Explanation of IEDCS
Decompression illness occurs due to the accumulation of inert nitrogen gas accumulated during scuba diving or escaped gas due to a rapid ascent. When these bubbles affect the inner ear then it is termed a vestibular or inner ear decompression illness (IEDCS).
Divers will experience disruption to their balance system on one side resulting in sudden onset vertigo, nausea and imbalance. Sometimes this can be associated with hearing loss and/ or tinnitus.
It can be difficult to distinguish between IEDCS and pressure damage to the inner ear caused by forcefully clearing the ears during diving. Therefore, it is important to have a thorough assessment by a dive doctor to establish the diagnosis. If you do experience IEDCS then it is important that you contact your nearest hyperbaric chamber as soon as possible for recompression therapy.
Recovery from IEDCS can require several recompression therapy treatments. Your dive doctor will assess you before and after each treatment to monitor your progress and once your symptoms have resolved or stabilized then you will be discharged home.
Balance retraining and vestibular exercises can help your body to start to compensate for the damage in the inner ear, so it is important to start these as soon as possible after your injury. A balance retraining booklet and video resources are available via the Vestibular Rehabilitation link below.
