The HAUX-DUOX chamber system can accommodate two lying or two sitting patients. A control station is situated at the front of the chamber allowing the operator to see the patients through an inspection window and to treat them accordingly. A HAUX-TALKMASTER intercom system is used for communication between the operator and the occupants. Inside the HAUX-DUOX chamber system is a main chamber and an ante chamber. The patients can breathe air or oxygen by using a breathing mask within the main chamber. The ante chamber is used in order to lock in or out either the doctor or a patient.
