Gerardo Bosco

MD, PhD

Session Topic

HBOT in Sport Injury Recovery Training

Dr. Gerardo Bosco is presenting on hyperbaric oxygen therapy in sport injury recovery and training-related applications.

Read bio

MD and associate professor in exercise and sport sciences at the University of Padua. Specialist in Diving and Hyperbaric Medicine, a PHD in muscle pathophysiology and a residency in Nutritional Sciences (Internal Medicine). After focusing my work on basic and clinical sciences on diving and hyperbaric medicine in 2015 I became director of a Master level II in Diving and Hyperbaric Medicine. My mission in research and education is to promote prevention techniques, develop techniques to monitor patients undergoing to HBOT, and get the peak performance in elite athletes and divers, based on the study of human metabolism through different methods: invasive (blood sampling and instrumental analyses) and non-invasive such as oxygen consumption and the determination of oxidative stress and blood transmitters in saliva and urine. My goal is to investigate human metabolism and physical exercise both on the land and in the water, to discover the correct dosage of work out and oxygen, and promote new conditioning and recovery strategies to improve the performance of athletes and the quality of life of sedentary people and patients. I truly believe in interdisciplinary collaboration, promoting the growing of new research fellows worldwide.

HE WORKED AS A STAFF IN PARMA (ITALY) FOR 4 YEARS, WITH SPECIFIC CLINICAL INTEREST FOR BOTH REGIONAL ANESTHESIA AND HYPERBARIC MEDICINE. HIS CURIOSITY FOR RESEARCH OPPORTUNITIES IN HYPERBARIC PUSHED HIM TO PURSUE A HYPERBARIC MEDICINE FELLOWSHIP AT TGH, TORONTO IN 2018. THE PLAN WAS TO STAY FOR ONE YEAR, BUT HIS SECOND INTEREST (REGIONAL ANESTHESIA) GOT HIM INTO A SECOND FELLOWSHIP IN REGIONAL ANESTHESIA AT TWH, AND THEN HE FOUND A PERFECT STAFF POSITION AT TWH, WHERE HE CAN COMBINE HIS 2 INTERESTS. CURRENTLY, HE IS ASSISTANT PROFESSOR AS A CLINICIAN RESEARCHER AT THE UNIVERSITY OF TORONTO, WITH SPECIFIC INTEREST IN HYPERBARIC OXYGEN; REGIONAL ANESTHESIOLOGIST STAFF, ANESTHESIA FELLOWSHIP PROGRAM COORDINATOR AT TWH.

Part 4 Moderator

Daniel Gericke will moderate Part 4 of the symposium, focused on hyperbaric chamber fire safety and operational safety.

Read bio

Mr. Gericke served in the South African Navy Marines and Diving Unit, specializing in underwater explosive clearance, as well as teaching the technique. He became the Director of the South African Navy Decompression Chamber Program, treating HBOT patients in addition to decompression illness. He is responsible for a lot of firsts in the hyperbaric field. He founded the first multiplace hyperbaric medical centre in South Africa at Saint Augustine’s Hospital in Durban and then followed this up by establishing a sister monoplace facility at Milpark Hospital in Johannesburg. The first hyperbaric chamber for Milpark wasn’t just purchased. It was designed and constructed specifically for the facility. Daniel has 30 years’ experience in hyperbarics and has gained this experience in many locations. Moving to Bermuda, he became Safety Director at the Bermuda Hospitals Board and the Island’s multiplace facility achieved its first safety accreditation. Due to Daniel’s stewardship, Bermuda’s King Edward Memorial Hospital Hyperbaric Centre was chosen as a Divers Alert Network (DAN) Preferred Provider Facility. Daniel was nominated as DAN International’s Top Instructor Trainer. Later in Canada, Daniel was Technical and Safety Director at the Judy Dan Research & Treatment Centre in north Toronto. He also worked part time at Toronto’s Rouge Valley Hyperbaric Centre. With a particular ability to explain HBOT in terms that are easily understood, he has given generously of his time to others setting up hyperbaric facilities and has provided talks on various aspects of hyperbarics at both ends of the country. He served two terms as Secretary of the Canadian Undersea and Hyperbaric Medical Association (CUHMA), participating in putting together CUHMA’s Guidelines to the Practice of Hyperbaric Medicine in Canada. He also assisted with several Hyperbaric Clinic Risk Assessments and has been part of the planning committees for CUHMA conferences. Although at some distance, he currently serves as HBO Chamber Operations Training Director for the Southern African Undersea and Hyperbaric Medical Association (SAUHMA).
