If oxygen poisoning develops in the pressure chamber treatment;

• Enables hyperventilation with air in the pressure chamber.

• If convulsion develops, it will prevent damage to itself and its surroundings.

• The sedative drug can be started with the recommendation of the underwater physician.

• If symptoms have disappeared after interruption of treatment within 15 minutes, it will be

The first intervention should be to prevent the diver from deeper to reduce the effect of anesthesia. The lifeguard must prevent the unconscious movements of the diver, such as removing the regulator from his mouth and holding his breath. He must think that the dive is like a

The diver must be closely followed when he comes out of the water. There is no treatment to be done when the anesthetic effect is passed. During close follow-up, hypoxic findings, drowning, sudden outbreaks, etc. should be considered and examined for secondary problems. The underwater physician should be consulted if such cases are found to be present.

When medications that prevent convulsions are used before the dive, the convulsion is under control, but cell damage is still present. This causes the diver to reach uncontrolled depths and be exposed to more toxic effects. The only safe approach is to make diving plans at depth limits. This limit depends on the partial pressure of the oxygen, the duration of the dive and

Underwater physicians test the candidates who are susceptible to CNS oxygen poisoning. The oxygen tolerance test can be done by oxygen breathing in the hyperbaric oxygen therapy device at 2.8 ATM for 30 min. Although this test is susceptible to positive ones, there is no clinical validity of the "oxygen tolerance test." Tolerance can vary from person to person or

In the simplest case, it is necessary to avoid high partial pressures of inert gases during diving. It is important to be aware of the circumstances of air diving and know that performance and decision-making authority will be affected at depths of over 40 m. In professional diving, it is necessary to use less narcotic gases such as helium to increase the depth of safe diving. It is known that the adaptation of the dive with the daily dives against nitrogen narcosis. Some studies have shown that although some personal adaptations can occur, reaction times do not

dream, and he should try to go to ascend from the depth.

When the symptoms disappear, and the diver feels ready, the dive may return. It should be noted here that nitrogen is a secondary health problem that will develop in a diver who is forced to exit during narcosis. If necessary, the diver should be re-examined [2].

In diving accidents, the treatment of hypoxic injuries is more important than oxygen poisoning. Therefore, priority should be given to the treatment of diving accidents. In the treatment of decompression, air or gas mixtures can be used in the pressure chamber to reduce the most toxic damage. Vitamin A, C, E, selenium, and so on to reduce oxygen poisoning. Antioxidant products can be used in hyperbaric oxygen therapy or before diving [7].
