Helium is commonly used with oxygen helioxeven though helium is expensive and has a high thermal conductivity, which potentiates heat loss and can make hypothermia a serious possibility on deep dives. It involves no pressure changes in the body and is usually performed to enhance breath-hold time. Open in a separate window. Your provider will perform a physical exam and ask about your symptoms. Hyperventilation has little effect on the oxygen content of the body but blows off carbon dioxide so that you start with a higher cerebrospinal fluid pH. Retrieved

    CO 2 will also accumulate in the tissues of the body, resulting in respiratory acidosis. This can lead to unconsciousness. Or, it can be due to a medical problem, such as bleeding or infection. In apnea, CO 2 is not removed through the lungs and accumulates in the blood. On deep dives the composition of the gas breathed is changed several times during descent and ascent.

Flushing the system with pure oxygen periodically overcomes this problem, but high partial pressures of oxygen increase blood pressure and reduce heart rate. When to Contact a Medical Professional. Archived from the original on 27 September During the breath hold the oxygen content of tissues decreases, but the breath hold is broken as a result of carbon dioxide production and resulting acidosis, which stimulates the respiratory centre.

    It is relatively insoluble in lipids, minimising bubble liberation on decompression.
