Continuous flow is the standard oxygen system on our chambers, and for most people it is all they need. BIBS is the upgrade for the cases where it isn’t. If you have read about continuous flow and want to know what the step up actually buys you, here it is in plain terms.
The short version
BIBS stands for Built-In Breathing System. Like continuous flow, it delivers oxygen through a mask while the chamber holds pressure. The difference is timing: instead of a steady stream, BIBS releases oxygen in time with your breathing and routes your out-breath away. Because almost nothing is wasted, it lands at close to 100% effective, against around 70% for continuous flow. The full specs and FAQs live on the BIBS system page; this is the plain-English version.
How it works
The chamber pressurises around you in the usual way and you breathe through the mask. As you inhale, the mask releases oxygen; as you exhale, that breath is exhausted out rather than lingering. Oxygen is delivered on demand, matched to your breathing, instead of flowing constantly. That is the whole mechanism, and it is why BIBS is sometimes called a demand system.
Why it reaches close to 100%
With continuous flow, the oxygen streams at a steady rate, so some of it passes by in the gaps between your breaths. BIBS removes that waste by only delivering when you actually breathe in. Almost all of the oxygen the system provides is oxygen you take in, which is the entire point of the upgrade.
What you trade for it
BIBS is the step up, so it is priced as an upgrade rather than included as standard. The breathing also feels a little different: oxygen arrives in time with your breath rather than as a constant stream, which most people find natural within a few sessions. There is nothing extra to manage day to day beyond the normal mask routine.
Who it is for
BIBS makes the most sense if your sessions depend on getting the most from every breath, or if you have run continuous flow for a while and want to step up. You do not have to choose once and for all, either: with BIBS fitted you can still run a standard session, so many owners use BIBS for their higher-purity sessions and continuous flow for everyday ones.
Standard or upgrade?
If you are deciding between the two, the honest answer is that it depends on what your sessions are for. Our continuous flow vs BIBS guide puts them side by side. BIBS is an upgrade on the Atlas One, and the exact cost lands in your custom quote rather than a sticker price, because it depends on your configuration.
