Oxygen Conserving Devices

Oxygen conserving devices (OCDs) extend the lifespan of your portable oxygen cylinder (up to six times).

OCDs attach to all portable oxygen cylinders, delivering oxygen only when you breathe in, therefore conserving the amount of oxygen you use.

With an OCD you can travel longer and use either smaller or fewer portable cylinders.

RANA has a selection of easy-to-use OCDs for you to choose from; some require batteries.
