Depth and DCI: What Happened At The CMAS 2025 World Championship

Two serious diving incidents occurred during the CMAS 2025 World Championship. Andrey Matveenko experienced a deep blackout and suspected decompression sickness (DCI). There was a delay in his treatment in a hyperbaric chamber, raising safety concerns. Freediving injuries like DCI need different protocols, as current procedures may not meet the level of risk. CMAS aims to improve safety by considering portable hyperbaric chambers for future events.
