Can hyperbaric oxygen therapy cause oxygen toxicity?
Oxygen toxicity is a real but uncommon risk of HBOT, and clinical protocols are designed specifically to prevent it — using controlled pressures, limited session times and periodic “air breaks”. At certified centres, serious oxygen toxicity is rare.
The fuller answer
Breathing high-concentration oxygen under pressure for long enough can, in principle, irritate the lungs or — rarely — affect the nervous system (a brief seizure being the most talked-about example). This is why HBOT is delivered within careful limits rather than open-endedly.
Standard protocols keep pressure and session length within well-established safe ranges, and many include scheduled “air breaks” — short periods breathing normal air — precisely to reduce oxygen-toxicity risk. Staff also screen for factors, such as certain medications or fever, that can raise susceptibility.
The practical takeaway: at a PVHO-certified centre following proper protocols, serious oxygen toxicity is rare, and any mild symptoms are managed immediately. This is another reason to choose a genuine medical-grade service — read our is HBOT safe guide.

How is oxygen toxicity prevented in HBOT?
Through controlled pressure and time limits, scheduled air breaks, and screening for risk factors before treatment.
