![]() Similarly, the compressed air held in a diver’s lung, if he holds his breath, will expand as the surrounding water pressure decreases on the ascent. A balloon that rises in the atmosphere will expand in volume as the ambient pressure decreases. ![]() EtiologyĪccording to Boyle’s Law of Gases, if the temperature of a gas is held constant, there is an inverse relationship between the volume of the gas and its pressure. This causes embolic blockage of the circulation at distant sites or interferes with normal organ function. Tears in pulmonary tissue can allow gas to enter the circulation. Barotrauma most usually causes sinus injury or middle-ear injury, but may also cause facial injury, tooth injury, gastrointestinal (GI) rupture, pneumothorax, pulmonary hemorrhage, mediastinal and subcutaneous emphysema. The damage is due to compressive/ expansive forces and shear, leading to overstretching of tissues. Summarize interprofessional team strategies for improving care coordination and communication to advance the treatment of barotrauma and improve outcomes.īarotrauma is physical tissue damage caused by an unrelieved pressure differential between a surrounding gas or fluid and an unvented body cavity (e.g., sinuses, lungs), or across a tissue plane.Review the treatment and management options available for barotrauma.Outline the presentation of barotrauma.This activity reviews the causes, presentation of barotrauma, and highlights the role of the interprofessional team in its management in order to improve outcomes. Barotrauma can cause sinus injury, ear injury, facial injury, tooth injury, an acute abdomen, pneumothorax, pulmonary hemorrhage, and subcutaneous emphysema. This causes potential blockage of circulation at distant sites or interferes with normal organ function. Occasionally, tears in tissue can allow gas to enter the body through the initial trauma site. As a gas-filled space expands or contracts, it can cause damage to the local tissue. The damage is due to shear or overstretching of tissues. Barotrauma is physical tissue damage caused by a pressure difference between an unvented space inside the body and surrounding gas or fluid.
