What is the most common complication of HBO?
Barotrauma is a term that refers to injury due to increased pressure. Barotrauma of the ear is the most frequent complication of HBO. The middle-ear is an air-filled cavity behind the ear drum that connects to the throat through a slit-like passage called the eustachian tube. During compression, if the air pressure in the middle-ear cannot be equalized with the external pressure, the eardrum will bow inward, leading to pain and possibly rupture, leading to hearing loss.
What is decompression sickness?
Decompression sickness, or the bends, is a result of the uptake of nitrogen into the blood when air (which is about 80 percent nitrogen) is breathed at increased ambient pressure. This is generally more of a concern for the inside attendants, who breathe air during a treatment, rather than patients, who are breathing 100% oxygen. This can become a concern if a patient must be removed from oxygen for prolonged periods of time during the dive. Decompression sickness can result in pain, neurological injury, cardiopulmonary collapse, and possibly death.
Can hyperbaric chambers cause claustrophobia?
Due to the confined and enclosed nature of the hyperbaric chamber, some patients can develop a feeling of claustrophobia, and those who are already claustrophobic can experience a worsening of their symptoms. A multi-place chamber (such as we operate) can help alleviate some of these feelings due to the size of the chamber.
Is hyperbaric oxygen therapy dangerous?
As with all medical treatments, hyperbaric oxygen therapy includes medical risks and possible side-effects. Most are related to the unique aspects of HBO such as significant and relatively rapid changes in pressure inside the chamber and the high levels of oxygen used. Most are relatively mild and self-limited, but some can be severe and even life-threatening.
Does oxygen therapy affect myopia?
Visual refractive changes. Hyperbaric oxygen therapy treatments can temporarily change the shape of the lens in the eye.
