2026 Winter Symposium: Elevating Care Under Pressure: Medicine at the Crossroads of Safety, Compliance, and Performance

This year’s Winter Symposium will focus on the convergence of undersea, hyperbaric, and aerospace medicine through the lens of human performance, human factors, and risk mitigation. As operational demands grow in diving, hyperbaric, and aerospace domains, our symposium will explore how interdisciplinary approaches can protect, enhance, and sustain human function in extreme and unforgiving environments.
We will place a strong emphasis on lessons learned from accidents, near-misses, and system failures in diving, hyperbaric operations, and aviation, using these to drive improvements in clinical protocols, safety culture, and mission outcomes. This course will feature speakers prominent in their field and will provide time to question and interact with these experts in the friendly confines of The Lodge at Whitefish Lake. Seat are limited, register for the meeting today!

July 11, 2025: Statement from the Undersea and Hyperbaric Medical Society (UHMS) Regarding the Incident in Lake Havasu City, Arizona

The Undersea and Hyperbaric Medical Society (UHMS) has been made aware of an incident involving a reported fire at a facility in Lake Havasu City, Arizona, on July 9, 2025. At this time, early reports are still emerging, and many critical details surrounding the nature and cause of the incident remain under investigation.

Our thoughts are with all those affected, including patients, staff, emergency responders, and the broader healthcare community in the region. We extend our support to local authorities and organizations as they work to assess the situation and ensure the safety and well-being of all involved.

UHMS is closely monitoring developments and is committed to providing accurate, responsible information. As additional facts become available and verified through appropriate investigative channels, we will offer further updates and context, particularly as they pertain to hyperbaric facility safety and operations.

In the interim, we urge the public and media to respect the investigative process and allow authorities the time needed to conduct a thorough review. The UHMS remains available to support our members and partners during this time and will continue to advocate for the highest standards of safety in the provision of hyperbaric medicine.

In Memoriam: Kevan Corson, CHT
Dedicated Leader, Educator, and Advocate for Hyperbaric Safety

It is with deep sadness and profound respect that we honor the life and legacy of Kevan Corson, CHT, a long-standing pillar of the Undersea and Hyperbaric Medical Society (UHMS) Safety Committee and a tireless advocate for hyperbaric medicine and safety worldwide.

Kevan’s career was marked by unwavering dedication, innovation, and service. A retired U.S. Army Special Forces medic, he brought a unique blend of tactical precision and scientific rigor to every endeavor. As a research scientist at the Texas Health Science Center in San Antonio, Kevan led the CORE Lab within the Department of Cellular & Structural Biology and contributed extensively to the Department of Obstetrics and Gynecology, teaching senior fellows the art of microscopic suturing—a testament to his skill and commitment to education.
His journey in clinical hyperbaric medicine began at the University of Texas Medical Branch in Galveston under the mentorship of Dr. Jon Mader. There, Kevan co-authored three book chapters and fourteen peer-reviewed papers and abstracts, establishing himself as a respected voice in the field. Over a career that spanned more than three decades, Kevan made indelible contributions to hyperbaric oxygen therapy, receiving numerous accolades including the prestigious Paul C. Baker Award in 2004 for his outstanding service to the hyperbaric community, and the Oceaneering International Award.
As a longtime UHMS HBO2 Safety Committee member in good standing, Kevan served the UHMS with distinction for over 20 years, shaping national and international safety standards. He was also a dedicated member of the National Board of Diving and Hyperbaric Medical Technology for over 18 years, served on the Association of Diving Contractors International Saturation Safety Committee, a trusted contributor to the ASME PVHO Task Group on Tunneling, and a board member for CAL OSHA Appeals for compressed air tunneling.

Beyond the academic and regulatory spheres, Kevan made a tangible impact on the field. As Hyperbaric Operations Manager for the Blue Plains Tunneling Project, he brought critical hyperbaric safety expertise to some of the nation’s most complex tunneling operations. Throughout his career, he trained more than 2,000 healthcare professionals in hyperbaric medicine, leaving behind a legacy of excellence and a generation of safety-conscious practitioners.

Kevan Corson was more than his many titles and achievements. He was a mentor, a leader, a colleague, a friend and above all the finest human being. His legacy will endure through the lives he touched, the standards he elevated, and the countless individuals who continue to work more safely because of his tireless advocacy.

On behalf of the UHMS Safety Committee and the entire hyperbaric medicine community, we extend our deepest condolences to his family, friends, and colleagues. We are forever grateful for his service, and we honor the enduring impact he has had on our field.

Rest in peace, Kevan. Your mission continues through us.

Respectfully,
The UHMS Hyperbaric Oxygen Safety Committee
