WebMar 23, 2024 · Lung volume reduction surgery (LVRS) has already shown an improvement in diaphragmatic function that could be explained by a change of the diaphragm conformation. More recently, endoscopic lung volume reduction (ELVR) has shown benefits in terms of respiratory function, exercise capacity and quality of life, but the mechanisms … WebOct 20, 2024 · The decision to incorporate more sophisticated tests mainly depends on the available resources and the philosophy of each PR center. 10 Recently, Smargiassi et al have demonstrated the possible role of ultrasound (US) measurement of diaphragm thickness and thickening at the zone of apposition (zapp) at the end of a maximal …
Dynamic changes in the zone of apposition and diaphragm …
WebThe contraction of the diaphragm is visualized at the zone of apposition. This zone of apposition is the area where the abdominal contents meet the lower rib cage. On the right side, the diaphragm lies between the lower rib cage and the liver. It is the ideal area to visualize the diaphragm. WebCostal EMGdi activity was measured on the surface of the lower right chest, the zone of apposition of the diaphragm. Two surface electrodes in bipolar configuration were placed at the seventh and eight intercostal space, one below the other along the anterior axillary line and above the costal margin. Additionally, a common electrode was placed ... shannon murrin mindy tran
