Protocol
Multiplace chambers accommodate multiple patients simultaneously and are typically found in hospital hyperbaric departments. Patients breathe 100% oxygen through hoods or masks while the chamber is pressurized with air.
Multiplace hyperbaric chambers are large steel or acrylic pressure vessels that hold 2–12 patients at once. The chamber itself is pressurized with air, while patients breathe 100% medical-grade oxygen through tight-fitting hoods, masks, or endotracheal tubes. This design allows a trained hyperbaric nurse or technician (called an inside attendant) to remain with patients throughout treatment — essential for critically ill or unstable patients. Multiplace units operate at 1.5–6.0 ATA and are standard equipment in naval, military, and Level I trauma hospital hyperbaric units.
Quick facts
What happens during a session?
Multiple patients enter the chamber and sit or lie on treatment tables. An inside attendant is present throughout the session. The chamber is pressurized with compressed air to treatment pressure while patients breathe 100% oxygen through hoods or masks. Treatment sessions are typically 90–120 minutes at pressure. This setup allows for IV access, monitoring equipment, and immediate clinical intervention if needed.
What you get from multiplace hyperbaric chambers
- Inside attendant provides continuous clinical monitoring
- Suitable for unstable or ICU-level patients
- Accommodates life-support equipment and IV lines
- Higher maximum pressures available for certain emergencies
- Multiple patients treated simultaneously (efficient for hospitals)
- Emergency abort procedures can be initiated rapidly
Best suited for
- Hospitalized patients needing HBOT alongside other treatments
- Patients with decompression sickness or gas embolism
- Severe burn or necrotizing infection patients
- Patients who are claustrophobic (larger space than monoplace)
- Cases requiring IV medication during treatment
- Critically ill or medically complex patients
- Decompression sickness (diving emergencies)
- Gas embolism
- Necrotizing soft tissue infections
- Severe carbon monoxide poisoning
- Wound care requiring close monitoring
Common questions
Where can I find a multiplace chamber near me?
Multiplace chambers are typically in hospital hyperbaric departments, military medical centers, and some large outpatient HBOT facilities. Search FindHyperbaric and filter by 'multiplace' to find verified clinics.
Is multiplace HBOT more effective than monoplace?
Both achieve equivalent clinical outcomes for most indications. The choice depends on patient condition — critically ill patients benefit from the inside attendant capability of multiplace chambers. For standard outpatient HBOT, monoplace is equally effective.
Can I bring a companion into a multiplace chamber?
Not for comfort — everyone in the chamber must have a medical indication. However, some pediatric programs allow a parent to accompany a child if they also undergo a medical assessment.
How much does multiplace HBOT cost?
Sessions typically range from $200–$350 at hospital-based programs. Medicare and most insurers cover it for FDA-approved indications. Costs vary significantly by facility and location.
