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 …

What is pulse oximetry? Dr. Richard Levitan, MD, says that the use of home finger pulse oximeters by patients with COVID-19 could preempt the precipitous oxygen desaturation that leads to a crisis that needs intensive care. Pulse oximetry is a quick, noninvasive test that measures the oxygen level (oxygen saturation) in the blood. It is an easy, painless method to measure …

What is a pleurectomy? A pleurectomy is a surgical procedure that is done to remove part of the pleura. Pleurectomy is indicated for an individual who has recurrent lung diseases or infections. Lungs are surrounded by a thin lining called pleural membrane (pleura). Pleura help lungs move with ease during respiration. A pleurectomy is a surgical procedure that is done …

What is a pleural biopsy? Three types of pleural biopsies are needle biopsy, thoracoscopic biopsy, and open biopsy. A pleural biopsy is a procedure used to remove a sample of the pleura using a special biopsy needle during surgery to diagnose disease, infection or cancer. Pleura is a thin tissue that lines the chest cavity and surrounds the lung. A …

What is noninvasive ventilation? Invasive ventilation: The type of ventilation where oxygen is delivered to your lungs through a tube inserted into your nose or throat (endotracheal tube or tracheostomy tube) that goes into your windpipe. A ventilator is a machine that helps in delivering oxygen to your lungs. It is used to assist with breathing when you cannot breathe …

What is decortication? Decortication is a surgical procedure that removes the restrictive layer of fibrous tissue overlying an organ. It is mostly performed to remove the fibrous layer over the lung, chest wall, and diaphragm. Pleura is a thin membrane that lines the outer surface of the lungs (visceral pleura) and the inner surface of the chest wall (parietal pleura). The …
