The cause for the disease-related type is not known fully. Increased pressure in the ventilator can injure the alveolus and result in barotrauma. This increase in pressure finally leads to the rupture of the alveolar sac’s membrane.Įlevated Pressure: A regular mechanical ventilator is inserted into a patient. Positive pressure ventilation causes an increase in pressure at the nearby regions of the alveolus. However, mechanical ventilators usually deliver a positive influence. Positive Pressure Ventilation: A normal breathing cycle is chiefly dependent on the negative pressure inside the lungs compared to the pressure of the external atmosphere. The following are the various causes of ventilator-related alveolar rupture. They are ventilator-related or disease-related. It includes either the rupture of the alveoli of the lungs, or it involves a direct injury.
What Causes Barotrauma?īarotrauma mainly occurs due to two reasons.
With this advancement, the rate has reduced so well in a range of more than 10 percent than the earlier time. The recent advancements in the mid-2000s have led to the application of low tidal volume ventilation. The incidence, in this case, ranges from 0 to 50 percent. The incidence of barotrauma during a mechanical ventilation procedure differs based on the underlying indication for mechanical ventilation. Air leaks into extra-alveolar tissue resulting in conditions such as pneumothorax, pneumomediastinum, pneumoperitoneum, and subcutaneous emphysema. Barotrauma can happen due to the increase in trans alveolar pressure. In this way, the tissues in the lungs get disrupted. It occurs due to an invasive mechanical ventilation procedure that leads to alveolar rupture. Pulmonary barotrauma is a common condition. If the condition of barotrauma affects the entire body, then it is called generalized barotrauma or decompression sickness. It happens due to a pressure difference between the gaseous space inside the body and the surrounding external environment. Barotrauma is damage caused to the body tissues physically. It is common in scuba divers and people who travel in jets. Barotrauma is a traumatic change caused due to an alteration in the water or air pressure.
