Introduction

According to the range of services that a hyperbaric facility needs to provide, different configurations are available - starting from solutions for very narrow spaces and increasing in size and complexity to cater for the requirements of a large hyperbaric hospital.

Three main factors for selecting the correct hyperbaric chamber system are summarized as follows:

  • Space availability and integration with existing facilities
  • Number of simultaneous therapies
  • Typical target therapy and/or requirements for urgent treatment of decompression sickness

 

Types of medical hyperbaric chambers

Monoplace chambers

A monoplace hyperbaric chamber holds one patient at a time.

Main functions of these small chambers are:

  • Emergency medicine and patient transportation, and for military applications
  • Single-patient therapy, in specific international locations where this practice is widespread and regulated

In case of transportation, the chamber can be connected to a larger chamber system with standardized connection flanges.

Higher pressure treatment can use air for emergency diver decompression.

 

Multiplace

Modern multiplace chambers are composed of two or more locks, providing at least one entry lock and one main lock. The entry lock is used to transfer patients or medical personnel without depressurizing the entire main treatment lock. Triple lock chambers also allow the execution of different therapies in the two main locks. This offers the benefit of leaving one of the main locks dedicated to emergency therapies or diver decompression sickness when the center is close to professional or recreational diving areas.

In multiplace chambers the ambient atmosphere is normally pressurized with air. Patients can be treated with oxygen by means of a hood or a mask. Clinical staff can attend the therapy, accompanying patients inside the chamber.

One or more medical locks are also installed, permitting clinicians to transfer medicines, blood samples, and other small objects in and out of the chamber in full safety.

The internal layout can be arranged in different levels of complexity and comfort, outfitting the internal space with comfortable seats, or sufficient space for wheelchairs and stretcher access.

Many multiplace chambers are equipped with video entertainment systems or even personal tablet devices. Communications with the outer environment is ensured by an intercom system.

The risk of fire in multiplace chambers is low since oxygen supply is directed to hoods, masks and connection pipes.

The range of multiplace hyperbaric chambers comprises units suitable for up to 20 patients and more, divided into additional locks. Large facilities can also contain more than one chamber to accommodate larger groups of patients and to support emergency treatments.

 

Rectangular chambers

Nowadays, medical hyperbaric treatment chambers offer an impressive level of integration within hospitals and hyperbaric clinics, especially with respect to rectangular chambers.

These rectangular chambers provide boundaries of the hyperbaric facility similar to a normal division wall, giving more space and comfort for operators and patients. This technology, however, has a big impact on structural requirements of the installation site as the weight of a chamber can duplicate when compared to that of a traditional cylindrical arrangement.

Inflatable chambers

Inflatable devices are often used to carry out “mild hyperbaric oxygen therapy”. The weak structure of an inflatable chamber cannot provide the optimal results of a traditional metal chamber.

For one thing, these soft chambers can only operate at a pressure level lower than that of a hyperbaric chamber, below the threshold of effectiveness.  

Moreover, the soft chambers are often provided with low-cost oxygen generators, which simply raise the oxygen concentration by a small percentage instead of performing a pure oxygen therapy. In reality, the low pressure and the negligible oxygen content contribute to a placebo treatment.

As such, they are not used by hospitals or hyperbaric clinics and are not endorsed by medical hyperbaric research as they cannot provide beneficial therapeutic effects.
