Pressure Change and Barotrauma

Pressure Change and Barotrauma

How diving affects the body’s air-filled spaces

Live Event: Thursday, February 18, 2021 7PM ET

The pressure changes associated with diving have significant effects on the lungs, ears, sinuses and other gas-filled cavities of the human body. In this lecture, Matias Nochetto, M.D., discusses the mechanisms and outcomes of barotraumas in diving — from the mundane to the rare and bizarre. With a better understanding of how barotraumas happen, divers and dive professionals will be better able to both prevent and treat them.


Presented by Matias Nochetto, M.D.

Matias Nochetto, M.D., is the Director of Medical Services at DAN, where he has worked since 2006. He is co-director of the DAN-UHMS continuing medical education program and a faculty member of several national and international diving medicine courses and programs. He became a dive instructor (1999) during medical school, which led him to complete a three-year clinical and research fellowship in hyperbaric and diving medicine to combine the two passions.

Training Courses You May Enjoy

Whether it’s being on the scene of an accident or witnessing a medical emergency, most people will be involved in a crisis at some point in their lives. DAN’s training courses prepare people to step up and take action should these situations arise.

Diving First Aid for Professional Divers

Professional divers have unique responsibilities and a duty to respond to unique situations; their first-aid training should not be any less unique. DAN’s Diving First Aid for Professional Divers course is designed for commercial, professional, aquarium and scientific divers, and it provides knowledge and first-aid skills specifically for these work environments.

Basic Life Support: CPR and First Aid

This fundamental course prepares you to provide proper care for life-threatening illnesses or injuries until professional emergency medical care is available. The life-support skills taught in this course include one-person CPR, use of automatic external defibrillators, bleeding management, assisting a choking victim and responding to a person in shock.

Emergency Oxygen for Diving Injuries

Administering emergency oxygen is the preferred first aid for scuba diving injuries, and early administration can drastically improve the outcome for an injured diver. The DAN Emergency Oxygen for Scuba Diving Injuries course teaches you how to administer life-saving oxygen first aid to divers who may be suffering from decompression illness (DCI).
