· the object

A roomier sitting-style portable — proportioned for a held, quiet hour.

Meridian is a soft-shell portable chamber operating at 1.3 – 1.4 ATA. The envelope is IPU — a polyurethane composite fiber clip-mesh cloth — supported by an internal metal frame so the chamber holds its shape between sessions. Entry is through a three-zipper seal, secured against air loss. An observation window keeps the room visible from inside.

The controller pressurises room air rather than pure oxygen. A built-in silencing device keeps operating noise low. A memory-foam mattress with an antibacterial cotton-and-bamboo cover finishes the interior. Designed for single-operator use — no assistant required.

A short list of safety notes.

  1. 01 A soft-shell chamber pressurises room air through an external concentrator. It is not flammable in the way a pure-oxygen chamber is — but should still never be exposed to a naked flame or lit cigarette.
  2. 02 Ear discomfort during pressurisation is common; swallowing, yawning, or chewing helps. First-time users may feel briefly tired or light-headed.
  3. 03 Children under 16 should be accompanied by an adult inside the chamber.
  4. 04 Consult a qualified healthcare provider before beginning any new practice — Echelon Hyperbarics does not provide medical advice.
