1.3 ATA vs. 1.5 ATA Hyperbaric Pressure
1.3 ATA and 1.5 ATA are chamber pressure settings, with 1.5 ATA representing a higher absolute pressure. This factual comparison explains pressure, approximate gauge pressure, and equalization considerations. OxyEdge products are wellness equipment and are not intended to diagnose, treat, cure, or prevent any disease.
1.3 ATA vs. 1.5 ATA
- Pressure above sea level: 1.3 ATA: 0.3 ATA above 1.0 — 1.5 ATA: 0.5 ATA above 1.0
- Approximate gauge pressure: 1.3 ATA: About 4.4 psi above ambient — 1.5 ATA: About 7.4 psi above ambient
- Category: 1.3 ATA: Mild hyperbaric range — 1.5 ATA: Mild hyperbaric range
- Relative pressure: 1.3 ATA: Lower of the two settings — 1.5 ATA: Higher of the two settings
- Equalization: 1.3 ATA: Required during pressure changes — 1.5 ATA: Required during pressure changes
- Setting selection: 1.3 ATA: Follow operating instructions — 1.5 ATA: Follow operating instructions
- OxyEdge availability: 1.3 ATA: Adjustable on OxyEdge chambers — 1.5 ATA: Adjustable on OxyEdge chambers
- Max pressure on OxyEdge chambers: 1.3 ATA: Up to 2.0 ATA — 1.5 ATA: Up to 2.0 ATA
Which is right for you?
- Home setting: Confirm the model's rated range, controls, room requirements, and operator instructions.
- Wellness center: Adjustable equipment can provide both listed settings when used according to its instructions.
- Spa: Compare room requirements, controls, training, and the model's rated pressure range.
- Athletic facility: Use documented operating procedures and select equipment based on specifications and facility needs.
What is the difference between 1.3 ATA and 1.5 ATA?
1.3 ATA is 0.3 atmospheres above sea-level pressure, while 1.5 ATA is 0.5 atmospheres above. Both fall within the mild hyperbaric range.
The higher setting represents greater total pressure. This comparison does not assign wellness outcomes to either setting.
How does pressure affect the session experience?
Occupants must equalize their ears as chamber pressure changes. The pressure change is greater at 1.5 ATA than at 1.3 ATA.
Pressurization should follow the equipment instructions and stop if an occupant cannot equalize comfortably.
Which pressure should you choose?
A trained operator should select settings within the equipment's rated range and follow the operating instructions. OxyEdge chambers allow the operator to set the target pressure.
Because OxyEdge hard-shell chambers reach up to 2.0 ATA, both 1.3 and 1.5 ATA are available on the same equipment.
Frequently Asked Questions
Is 1.5 ATA better than 1.3 ATA?
No setting is presented as better. They are different pressure levels, and operators should follow equipment instructions and applicable facility procedures.
Can one OxyEdge chamber do both pressures?
Yes. OxyEdge hard-shell chambers are adjustable and reach up to 2.0 ATA, so 1.3 and 1.5 ATA are both available on the same unit.
How should a setting be selected?
Use only settings within the model's rated range and follow the manufacturer instructions and applicable facility procedures.
