Taravana
Taravana
Taravana (pronunciation: tah-rah-vah-nah) is a medical condition primarily associated with breath-hold diving. The term originates from the Polynesian language, specifically from the Tuamotu dialect, where "tara" means to fall and "vana" means dizziness or madness.
Etymology
The term 'Taravana' is derived from the Polynesian language, specifically the Tuamotu dialect. The word is a combination of two terms: 'tara', which means to fall, and 'vana', which translates to dizziness or madness. This term was used to describe the symptoms experienced by the pearl divers in the Tuamotu Archipelago who would often dive without proper decompression.
Symptoms
The symptoms of Taravana include vertigo, nausea, lethargy, paralysis, and in severe cases, unconsciousness. These symptoms are similar to those of decompression sickness, also known as the bends, and cerebral hypoxia.
Causes
Taravana is primarily caused by repetitive deep diving without adequate surface intervals for decompression. This leads to a build-up of nitrogen in the body, which can cause bubbles to form in the blood and tissues when the diver ascends too quickly. These bubbles can block blood vessels and disrupt the normal function of organs, leading to the symptoms of Taravana.
Treatment
The primary treatment for Taravana is oxygen therapy and hyperbaric therapy, which involves breathing pure oxygen in a pressurized room or tube. This helps to reduce the size of the nitrogen bubbles in the body and restore normal blood flow. In severe cases, hospitalization may be required.
Prevention
Prevention of Taravana involves following safe diving practices, such as limiting the depth and duration of dives, taking adequate surface intervals between dives, and ascending slowly to allow for proper decompression.
