what does a hyperbaric chamber do

A hyperbaric chamber creates a controlled, high-pressure environment where a person breathes 100% oxygen at pressures typically 1.5 to 3 times normal atmospheric pressure. This therapy increases the amount of oxygen the lungs can absorb and helps deliver more oxygen through the blood to body tissues. The enhanced oxygen levels promote healing of damaged tissues, fight certain infections, and reduce the size of gas bubbles in the blood, making it effective for treating conditions like decompression sickness, carbon monoxide poisoning, non-healing wounds, radiation injuries, and infections.
