HBOT Protocol Basics — Why Specs Matter
Published: December 2025
When comparing chambers, “protocol” is where marketing meets physics: pressure, oxygen dose, and time. Two chambers marketed as “HBOT” can deliver very different exposures depending on ATA, oxygen delivery, and ventilation.
FAQ (quick)
What does ATA actually change?
ATA changes oxygen partial pressures substantially, which is why pressure stability and accurate specs matter in comparisons.
Why does oxygen delivery method matter?
Mask/BIBS vs ambient oxygen affects dose and requirements (oxygen source, flow rates, ventilation) and should be documented.
How do I compare session comfort fairly?
Compare compression/decompression ramp control, ventilation, noise, and service support for your region.
Key terms
- ATA: absolute pressure. Higher ATA changes oxygen partial pressures substantially.
- Oxygen delivery: mask/BIBS vs ambient oxygen; flow rates and source capacity matter.
- Session profile: compression/decompression ramps influence comfort and safety.
Why this changes buying decisions
A buyer focused on clinic throughput will prioritize reliability, service, and safety systems. A buyer focused on home wellness may prioritize comfort, operating costs, and support — but should still demand clear documentation.
