1. Basic Definition of a Hyperbaric Chamber
A hyperbaric chamber is a sealed, pressure-controlled medical device for treatment and rehabilitation. It raises internal pressure above atmospheric levels, allowing users to breathe high-purity oxygen. It is core equipment for hyperbaric oxygen therapy in hospitals and rehabilitation institutions, with strict safety standards.
2. How It Works in Simple Terms
Under normal pressure, blood oxygen solubility is limited. In a hyperbaric chamber, increased pressure and high oxygen concentration significantly boost oxygen dissolved in plasma, delivering sufficient oxygen to hypoxic tissues, relieving hypoxia, accelerating metabolism, and promoting tissue repair.
3. Core Medical and Clinical Uses
Hyperbaric chambers are used in emergency treatment, rehabilitation and postoperative recovery, including: rescuing carbon monoxide poisoning and diving decompression sickness; assisting in treating hypoxic encephalopathy, brain trauma and cerebrovascular disorders; accelerating wound healing; and conditioning for hearing loss and hypoxia-related fatigue.
4. Common Classification Scenarios
Hyperbaric chambers fall into two categories: large medical multi-person chambers (in hospitals, for severe cases, with full monitoring) and small portable single-person chambers (for daily rehabilitation, not for emergencies).
5. Important Safety and Usage Precautions
Hyperbaric chambers require professional operation. Users need pre-treatment physical assessments to rule out contraindications. Flammable items are prohibited. Pressure changes must be slow to avoid discomfort, and unqualified household equipment is not recommended.
