In this report, I provide a detailed account of a serious decompression sickness (DCS) incident I experienced during a series of cave dives in Tulum, Mexico. While the case includes medical and technical analysis, the primary focus is on the psychological aspects of the event—how decisions were made under pressure, the influence of cognitive biases, and the progression from early warning signs to a critical outcome. My aim is to contribute to the broader understanding of diver behavior and risk management, particularly among technical divers, instructors, and dive medical professionals.
I would like to express my deepest gratitude to Lionel Wolovitz and Ruben Castillejo Argote, whose decisive actions immediately after surfacing were critical in ensuring my safety during the most vulnerable phase of the incident. Their focus and resilience were instrumental in the early response. I am especially thankful to Dr. Eduardo Rovirosa at the Playa International Clinic, who led my medical treatment with exceptional care and expertise. His swift intervention and clinical judgment were central to my recovery. I also extend my thanks to Cristian Pellegrini at DAN Europe, as well as Alessandra Figari, Peter Broger, and Jaime De La Puerta Salazar, who played key roles in coordinating my treatment and support. Additional appreciation goes to Dr. Lara Lambiase and the broader DAN Europe medical team for their ongoing care and follow-up. Finally, I am profoundly grateful to the many friends—and even people I had never met—whose messages of support provided strength and encouragement throughout the ordeal.
