1.5 ATA vs. 2.0 ATA Hyperbaric Pressure
1.5 ATA is a mild hyperbaric pressure, while 2.0 ATA is the higher end of the range offered by OxyEdge hard-shell chambers. The higher pressure increases how much oxygen dissolves into the body's fluids per session. This comparison outlines the practical differences and helps you decide which setting fits your goals.
1.5 ATA vs. 2.0 ATA
- Pressure above sea level: 1.5 ATA: 0.5 ATA above 1.0 — 2.0 ATA: 1.0 ATA above 1.0
- Approximate gauge pressure: 1.5 ATA: About 7.4 psi above ambient — 2.0 ATA: About 14.7 psi above ambient
- Dissolved oxygen effect: 1.5 ATA: Moderate within mild range — 2.0 ATA: Highest on OxyEdge chambers
- Equalization demand: 1.5 ATA: Modest, comfortable for most — 2.0 ATA: Greater, gradual ascent helps
- Chamber requirement: 1.5 ATA: Achievable on OxyEdge hard-shell — 2.0 ATA: Requires rigid hard-shell construction
- Session pacing: 1.5 ATA: Shorter pressurization time — 2.0 ATA: Longer pressurization and descent
- OxyEdge availability: 1.5 ATA: Adjustable on OxyEdge chambers — 2.0 ATA: Maximum on OxyEdge chambers
- Typical user: 1.5 ATA: General wellness users — 2.0 ATA: Users seeking the higher mild range
Which is right for you?
- Home user: Home users comfortable with pressure may choose 2.0 ATA, while others prefer 1.5 ATA for a gentler session.
- Wellness center: A wellness center benefits from chambers that offer the full 1.5 to 2.0 ATA range for varied client needs.
- Medical spa: A medical spa can offer 1.5 ATA as a standard experience and 2.0 ATA for clients wanting the higher setting.
- Athletic facility: Athletic facilities often value the 2.0 ATA capability for a higher dissolved-oxygen environment.
What is the difference between 1.5 ATA and 2.0 ATA?
1.5 ATA is 0.5 atmospheres above sea level, while 2.0 ATA is a full atmosphere above sea level, doubling the ambient pressure.
At 2.0 ATA more oxygen dissolves into the body's plasma than at 1.5 ATA, which is why higher-pressure sessions require rigid hard-shell chambers.
Why does 2.0 ATA require a hard-shell chamber?
Reaching 2.0 ATA requires a rigid pressure vessel engineered to contain the higher pressure safely. OxyEdge hard-shell chambers are built for this range.
Soft-shell chambers generally cannot reach 2.0 ATA, which is one reason OxyEdge manufactures only hard-shell chambers.
How do pressurization and comfort compare?
A 2.0 ATA session involves a longer, more gradual pressurization and depressurization than 1.5 ATA, giving occupants time to equalize comfortably.
OxyEdge chambers manage the ascent and descent through monitored systems so both pressures remain comfortable for most users.
Frequently Asked Questions
Is 2.0 ATA safe for wellness use?
2.0 ATA is the maximum operating pressure on OxyEdge hard-shell chambers and is used with gradual pressurization and monitored safety systems. Users choose the setting that fits their comfort.
Can I switch between 1.5 and 2.0 ATA?
Yes. OxyEdge chambers are adjustable, so operators can set sessions anywhere up to 2.0 ATA on the same unit.
Do I need a special chamber for 2.0 ATA?
Yes. Reaching 2.0 ATA requires a rigid hard-shell chamber engineered for that pressure, which is what OxyEdge manufactures.
