Use guide
Running A Session Step By Step
Choose the diameter
Match the size to the widest intended user before ordering - the larger diameters add shoulder room.
Set the pressure configuration
Specify 1.3 ATA or 1.5 ATA at order; this is a build configuration, not a session setting.
Connect and seal
Attach the hose set to the All-in-One system and close the reinforced zipper.
Run the session
Pressurise and deliver oxygen at up to 93-95% through mask or nasal cannula.
Store between uses
Depressurise, air the interior and fold the chamber for storage if the room is needed for something else.
