Lung membrane defects

A. the cause of Hyaline Membrane disease is pre-mature birth. while the fetus develop, about in the 29th week a substance called surfactant is created in the lungs. this substance's function is to change the surface tension of the fluid in the lungs- therefore decreasing it's force. the surface tension tends to shrink the lungs and can cause the lungs to collapse. so a premature baby wouldn't ...

Jan 26, 2017 · Last Editorial Review: 1/26/2017. Hyaline membrane disease: A respiratory disease of the newborn, especially the premature infant, in which a membrane composed of proteins and dead cells lines the alveoli (the tiny air sacs in the lung), making gas exchange difficult or impossible. ECMO (extracorporeal membrane oxygenation) is a device that takes over the function of your lungs. It uses a machine to remove carbon dioxide from your blood and circulate oxygen throughout your body when your lungs cannot function on their own. ECMO may often be referred to as ECLS (extracorporeal life support) or heart/lung bypass.

Feb 03, 2018 · On the whole, when production of mucus in lungs exceeds its normal level, it is sign of a viral infection or even a respiratory disease. The cause of mucus buildup, that causes nasal and chest congestion, need to be ascertained, to diagnose the condition. Thus the characteristic findings of an obstructive defect on pulmonary function testing include a reduction in FEV 1, a reduction in the FEV 1 /FVC, and an increase in RV with either a normal or increased TLC. Occasionally, in mild obstructive lung disease, the only defect which may be seen is a reduction in FEF25-75.

As the alveoli collapse, damaged cells collect in the airways, which makes it even harder to breath. These cells are called hyaline membranes. Your baby works harder and harder at breathing, trying to re-inflate the collapsed airways. As your baby's lung function decreases, less oxygen is taken in and more carbon dioxide builds up in the blood. Rationale: Patients with interstitial lung disease and acute respiratory failure have a poor prognosis especially if mechanical ventilation is required. Objectives: To investigate the outcome of patients with acute respiratory failure in interstitial lung disease undergoing extracorporeal membrane oxygenation (ECMO) as a bridge to recovery or transplantation. Obstructive lung diseases are characterized by an obstruction in the air passages, with obstruction defined by exhalation that is slower and shallower than in someone without the disease. Obstruction can occur when inflammation and swelling cause the airways to become narrowed or blocked, making it difficult to expel air from the lungs. The pleura is the membrane that lines the thoracic (chest) cavity and covers the lungs. It is like a large sheet of tissue that wraps around the outside of the lungs and lines the inside of the chest cavity. There are several types of pleural diseases, including: Pleurisy - an infection of the pleural cavity.
