A multiplace chamber is designed to allow more than one person to receive treatment at the same time. These chambers usually fit between 5 and 6 patients, and, instead of filling the entire space with pure oxygen, everyone has their own mask or hood which delivers the pure oxygen.
Since the room air pressure is not as high as a monoplace chamber, patients can often receive treatment while wearing their normal clothes and can bring in reading materials or their favorite mobile devices.
These models are most often employed in hospitals and trauma centers – places in which treating multiple patients at once is a regular occurrence. While they may not be quite as efficient as monoplace chambers, they are still FDA-approved to treat many conditions.
However, many patients find that breathing through a mask or hood can be a little uncomfortable, and others don’t enjoy spending time in confined areas with a number of strangers.
On top of that, it’s harder to provide individualized hyperbaric oxygen treatments, at least compared to the precise procedures of monoplace chambers.
