HBO and cerebral Gas embolism

The bubbles immediately create a vascular obstruction which can be very serious in the brain or heart. The longer you wait, the more the bubbles encyst, because they attract white blood cells and platelets, and become difficult to eliminate. Blood vessels are physically damaged by the bubbles and secrete substances that make them permeable, which promotes edema.
It is therefore an emergency situation because the longer we wait, the greater the damage will be.
HBOT acts immediately by compressing the bubbles, removing nitrogen by diffusion and delivering large amounts to the tissues allowing them to survive until the bubbles are eliminated.
