Flexible chamber
Five one-person formats built around upright, reclined, lie-down or wheelchair-accessible positioning.
Pressure matters, but chamber structure, oxygen delivery, room planning and support matter too.
ATA means atmospheres absolute: the total pressure inside the chamber relative to a vacuum. Normal sea-level pressure is approximately 1.0 ATA. A product’s maximum ATA is one specification—not a complete description of the experience or protocol.
In this guide, O2genes uses Mild Hyperbaric Oxygen Therapy (mHBOT) for its Soft Shell HBOT cocoon® systems at 1.4–1.5 ATA and Hyperbaric Oxygen Therapy (HBOT) for its Hard Shell HBOT cocoon® systems up to 1.99 ATA. These are product-series labels here—not a claim that pressure alone determines clinical use or outcome.

Five one-person formats built around upright, reclined, lie-down or wheelchair-accessible positioning.

Four models across seated and horizontal formats, with one- to six-person configurations depending on model.
Specifications can change. Confirm the maximum pressure, included equipment and installation requirements in the current quotation for the chosen model.
| Comparison point | Soft Shell HBOT cocoon® | Hard Shell HBOT cocoon® |
|---|---|---|
| Maximum pressure up to | 1.5 ATA for Lumiere, Reverie, Zilsie and Roomiere; 1.4 ATA for Evexia. | Up to 1.99 ATA across Aura, Elixir, Altus and Zia. |
| Chamber structure | TPU chamber supported by a stainless-steel frame. | Rigid chamber body with model-specific seating, viewing and control layouts. |
| Recommended capacity | One person across all five models; choose by posture, access and room footprint. | Aura: 1 person, with 2- and 4-person options; Elixir: 2; Altus: 4, with 2- and 6-person options; Zia: 1. |
| Oxygen delivery | Product-specific concentrator and breathing setup. Confirm it from the supplied oxygen system and breathing setup, not from ATA alone. | Model-specific oxygen system and controls. Confirm the complete supplied configuration. |
| Space planning | Plan for the inflated chamber, frame, equipment, ventilation, clearance and dedicated power. | Plan as a room installation, including access, equipment, ventilation, clearance and dedicated power. |
| Support | Model selection, setup guidance, training, maintenance and local support. | Site planning, delivery coordination, installation, training, maintenance and local support. |
Pressure, oxygen concentration, and exposure time all matter. Multiplying them into a simple score is not a reliable way to treat two devices or session plans as the same. Compare delivery, protocol steps, and the evidence behind each pathway.
Chamber oxygen level and the oxygen a person breathes may not be the same.
Compression, decompression, air breaks, frequency and total sessions can change the exposure.
Match a study result to the chamber, oxygen delivery, and protocol that produced it before comparing systems.
Is the goal a wellness experience, a product purchase, or a medical question?
Which posture, access needs and recommended capacity fit the intended user?
What pressure, oxygen delivery and operating protocol does the exact model use?
Can the room support the required footprint, access, power, ventilation and equipment?
Who will operate, maintain and supervise the system—and who will assess medical suitability?
Review each series’ models, recommended capacity, dimensions, pressure and support before asking for a quotation.
