It occurs when the tiny air sacs alveoli within the lung become deflated or possibly filled with alveolar fluid. Atelectasis is one of the most common breathing respiratory complications after surgery. Atelectasis due to compressed lung tissue occurs most commonly when air, blood, pus, or chyle is present in the pleural space.
Lack of surfactant coating on the alveolar surface from pus, fluid or cell, debris can cause increased surface tension and subsequent alveolar collapse. Surfactant reduces surface tension and keeps the alveoli open. In conditions where there is loss of surfactant, the alveoli collapse and become atelectatic. In pulmonary embolism due to loss of blood flow and lack of CO2, the integrity of surfactant gets impaired. Can you die in your sleep from pulmonary embolism?
A heart attack or pulmonary embolism usually will cause enough pain to lead the person to wake and go to an emergency room. But death during sleep with no symptoms at all is likely due to the heartbeat going haywire. Can fluid overload cause pulmonary embolism? Other heart-related problems that can lead to pulmonary edema include: Fluid overload — this can result from kidney failure or intravenous fluid therapy.
Hypertensive emergency — a severe increase in blood pressure that puts excessive strain on the heart. How quick is death from pulmonary embolism? In some cases, the clots take time to build up and may take days or weeks. However, once they join together and travel up to the lungs as one big clot, they can be fatal. The sudden blocking of the pulmonary arteries by a blood clot can cause death in minutes, says Dr Ngunga.
To decrease atelectasis risk, keep small objects out of reach of children. In adults, atelectasis most commonly occurs after major surgery. If you're scheduled for surgery, talk with your doctor about strategies to reduce your risk. Some research suggests that certain breathing exercises and muscle training may lower the risk of atelectasis after certain surgeries. Mayo Clinic does not endorse companies or products.

The pulmonary vascular disease is generally defined as an anatomical narrowing of the pulmonary vascularization. In a broader sense, it can also be defined as a change in the pulmonary vascular impedance in certain regions, which comes from anomalies in the lumen or the walls of pulmonary vessels. There are different clinical situations that cause pulmonary vascular disease, where gas exchange can be evaluated using the multiple elimination techniques.
