1.3 ATA vs. 1.5 ATA Hyperbaric Chambers
Choosing between a 1.3 ATA and 1.5 ATA hyperbaric chamber starts with understanding what the pressure rating actually means, but pressure should not be the only factor in your decision. Chamber style, interior dimensions, access, oxygen equipment, manufacturer specifications, room requirements, and prescribed use all matter.
Bradshaw Oxygen carries both 1.3 ATA hyperbaric chambers and 1.5 ATA hyperbaric chambers, so you can compare multiple manufacturers and chamber styles instead of being limited to one product line.
What Does ATA Mean in a Hyperbaric Chamber?
ATA means atmospheres absolute, a measurement of total pressure. Normal atmospheric pressure at sea level is approximately 1.0 ATA. A chamber operating at 1.3 ATA increases the surrounding pressure above normal atmospheric pressure, while a chamber operating at 1.5 ATA reaches a higher total pressure.

Is 1.5 ATA Better Than 1.3 ATA?
A higher pressure number does not automatically make one chamber the better choice for every buyer. The appropriate chamber depends on the specific product, prescribed use, manufacturer instructions, chamber design, oxygen setup, accessibility requirements, available space, comfort, budget, and professional guidance.
For shopping purposes, it is often more useful to compare the complete system rather than choosing based on ATA alone.
What Else Should You Compare?
- Chamber position: Do you prefer to lie down, sit upright, recline, or walk into the chamber?
- Interior dimensions: Compare diameter, length, height, user size, and caregiver or accessibility needs.
- Entry design: Zipper placement, doorway size, vertical entry, and roll-in access can matter as much as pressure.
- Oxygen equipment: Determine what equipment is included and what compatible concentrator or oxygen delivery setup is required.
- Room requirements: Measure the intended space, doors, hallways, and clearance before ordering.
- Delivery and setup: Portable soft chambers and large hard-shell systems have very different freight and installation requirements.
- Support: Consider who will help with the chamber, oxygen equipment, replacement parts, troubleshooting, and setup after purchase.
