What is barotrauma in mechanical ventilation? Barotrauma is a condition in which the alveoli (air sacs of the lungs) rupture with a subsequent entry of air into the surrounding extra alveolar space. Barotrauma is typically caused by lung air sacs rupturing or a direct injury. Barotrauma can complicate mechanical ventilation, as it is associated with life-threatening conditions or even death. Hence, …
