calibrate the sensors using certified calibration gas mixtures. Inspect oxygen supply connections for loose fittings or damaged tubing. Tighten connections and replace cracked sections.
For pressure regulation problems, verify that compressors reach target pressures. Check for air leaks in the system by applying soap solutions to connections during pressurization. Look for bubble formation indicating leak locations. Monitor pressure decay rates during sessions—excessive loss indicates seal degradation.
