Which statement about a multiplace HBOT chamber is true?

• A. It houses multiple patients and is pressurized with air
• B. It houses a single patient and is filled with 100% oxygen
• C. It cannot deliver 100% oxygen to patients
• D. It is never used for HBOT

Answer: (A)

Multiplace HBOT chambers are designed to treat more than one patient at the same time, with the chamber itself pressurized using ambient air rather than pure oxygen. Oxygen to each patient is delivered through individual breathing devices such as masks or hoods inside the chamber, while the chamber atmosphere remains air. This setup reduces fire risk and allows staff to monitor and assist several patients during therapy. The other scenario describes a monoplace chamber, which is designed for a single patient and is typically filled with pure oxygen. Also, multiplace chambers can indeed deliver 100% oxygen to patients via their breathing devices, even though the chamber atmosphere is not 100% oxygen. And multiplace chambers are used for HBOT.
