A BIBS, or built-in breathing system, is a sealed mask. It runs on two tubes. One brings fresh oxygen in, the other carries exhaled CO2 out of the chamber instead of back into it.
Sealed mask versus open mask
An open mask sits loosely on the face. Some of what you breathe is chamber air, so the concentration reaching you is lower than what the concentrator puts out.
A sealed mask does not mix. You get 90 to 98 percent, and what you breathe out leaves the chamber.
The trade-off is the seal itself. A mask clamped to your face for an hour does not suit everyone.
The problem the OmniBreath dial solves
Until now you picked one system before the session started and lived with it. Users who found the sealed mask claustrophobic gave up on it and lost the higher concentration.
OxyRevo built a custom switch. One dial, two positions, changed mid-session without disconnecting anything.
| Dial position 1 |
BIBS mode, sealed mask |
| Dial position 2 |
Regular oxygen mask mode |
| Oxygen concentration in BIBS mode |
90% to 98% |
| Tubing |
One tube oxygen in, one tube CO2 out |
| Switching |
Mid-session, no disconnection |
| Bundled with |
20 LPM concentrator upgrade |
Start on the regular mask. If you want the higher concentration, turn the dial. If it stops being comfortable, turn it back.
This option is bundled with the 20 LPM concentrator upgrade. Do not also add the standalone 20L Oxygen Concentrator System.
